I bought a new 98 Z71 extended cab with all the bells and goodies I looked at the new 2001 yesterday and will be ordering the best looking and performance is great best for resale and best all around truck on the market bar none.An other Z71 yea a mans truck with a lot of class.All the people that own dodges and fords Chevy wantabe check and see what your used truck is worth after 2 years compared to Chevy. hehe..suprise...Chevy is on top.dodge and ford. are in a race to look alike when the look has been around for a long time with the mack truck hehe. thanks EL
I too have a 00 silverado with the same shimmy as what seems to be everyone else. Usual fixes have been tried with no success. Arbitrator now says they have until March 20th to refund my money. It is a sad day-----forced to buy a ford---no power, less mpg and less room all for more money----doesn't shake the coffee out of your cup though---some savings there!!! I hope GM gets this right soon----I may never go back
I have the 60 to 70 vibration. My truck is 00' reg cab short bed 2wd 5.3 auto 3.73 locking diff. My truck has had pretty much all the things done to it that everyone else has had. The only thing that helped me at all was putting on Michilins in place of the generals. But I still have the vibration/shake. I do know what is wrong with my truck,the drive line angle is wrong. If my dealer had a half smart tech he could adjust it and probably take care of it. but I just got the OK to have it bought back so--. But I think what I have found out my be of interest to some. I live near Lansing Mi. and there is a large car hauling company located there. My freind who from time to time visits this location for buisness told me about a year ago that he spotted a memo posted to the drivers that they were over tightening the chain down on Silverado pickups and bending the frames. This was before I even thought about buying my current truck. At the time I did not think much about it. My thought now is why is my drive line angle off? what could so many trucks have in common but yet so many are ok? A bent frame in transit could certainly change the drive angle enough to cause the minor vibration that so many of us are having. And the amount that it is bent would probably vary so that would explain why the vibration is different in magnutude from truck to truck. Now I realize that some problems are different, like the trans programing or the launch shutter but if you have the high speed problem then you may want to have your frame checked. I am shure GM knows this but here is the catch, If you have a bent frame then they would probably have to replace the vehical. since straightening it could soften it and in a accident be a leagle issue.
As an added note to post 498, when I ordered my 2wd ext cab 1500 series in Oct.,I asked the dealer if he had seen the Edmunds bulletin board on vibration problems. He wasn't familiar with it but he did say that the only problems with the new trucks was that some had been damaged in shipment. My understanding from him was that the tie downs in some cases had been incorrectly attached to the frame. He did not comment on what was done with these damaged trucks... My truck is a pleasure to drive. I have no complaints at 2500 miles....
Can't help but wonder if you guys aren't on to something with the steering system/gears/sensitivity. Yes I drive a 1999 F-150 and even with the 17" tires it is very nice and smooth. But personally feel like the things that go wrong with any of our American trucks could happen again - like to keep an eye on it. Even with Toyota's new Tundra (or Dakota enemy) seems to me like the Dodge, Ford, GM trucks are the ones that compare with each other. Think you might have something there with the steering sensitivity, but then I think I remember a very early recall on these trucks regarding the power steering pump not properly attaching to the new frame.
Well this is nice to find out now. I got a silverado LT 4x4 ordered and its supposed to be here in about 2 more weeks. Are you guys arguring with GM dealers or do they know they have a problem with this and are trying to help you nicely so the can find the problem?
Hello everyone! I'm in the market for a 2000 4x4 Silverado with the Z71 package. But, I'm now concerned about buying this model -- because of the vibration in the steering wheel. I've been through this before with my 96 F-body (Z28)...And it was a major headache! Chevrolet did all of the same things like change and balanced the tires, Check to see if the rims were warped -- but that didn't solve the problem! In the end, it turned out to be the driveshaft design! It took a while to solve this problem -- but I was able to correct it. I really don't want to go through this again! It was like driving a paint shaker at highway speeds! One thing I noticed on the topic list -- was that it seemed to be more common (vibrations) on the 2 wheel Silverados vs. the 4x4. Does anyone know if the steering problems are on all Silverados (2 or 4x4 models)? Has anyone seen a service bulletin Yet? Are there any other problems I should know about in this model before buying it. I'm VERY loyal to Chevrolet and want to continue to driving them. Your responses are greatly appreciated.
Team2joe: Thanks for information. My service tech. mentioned the same thing when I finally fiqured I had a warped rim. He said it probably happened on shipment, etc. I didn't pay much attention until I watched them unload one. What a treat! Don't ever watch them unload a truck you're about to buy!
Bob331: Some folks are having good luck with their dealers, some are not. Some seen to be honest, some are not. I've heard everything from about five different dealers. Then another version when I filed with BBB. Who knows?
tsw4u: When I first starting posting, etc. it seemed to be more 2wd ext. cab models than the 4x4s and reg. cabs. However, I believe it has picked up with the reg. cabs and 4x4s. Seems like every model is having some type of vibration problem. You'll need to read back to be sure.
days. Instead of replacing Generals for third time, GM rep agreed to credit Generals against cost of Michelins LTX M/S 275/70HR16. Had a Goodyear dealer mount them as Chevy dealer won't mount tires on chrome rims. Long story short, after leaving GY dealer and onto freeway, right at 65, earthquake began. Truck vibrated like hell on wheels. Returned to GY dealer to rebalance tires. The tech asked me who mounted the tires and I told them that they, the Goodyear dealer did and why he was asking. Apparently, they found a tire weight on the inside of the tire which was bouncing around. I told them that I guess the Goodyear service is just as good as the Goodyear tires....Just my opinion....
How did they resolve your towing vibration problem? Also, is your new tire and rim fix still holding out? By the way, did you notice what happened to Posts 491-493? I guess Edmunds must be editting the posts? Does this happen regularly? I think 491 was a Chevy basher (his name was badass dodge) using some mild profanity (not really that bad), and I responded to him. Anyway, I don't care that they deleted mine since they deleted his post too, as mine was just a reply to him. Thanks, Ken
If a truck has no vibration during a good test drive does that mean it will proably be OK, or do these problems develop later? I've been looking for a 4X2, but may go with a 4X4 because there 4X2's in LT trim are few and far between in NH.
Generals are a POS tire. After removing the weight, the Michelins are solid. I found that a lot of the bouncing on the concrete freeway was due to the soft sidewalls of the Generals. No bouncing, no vibrations..the truck now drives and rides like a solid truck. I had a launch shudder with about 400# weight in bed. Tested this morning. That problem is now history. Don't know if this applies to everyone as some have changed to Michelins...but it worked for me. Still got those leaking quarter windows and the driveline growl.....
Truck has vibrated since purchase at 65-70 mph.Wasn't aware so many like me.Otherwise would have taken quicker and more serious action.Have 15000 mi. and General tires on factory alum. wheels.Dealer has rebalanced tires couple times and replaced rear spring shackles.Vibration will not shake teeth loose but is noticeable and passenger seat vibrates constantly at highway speed.Looking for possible solutions.Love truck,hate vibration.
kansan: yeah I noticed the edit...oh well.... also my vibration is still gone...now with about 4300 miles since new rims and tires and still no vibration. REF. the towing vibration: I don't know exactly what the service tech did but I think it had something to do with drive-line angle and re-flash of tranny, I think. After they were done, I noticed a different type shime at the angle on the drive-shaft. I also told them to check the tow haul feature just in case it had anything to do with problem. I'm going back in a couple of weeks to get a complete list of what he did.
One interesting note on the towing vibration: it still vibrates a little with light trailers, but not at all with heavy tongue wgt trailers. The trailer I use now feels fine so I'm happy.
alt4: getting a smooth ride on the test drive doesn't mean that truck is going to be okay. Some folks are saying they're getting problem well into ownership. Read back, if you haven't done so, because I'm not sure. Good luck...
Why are the tire manufacturers the last to realize that people buy and use pick-ups like personal transportation. In other words, cruising on the interstate at 80+ mph should not be a problem - at least with the tire. I have driven pick-ups for over 500,000 miles in the last 18 years and tires are the biggest plus most expensive problem. Would like to think it is getting better, don't know yet. The big 17" Goodyears on my F-150 are plenty smooth, but if they do what my last set of Michelins do when driven on hard, wash-boarded gravel roads - well, I'll know soon enough - will start having constant blow-outs by 18,000 miles and a husband telling me never to buy this POS again. So far, though I have learned to spot the problems. The rocks literally dig into the soft tread. I have watched these 17" Goodyears carefully - they are still at 75% of original tread and I don't see any rock-digs. We'll see - I am not impressed with light-truck tires - period.
Kit, thanks for your comments, but the ford (refuse to use capital letters) column is several pages over from here.Please review responses from earlier posts.
Tire problems seem to be major complaint here. Thought I would mention that I have had a lot of experience with tire problems and they can be a real problem. My point: why do they continue to be such a problem? Trucks are the main thing now a days, surely we should be able to buy round tires by now.
Truck manufacturers put a bid with minimum specifications out to tire manufacturers. As long as the minimums are met they are bought strictly on price. I guess the minimums don't require the tire to be round.
Hi all. My vibration woes are soon to be over. Notified yesterday my 2500 truck is to be built next week. Never bought two trucks in one model year before, but the trust factor was not there after dealing with vibration problem on my 1500 series Z-71. It is doing fine at 7600 miles and shake is still minimal. Body mount posting I read may well be the answer to all our problems, but, I will be expecting to take delivery of new truck in mid March.
I know this isnt the topic here but how long did it take you people that ordered these trucks to come in? I put a order in for a 2000 lt z71 4x4 ext. cab on January 4,2000. I called the dealership today and they still dont have a order # or production date. Just wanted to know if that is normal, sorry Im not in the right topic but want to keep checking these posts.
Go to Topic 816 or 1594 for more to the point answers. I ordered 12/17/99 & recieved order# same time, got TPW 1/21/00 for week of 2/7, truck built 2/9, still awaiting delivery any day now. So that makes 9 weeks so far.
....if you don't have an order # yet that means the dealer has a problem with allocation or there is a delay/holdback on certain models/options you ordered which will not allow the VOMS computer to accept your order because of these restrictions.
The dealer SHOULD be able to show you this on the VOMS order system computer at the dealership. This is what they did for me when I placed my order, I physically watched them type it into the GM ordering computer. It rejected my initial order which was for 2500 base model ext. cab w/10 options. The base truck was on restraint from factory so I went up to LS model & order was accepted while I watched & order # issued, while I really did not want the LS it was that or nothing! Go to Topic 555 post 442 for what I ended up with.
Hope this helps it was my long winded version (I do it for therapy while waiting)

(Unfortunately not me, but maybe for some of you.)
I spoke with a retired GM Repair person. (At the end of each production line there are repairmen, and he was one for 37+ years, just retired in october.)
Anyway, between the cv joint and the gear housing, there is a point where the drive shaft bolts together. There are 6 bolts there. The head of the bolts are on the tire side of the plate. Make sure they are all tight. Tht's all. (mine were tight, but hey, it was worth a try.) Evidently he had seen a few trucks that weren't tightened all of the way down.
Hi, I have a question for Obyone or anyone else, I am trading my 99 GMC Ext. Cab 4x4 SLT with 265/75R16 Firestone wildreness AT's off on a 2000 just like it with 4 doors and the base 245/75R16 tires. I am driving it immediatly to the tire dealer the week of April 1 (when supposed to arrive), and going to change the tires out. What I am wondering is first of all, how do you like your Michelins LTX M/S 275/70HR16, are they the same height as my 245's or are they like 265's, I know that they are wider. How do they compare to the Michelin LTX ATs. I am going to put on either BFG Radial All Terrain TA KOs or Michlin M/S or ATs as far as right now. I would like to at least go to 265's if not 285's on the truck in an AT tire. I couldn't see spending the 320 bucks from the factory for firestones that aren't wearing well on mine and aren't a very premium tire. Any comments about tires, changing the speedo, or what size tires will fit would be much appreciated.
the posts were deleted because we (I) got a bit carried away when the ford and dodge people started claiming to be CHEVY experts. If I offended anyone I am sorry. I will do my best not to do it again.
Post #514 above politely states how I feel about that subject!!
I now have 2500 miles on my replacement GY's and things are fine. No vibration!!
I think there are several different vibrations we are discussing here and very likely several different fixes.
To the fellow asking about michelin LTS M/S's...I have them on my wife's 99 Blazer LT and they totally transformed that vehicle into a better ride all around. The Uniroyal Laredo's came off at 10K since they had no wet weather performance at all. If the LTX's do for the Silverado what they did to our Blazer you will be pleased. I plan on putting them on my 2K Silverado when necessary....although I'm not sure they meet the "spec"??? I will go to 255 X 70 X 16 to replace my 235's. They have the same height.
Tire is rock solid. No problems. Then again I can only compare with the previous Generals which is not a fair comparison. The reason that I bought these particular tires was based on the survey at tirerack. these tires scored the highest overall and high in catagories which were important to me-wet traction, road noise, longevity. Haven't run them in the snow, but that would be rather difficult in Hawaii. I've heard that the 285's fit but rather closely. Using tirerack fitting system found that 275 would fit no problems. didn't really matter since these tires don't come in 285. Which tire you select would depend on the use. More aggressive tire AT also produces more road noise.
Because of the series difference in the tires you are comparing 70's vs. 75's, the 245/75 are about 1/2" shorter than the 275 while the 265/75 are about 1/2" taller. As far as difference in width, the 275 is about an inch wider that the 245 and less that 1/2" wider than 265. Hope this helps. Good luck. If you go to the following link, they discuss how to compare the different tire sizes:
Do any of you guys think that the high speed vibration may be caused by the rear brake rotors? My truck has a slight vibration at 70-75 MPH. Dealer forced balanced tires. Improvement was noticed. I tried raising the air pressure in my rear tires this also made quite a differance. I wonder if it possible to check the rotors for proper balance during rotation???
you can balance rotors. I know that you can have them cut/resurfaced and probably change pads while you're at it. I would think that if it was a problem with the rotors that you would experience vibration while braking. Then again there is a first for everything...especially with these new, state of the art Silverados.
You live in Hawaii, I've been half a dozen times in past twenty years and can't get enough of any of the islands, which island are you on? Your last name seems to indicate your a native of the islands. My e-mail is under profile if your up to it.
VIBRATIONS: Don't have any yet hope not to but then I need that damn truck to know for sure. Should be in by end of month I was told, another lie??? 2500 ext. cab 2WD supposedly are not experiencing these problems from all the past posts I've seen.
ROTORS?? I don't think so, you would feel it as soon as you touched the brakes if they are the least bit out.
did you see the posting by royb3 in topic #615- post #140 regarding 2500 Silverado? I think he may be the first? Seems to be going through buyback with xcab 3 door.
Thanks for the input. In trying to reduce the vibration that I feel in the rear of the truck there is also a harmonic noise. I was able to eliminate most of the harmonic. When the rear seat is removed there will be two open chambers. I placed more insulation in the chambers and more along the back wall of the cab. I did not completely fill the chambers as I think they must serve a purpose but Im not sure what that would be. At least now I dont have to listen to the harmonic noise. Without the noise produced by the vibration it actually seems like you feel less vibration. What a crock that last statement was but perception is everything.
