    So you can upgrade or just get another truck
    similar to the one you have. Do you have any
    aftermarket items and if so will they transfer
    them to the new truck and what if the items can't
    be transferred, will the dealer/chevy replace them? I don't suppose they would let you pick out
    some other Chevy product instead of the truck? Are
    you going to replace a 99 with a 2000? or does it
    have to me a 99. Thanks for the update.
  • ovalleyovalley Member Posts: 135
    Basically from what I know right now, I have the option of choosing any Chevy vehicle (99 or 00), not just another truck. The catch is they charge you the difference in MSRP between the vehicle you have and the one you choose. So you are paying top dollar for the upgrade. I am still trying to determine if this is negiotable. My dealer tells me that you can even order a new vehicle. I'm not being charged for mileage, but in your case if you are waiting it may cost you a little more. The difference in price is either paid in full when you get the new vehicle or you can start over and refinance. If you refinance, you loose the interest you have paid so far.

    The only upgrade I have is a "removable" bedliner and tinting on the windows. I am still checking on reimbursement for the tinting. Once you find your new vehicle it take 7-10 days for GM to process the paper work and send it to your dealer, then you are free to go.

    I'm going for the 2000. Small price increase and can not find 1999 with similar options. Reg cabs hard to find. I'll let you know how things turn out.

    Thanks for the info, I am going to give my dealer one more shot at fixing my problems then I'm gonna approach them . I don't think I'm going
    to get another truck. I hate to do it but I'm either going back to the Blazer or a car. Should
    be interesting as both are cheaper than the truck
    and I have about $1,000.00 worth of "add-ons" on
    my truck. Good luck and keep us posted, Thanks
  • ovalleyovalley Member Posts: 135
    It sounded like to me that if I had receipts, GM would reimburse me for add ons. The windown tinting I did myself. Cost me about $14. Don't have a receipt. At this point don't really care.
    GM has verbally agreed to reimburse me for my payments to date and the value of my original trade-in on the sales contract (too low but they can't and won't change that). I am not getting charged for mileage (about 6200). So I guess I did okay, just took 5 months and a lot of my own time. Waiting of the official offer letter, hopefully today. Then about a week to get check. I'll let you know more as it happens.

    Glad to hear there is no mileage hassle for the buy-back option. The svc mgr at my dealer has informed me that a GM engineer came to their shop and supervised the replacement of front hubs and rear springs on a 99 with the same vibration problem I have, and it was not successful. Spoke with my Customer Rep. at GM and was told that, in the event that no acceptable fix is found, a vehicle swap could be arranged. I'm up to 10,000 miles and counting. I'd gladly accept a comparable 2000 model for comparable price. Sorry to hear that some folks are getting dealer flak. Mine has been pretty straightforward and admitted the problem was known w/o hassle - after we had gone thru a lot of wasted tire service.
  • ovalleyovalley Member Posts: 135
    I got my "official" offer letter yesterday. Signed it and faxed it back to GM. They tell me the dealership where I bought it would get the checks and paper work by the end of next week. Can't hardly wait! It's almost over.

    well I realize its been a while since I was on the board,,,, No new news, no good news, no fixes, and no future in trying to figure it out.... I have worked my fingers to the bone to make shake, rattle, and roll repairs,,, I have gotten to the point I cant feel the customers problems anymore, and with most customers reading this board and listening to all the complaints the majority of you all are having. they are just expecting there vehicle to have these problems weather they do or dont they want it fixed,,, I dont mean to sound off like this but I cant get gm to work with me anymore I keep getting the standard dont do anything till we come up with a repair,,, I have to this point replaced 100 hubs,,, adjusted 40 rack and pinions,,, installed 7 sets of leaf springs I lost count of all the tires I have replaced and balanced over and over again, reflashed at least 200 pickups and never get the same problem twice I have gotten to the point that when someone comes in with a vibration I put it on my lift, adjust the rack check hubs and order leaf springs and reflash the puter,,, I used to do it cause I was making people happy now I got people coming in and all they say is my friends truck does this mine hasnt yet but it will can you fix it before it starts.... thats pretty bad guys...... I have had my [non-permissible content removed] reemed by about 40000 people who have problems with there vehicle and frankly I am tired of it... I still answer all the email to me with all the knowledge I have and or can get my hands on... so keep the email coming and I will respond to all of them... I some times wish I was a maytag repairman hahahah. sorry for sounding off especially since I havent been on for a while,,,, I will try as usual to keep everyone informed about repairs,, and yes the problem did fall off onto the 2000 trucks,,, still the best buy is a 6.0 / 3.73 / auto/ with a tow package 3/4 ton extended cab pickup to date the only one with out a problem and I mean 0 problems,, no launch shutter, no tire vibration, no hub problems, no brake problems and no engine problems, 1 really well built truck I have talked long enough see ya all later Steve
  • mksalemmksalem Member Posts: 42
    wOw !!

    Steve - sorry to hear this; I was sort of thinking this might happen (truck-o-chondriacs ?)

    Anyways, thanks for your help. I've been very careful to stay away from things that aren't broken - only been to the dealer once in 23,000 and that was for the rear side window noise and a loose window track - the temptation to ask about re-flashes and hubs was HUGE but I did refrain -

    I'm sure the few that actually do have a real problem appreciate your work and I understand their frustration - maybe you can replace the hubs of some of those "time wasters" with a set of the B8 take-offs and send them on their way . . . remember, the customer is always right!

    My truck runs fine - I ain't messin' with it.
    ( that's what my wifes "exploder" is for . . . )
    Hang in there - :-)

    My '99 1/2 ton, 4x4, 5.3L, 4.10 axle, reg cab, long bed, PF9 rims, P265 Wilderness A/T's, has been very good, no vibrations. Will not let anyone touch my B8 hubs, springs or shackles, and don't have the rack and pinion. Rotated the tires and got a slight steering pull after. Crossed them to the opposite side and it cancelled. Arrow straight. Tire wear is even, and still has the factory balance weights. Whether you get a good truck seems to depend on the combination you order.
  • quadrunner500quadrunner500 Member Posts: 2,721
    I had the engine re-flashed twice for spark ping on the 5.3L, but not for rough shifting, or driveline growl.
  • sbreensbreen Member Posts: 14
    2000 1/2 ext 2wd LS SB 5.3 3.42 3k miles chrome rims.

    the bad:
    rides fine, however *sometimes* a little wiggle in the steering wheel after hitting a bump, and as soon as I notice it, it is gone. Seems to depend on the type of road I'm on. Otherwise, a good road feel. I had one rattle which I fixed myself, the metal rails that the stereo slides into made a very annoying noise, 10 mins work.

    the good:
    handles great, good power, tranny is a slick shifter, 16.5-18.5mpg, no excessive wind noise, overall a very tight feeling vehicle (really).

    This is my first full size truck (I've owned to smaller toyotas) I admit I was a bit nervous about buying a GM having no experience owning GM products and seeing some of the junk from the 70s/80s, but so far those fears are groundless, the Silverado has a nice quality feel to it. Time will tell...but for now, I simply enjoy owning and driving the truck.

    I was very close to buying the Tundra but for *my* purposes the the Toyota's smaller size (bed particularly) was a no go, and the dealer gouging was really ugly...

    Someone please tell me how to get the message center to display the "Chevy Rules!" message...love those easter eggs....
  • mksalemmksalem Member Posts: 42
    '99 ext, 2wd, 3.73, 1/2 -

    Had the same "wiggle" - went away as soon as I replaced the tires with something that had a little stiffer sidewall (and a load rating !!) - I don't think those General AmeriTrac Whatevers are up to the task for a extended cab. Rack & Pinion = no after-market steering stabilizer . . . Rats! Was yours built in Canada ?
  • chevy4mechevy4me Member Posts: 203
    I appreciate that your truck has had no problems
    but there are others that have. I like my truck but the launch shudder sucks. and I for one appreciate scraws input.
  • robertthrobertth Member Posts: 7
    SCraw...You pointed out that the 6.0 3.73 Auto 3/4 ton ext. cab with tow package hasn't had the problem. Does that go for long bed and short bed, and 2x4 and 4x4?

    I'm looking at getting a 2000, 2500, extended cab, 4x4, long bed, LT. Is there anything there that would intersect with the problems you've seen?

    Thanks for all you've done for the truck lovers out here.
  • sbreensbreen Member Posts: 14
    built in indiana, i believe, on 8/99.
    not trying to "run it in" that i've got a "good one" just trying to let folks know that the problems are present in "every" truck.
    sounds like scraw/steve has quite the fan club here, helping folks out, going above and way beyond.... pass the hat, we need to buy this guy some suds...
  • lis7lis7 Member Posts: 5
    I wish you all much luck with your 99/2000 trucks. I almost bought one last weekend: a black 2000 2WD Ext. Cab. Silverado LS with the 5300 V8 motor (beautiful truck). Boy am I glad I didn't get stuck with this GM screw up. Thank God for the internet and Edmunds Town Hall discussion. You people have saved me much grief and a lot of money. I just want to say "thank you." I have been a die hard Chevy person all of my life and will never settle for a Ford or Dodge (not that I have any qualms with them, they are good vehicles too I just want a Silverado). My family has had nothing but GM vehicles and we always had a Chevy truck in the driveway when I was growing up. I presently have a Victory Red '92 Chevy Silverado Shortbed, 350 (5.7L) V8 that rides like a dream and is not bothered by any kind of bumps and the steering wheel doesn't violently shake at 65 mph or at any speed I want to drive it. I have test driven about 3 of these new ext. cab shortbed Silverado trucks (99 and 2000 models) and each one vibrates at a different speed. One of them vibrated at 60 mph, one at 65 and one at 70. I think I am giving up on a new Silverado. As far as I'm concerned until GM decides to acknowledge this problem and fix it, they can keep the new Silverado they call "The Truck". I'll keep my old faithful '92 and feel very blessed that I have it. It's really a crying shame that such a beautiful truck with such great exterior features, roomy interior and excellent power is worthless because of a vibration problem. Do any of you think we could get GM's attention if we somehow got this on 20/20 or 48 hours or some other media program?

    Lis7,
    I too have been a die hard Chevy fan all of my life. And I too have been very ready to plunk down $26,000 to get the new Silverado of my dreams. It is an awesome truck!! If it weren't for all of the "first year" problems that this truck seems to be having (and now I'm seeing a carry over into the 2000 model) and the 4th door on the extra cab not being available yet, I would have been a happy new truck owner a long time ago. So for now, I'll have to stick to my regular cab '89 Silverado (106,000 miles and going strong, but I can't get 2 adults and 2 kids in it)!!!

    As far as getting GM's attention, well since they have a strong case of what doctors call "cranial-rectal inversion" (head up their [non-permissible content removed]), I doubt it is possible. But hopefully low truck sales will hit them where it hurts the most.... in the pocket book. Now maybe that will get their attention.

    The Word on the Street: There may be some new job openings at the GM Engineering and Vehicle Testing facility soon. Experience in "real world" design/testing and an understanding of what consumers really want is HIGHLY DESIRABLE.

    Tommrow wil be the 4th time my '99 GMC 2wd, Ext. Cab 4.8, Auto will be to the service dept for the following major issues with no resoulution:

    - Shudder on take off
    - Vibration at 60+ mph
    - Throttle sticking at tip in
    - Rear passenger window leaks air at +65 mph

    Other minor issues:

    - Front passenger seat belt "locks"
    - Window rattles in down position in passenger door
    - Excessive wiggle in chassis and body after encountering a bump
    - Driver side switch for passenger window works intermittenly.

    Oh Joy...maybe I should have bought a Ford.

    My Z-71 has a slight steering wheel shake/shimmy at around 65-70. The strange thing is that it does not happen all the time. One minute no movement at all, next minute the shaking starts. I would seem to think it is not a wheel balance issue. Anyone have any luck with adjusting the preload on the steering box?
  • cfunkcfunk Member Posts: 13
    Thanks for the window update. I will know on Tuesday if they can figure it out.

    Any recomendation on some affordable LT tires?

  • ringdalringdal Member Posts: 4
    I have a dash rattle coming from the right side of the dash,well at least I think its the dash anyway. The noise starts at about 40 MPH and gets louder the faster you go. I have gone through the glove box to try to find it with no luck.I taped any thing loose under the hood tight,with no luck.I had my window strips sealed by a glass co. and taped them to be sure,I still got the noise.I had it to the dealer three times.HELP!If I can get rid of that noise I will love my Chevy Truck. Thanks Rick

    Is it only when you hit bumps?...or all the time?

  • ringdalringdal Member Posts: 4
    I get the dash noise any time after about 40 MPH even on smooth roads. Rick
  • mgdvhmanmgdvhman Member Posts: 4,157
    Like a vibration caused noise?
  • quadrunner500quadrunner500 Member Posts: 2,721
    Adjusting the pre-load on the steering box on 2wd trucks is something Steve Crawford mentioned as being successful in curing steering wheel shimmy.
  • planejaneplanejane Member Posts: 167
    After reading your (lengthy) posts, I must tell you that your fears/or for lack of a better word.. reluctance leading to a NO-PURCHASE is understandable.

    You have every right voice your opinion and buy or keep whatever you would like. However, please understand, expecting 100% perfection out the door is acceptable, not buying a gorgeous, brand new truck of ANY KIND because of your reasoning is too much.

    If a person wants a vehicle that's a few years old, fine, used vehicles will need work too sooner or later (vehicles need work-sooner or later). If you want new, you ought to expect some minor fixes - some trips to the dealer, throughout the course of your new ownership.

    I know some have been thoroughly frustrated, but most would opt to keep what they have once its good again.

    I have some minor problems (X my fingers) hopefully no more! But when I get up in the morning, I can't wait to get into my shiny, sparkly NEW Silverado 3/4 ton - it sure beats my 1992 Chevy any day.

    So, lighten up, hon! Go get yourself a nice new truck --- Dodge, Ford and everyone else has problems too!

    I LOVE MY SILVERADO..... Cindy ;-)
  • lis7lis7 Member Posts: 5
    Hi Cindy:

    Thanks for responding to my "lengthy" post. You are right, I am very flustered over the quality of the new truck. I wanted one really bad. Notice I used past-tense "wanted". I glad that you have a new truck and that you are enjoying it. I'm happy for you. My 92 has been back to the dealer twice in the eight years I have owned it, once for a new oil pressure gauge and once for an oxygen sensor and that has only been in the last two years. My 98 Ext. Cab has never been back to the dealer for anything. It seems these new ones are at the dealer all the time for a multitude of problems, the main one being the vibration that GM has no fix for. Now I'm hearing about 5.3 engine ping. I think GM has the right idea but it needs some major tweaking. I don't have $27,000 to spend on a truck that has these kinds of problems so I'm going to just sit back and wait a year or two and see what, if anything, GM will do. I realize that there is no vehicle on the face of the earth that is "perfect". Anything mechanical will fail at some point. Some people have been lucky and have no problems at all. I sincerely hope you are one of the lucky ones. Again, good luck with your new truck.

    Lis7
  • jed1894jed1894 Member Posts: 337
    I think you're exactly right: wait until GM works out the problems. I am one of those who could not wait (did not do enough research also) and went ahead and bought a 2000 Sil. ext. cab. 2wd. I've been back to the dealer five (5) times and only 2000 miles on vehicle. My problems range from vibration, rear window noise, dash vibration, and launch shutter. And that's at 2000 miles. I am chevy person and will probably just live with the problems if the dealer can't eventually fix. Ironically, I sold a perfectly good truck for this new one.

    If I had it to do all over, I'd wait until 2001 or 2002 models, or buy different brand. It's very frustrating traveling back-and-forth to a dealer when they don't have any idea what's wrong (vibration) with the truck. Trying new tires this week--they're running out of things to replace.

    I know I'll probably get bashed by all the Chevy guys on the net, but it's very hard to once a week to drive an hour to the dealer once a week.

    This truck definitely needs more engineering attention from GM........
  • mikey42mikey42 Member Posts: 28
    is it so bad to be dangerous ? I mean its a truck after all, my old truck vibrated and shimmied so bad that I hated driving it long distance but I did. Its a truck, not a luxury car. My 2000 Ext Cab only has 600 miles on it so far and I am amazed at how perfect the truck is. But like my wife said last night, maybe your truck is vibrating and you don't notice it since you expect it from a truck.
    Maybe bad things will happen after I have a few thousand miles on it, I hope not. And so far the only reason I have been back to the dealer was to buy an oil filter so I can change the oil tonight, I know I should have changed it at 500 miles but I was out of town.

    If it was not for a place like this...we would not even know about this stuff...and buy one...and probably be one of the 99% that have no problems at all. Overall....they are very good. If you knew everything about all the world..and all your food..you would never go outside or eat again. get real...buy a truck...chances are you will not be the "one". just stay away from 2WD 3:42 Ext. cabs...or better yet...get a 3/4 ton Like Me and Cindy.

  • dch0300dch0300 Member Posts: 472
    Lis7,
    I can agree with the fact that there is no "perfect" vehicle, however before I spend $27,000 on a truck that I want to last me 15 years, I would like it to be fairly close to being perfect. And that is one of the reasons I will never by a "first year" model. Just too many "bugs" to work out.

    So with that, I don't dislike the new Silverado enough to go buy a Ford or Dodge or even an import. It just has too many nice things about it. But the way things are looking so far, I might be waiting until the 2001 Silverado is available (that is if they have a 4 door ext.cab by then. I must have room in a truck for 2 adults, 1 three year old son , and 1 new born daughter).

    Maybe we should start collecting specific data from as many new Silverado owners as we can find. Get specific data such as.....
    Year
    Model
    Assembly Location
    2wd or 4wd
    Reg or Ext cab
    1500 or 2500
    Auto or Manual transmission
    Suspension package
    Axle ratio
    Engine size
    List of problems encountered on their new truck

    If we can get enough data, maybe we can find a common denominator that is causing these 'bugs" (for instance, maybe parts or trucks built at a specific location have the majority of the problems).

  • mikey42mikey42 Member Posts: 28
    you say stay away from 2WD 3.42 Ext. cabs ? Mine is 5.3L 3.42 Ext. Cab 2WD and yeah, I ONLY have 600 miles on it but I still have no complaints. Thats why I asked how bad is the vibration, is it something you have to look for, in which case get over it its a truck. Or is it so bad as to be dangerous, I have seen a description of the vibration yet.
    mike
  • mgdvhmanmgdvhman Member Posts: 4,157
    That seems to be the combo that gives the most problems for shaking....if yours is fine...that's great. see..not all have the problem.

  • bezojrbezojr Member Posts: 11
    I bought a 99 Silverado Xcab 4.8 3.42 in May. it vibrated from the beginning...it has launch shutter from 1-20 mph and a pronounced vibration from there up. the dealer has replaced 5 tires, turned the front rotors replaced the drive shaft and it is still vibrating. they now tell me they want to replace the front hubs (not sure how or if they know they are b8 or b9) aside from the main problem the vibration has vibrated the locking mech. in the drivers seat out.....the power window regulator in the passenger door loose and probably caused the rattles or vibrations in the dash and drink holder. My point is in the 6K I have driven this truck it has seen more like 60K of wear...10X ? yeah, I believe it. I wrote my Lemon Law letter last week, We'll see. at least some of you had your dealer talking about it, mine won't admit its a problem.
  • andrewkandrewk Member Posts: 59
    Has anyone had a vibration coming from the rear end when braking over moderate bumps at moderate speeds? It seems like the abs might be kicking in, but the vibrations are tremendous and can be felt throughout the truck all the way up through brake pedal pulsating.

    I have the "regular" vibrations that so many have spoke of. I called the dealer again to take it in and they were going to take it out with me to see exactly what the problems were. When I got there, a different service tech said that it wasn't necassary because he knew the symptoms all too well. They are going to keep for a couple of days to try to figure it out. He spoke of some special hydro-balance that some specialty shop was going to do.

    A side note... they gave me a loaner/rental to use. It was a '99 Silverado that has the same vibrations and windshield trim rattle as mine, except worse!
  • dennykdennyk Member Posts: 2
    I plan to order a 2500 4x4 long bed, regular cab,
    with the 6.0 Silverado soon. Are people
    experiencing the vibration problem with these
    trucks as well? Any other problems I should know
    about? The Chevy dealer told me Friday that Chevy
    had a nationwide hold on producing long bed trucks.
    Is this because of the vibration or some other
    problem.....they did not say. Thank for the help!
  • vince4vince4 Member Posts: 1,268
    They had a 3% constraint on LB when I ordered mine but in a week the order was accepted. So go ahead and place the order, don't worry about what you hear because it changes so quickly. I think the short supply is because they expect the vast majority of sales to be ext. cab SB and plan production around that. From reading this board it seems your combination (same as mine) doesn't have the vibration problem.
  • ovalleyovalley Member Posts: 135
    Just my two cents worth. I had GM voluntarily buy back my my 99 reg cab 2wd, 4.8 L, 3.42 rear with locking diff because of vibrations. I really liked the GM trucks. Ended up getting a 2000 GMC ext cab 5.3L with 3.42 and no locking diff just last night.

    I have driven over ten ext cabs in the past couple of weeks with various combinations of drive lines, mostly 2000's, a few 1999's, 3.42 vs 3.73, both with and without locking diffs, at various dealers. I liked the feature of the locking diff, but every one I drove had the vibration at speeds over 60 MPH (both 3.42 and 3.73). The ones without it did not (both 3.42 and 3.73). One 1999 had very noticable launch shutter and play in the rack and pinion. Once I decided to give up the locking diff, I had no problems. The trucks with locking diff had the Firm Ride susp most of the time and the ones without locking diff had Smooth Ride susp. I'm not sure what the common factors are, I just avoided the locking diff rear and I found no vibration problems.

    When I drove these trucks I did not just take the salesman's preferred route. I got it out on a smooth stretch of road at highway speed and drove it for a while. Good luck to those who want the locking diff rear end. Be sure you test drive any truck you decide to buy before the deal is done. The dealers are generally very hesitant to fix a truck before you buy it.
  • marcmarc Member Posts: 21
    The dealer updated the computer for the vibration at 40mph, Now it seems that it has a constant vibration no matter what speed I am going.

    I still have the clank when going from D to R, sounds like bad u-joints.

    I have a clank when going over speed bumps or small dips in the road. Not sure what that is.

    Now, I have an oil leak from around the rear main area. That's the last straw!

    The worst part is, 1/2 the time the service manager tells me they can't dup the problem.

    This will be the 5 time I will bring it in. If it is not fixed this time Lemon Law and Ford hear I come.
  • wroberts2wroberts2 Member Posts: 1
    I have two problems with my 99 silverado--
    One is a problem with a vibration. The vibration
    is bad enough to shake the whole truck- The local
    dealer has done everything they know how including
    putting a new drive shaft- None of this helped-
    Second, there is a rubbing sound in the front end-
    The springs have been changed out and several other things-- All they have done is change the rubbing sound to a squeek--
  • planejaneplanejane Member Posts: 167
    If this helps, I have a 99 3/4 ton with 3.73, Locking Diff and Firm Ride suspension, and it does not vibrate.

    Tim,
    You are right, all this talk does make a person paranoid about their truck. Most who don't read Edmunds would not be aware of some of the problems. I drove again yesterday with no radio on just listening for ????? Every time I get to a stop light and someone else's brakes squeal, I keep thinking its mine.

    There are a very few lucky people out there who have the 5.3 Ext. Cab. with the 3.42 rearend (99's and 2000's) that do not have any problems. You should consider yourself very fortunate to be one of the lucky ones. It does seem that the vibration problems are most common in this particular model, however some are reporting it on the 4x4 ext. cabs. I drove 3 2WD ext. cab Silverados when I went to buy a new truck and each one of them had a severe vibration. The 2000's had it at 65 mph and the 99 had it at 70 mph. I drove one 2000 4x4 ext. cab and it rode like a Cadillac (about like my 92 and 98 Silverados ride now). Now, you would have to be numb from the neck down not to feel this vibration. On the trucks I test drove I let go of the steering wheel at the speed it started to vibrate to see how bad the vibration really was and to make sure it wasn't just me TRYING to find something wrong and I was startled to see the steering wheel violently shaking. In my opinion, I do believe some of these trucks are dangerous and should not be driven on the road. Bumps and uneven road surfaces seem to aggravate the vibration even more. It almost feels as though you are about to lose control of the truck. I don't think that's safe at all. I have owned 6 Chevrolet trucks so far and I have never experienced anything like this. No, trucks do not ride like cars and you can expect to feel some bumps in the road and maybe bounce a bit but not a constant vibration or shudder. I don't know what it is but I know it ain't right and I hope GM gets it worked out soon.

    In the Tundra, when they were reporting steering wheel shimmys, one of the fixes mentioned was that the factory would replace the steering wheel with a heavier one, to dampen the movement. Which brings to mind the point that this appears to only be happening in 2wd trucks, which have a different steering box mechanism, rack and pinion. The 4wd trucks have recirculating ball. Seems like what would help, mentioned earlier by someone else, is a hydraulic steering dampener fitted to the 2wd trucks with the rack and pinion steering. Or someone with the shimmy could try taping weights to the steering wheel to see if there is any validity to the earlier point. Also mentioned was going to stiffer sidewalls from truck tires versus the softer flexing passenger car tires.

    Thank you for the description, I now know what people are talking about. Its not a minor vibration that one can ignore, its a major one. And my truck does not have it but after last nights drive, it only has 680 miles on it so who knows what will happen.

    2500's do not have any problems.....as farr as I know. I believe the biggest problem with the 2wd Ext. cabs is the 2 piece driveshaft. getting the two pieces together just right is a trick in itself I guess.
    As I've mentioned before...the shaft on the 3/4 is HUGE....gotta be 7 inches in diameter or so....that puppy ain't bending.

    Good Luck to all

    Just a note on the 2 piece drive shaft:

    According to a very good service tech. at a Chev. dealer --- The 2 piece drive shaft is a source of launch shutter. He said if the drive shaft was off (angle at joint), it would vibrate at most all speeds. He explaned that the seat, dash, and everything else would vibrate very fast, more like a hum. He said the old s-10 ext. cab. models had same problem. The cure was drive shaft angle adjustment.

    That's what he said. I wouldn't know a drive shaft from a trailer hitch.

    I had the "clank" going over small bumps,
    I have a 99 xcab Z71 with the 4.10 posi. Dealer
    replaced rear springs after several attempts to
    blame it on other things, this has stopped it for
    now. Also had the clank noise when shifting from
    P or R to D, they put in an anti-clunk seal/spacer
    and that helped for awhile but I have noticed the
    noise when I pull away from a stop or at low speed
    shifts from 1-2. Will be going in again on Monday.
    Talked to service rep about trans reflash, had no
    clue what I was talking about. Said he has replaced 4 sets of springs, 2 worked, 2 didn't.
    Have been talking with salesman ref "buyback"
    they have already bought back a 2wd ext cab. Still
    attempting to get windshield mouldings to stop
    slapping and 3rd door 1/4 window wind noise to
    stop. Been seeing alot of used 99's in this area
    on lots.

    A friend said I should have them check my fly wheel for a crack or a spot weld being broken. I am not sure exactly what he is talking about but I talked to 2 people that said they had the fly wheel problem that caused the clank when shifting. It would only happen every not and then because only when the broken spot weld was lined up would you get a clank. It was on older GM trucks, I am not sure what year or what spot weld they are talking about.

    Does this make sense to anyone?
