    Well I have not recieved all my paperwork yet on the exactly what they did. Apparently they have to get it all sorted out first. anyway, From what they could tell me they rebuilt the whole txf case and stuff. Said that the gears were all tore up. I dont have more specifics yet but I will post when I find out.

    So far no noise. My rotational noise came when in 2hi, 4hi, auto. I could hear it alot when I slowed or accelerated.

    Thanks for the input hunter.

    There is a TSB on the front Differentials that has to do with the engaging mechanism. This is an old TSB where due to a partial engagement the carbon fiber discs in the front diff would be worn out by 2wd driving. Then when you command 4wd the discs would not engage.

    Here is some of the text of the TSB...

    Front Wheels Slipping with Vehicle in Four WHeel Drive (Replace Transfer Case Clutch Plates and Front Drive Axle Lubricant) #99-04-21-003B
    Front Wheels Slipping with Vehicle in Four Wheel Drive (Replace Transfer Case Clutch Plates and Front Drive Axle Lubricant)
    1999-2001 Chevrolet and GMC K and T Models (Silverado, Sierra, Blazer, Envoy, Jimmy)

    with NV236/246 Transfer Case (RPO NP8)

    This bulletin is being revised to correct a part number in the Parts Information section. Please discard Corporate Bulletin Number 99-04-21-003A (Section 04 -- Driveline/Axle).

    Condition
    Some owners may comment on a slipping type condition at the front wheels while the vehicle is in four wheel drive (4WD).

    Cause
    When the vehicle is driven extensively in low temperatures (-12°C (10°F) or below), slipping may occur when the vehicle is in the 2 HI mode. This occurs because the transfer case clutch pack does not have enough torque capacity to overcome the viscosity of the front axle lubricant. The friction generated by the slipping clutch discs may cause premature wear of the clutch pack assembly.

    Correction
    Overhaul the transfer case and replace the clutch plates on affected vehicles. Replace the lubricant in the front drive axle with synthetic axle lubricant, P/N 12378261 (in Canada, use P/N 10953455). Use the following procedure and the part numbers listed below.

    Thanks for the TSB info. I think this is what they had to do. I am still waiting for the paperwork. I have the truck back now and it seems to work great. I suspect that will change since I own a truck huh?! Just a matter of time.

    FYI. "carbon fiber discs in the front diff"

    The carbon fiber discs are located in the transfer case!
  • I had a 99 5.3 Sierra and never had an engine knock but did have what I always thought was a lifter noise when starting cold that went away before I was out of the garage. Just bought a 2003 Rado z-71 5.3 and now I am worried about this engine knock stuff. Its got about 4k on it now and still quiet.
  • chevy4mechevy4me Posts: 203
    I had one replaced under waranty but its progressivly getting louder again. Is there a TSB on this problem?
  • Hi all,

    Is there a way to disable the Automatic headlight feature on my 99 GMC sierra truck. I have tried the dome override trick,but that didnt' work on my 99. Please help. thanks!
  • I'm looking for a hard Tonneau cover that is removeable. So far the best option I've found is made by Peragon. Does anybody have any experience with this or any other hard Tonneau covers? I had an A.R.E. on my last truck and while it looked very nice, it was very difficult to remove.
  • rayt2rayt2 Posts: 1,208
    My Y2K override feature works fine , push dome light button in 3 times and it cancels the auto feature. It resets everytime you restart the truck however. I thought 99's were the same way, maybe not.

    are heavy enough that it's pretty much a two-man job to remove them. I had a Snugtop that fit great. It had two pins in the hinges at the front that pulled out, then after unhooking the struts cover would lift off. I never actually took it off while I had it. The one I have now has tabs at the front on the underside of the cover that slip into slotted pieces that mount to the front of the bed. So you have to open it, unhook the struts then lift it open farther as you slide it back out of the slots. Not something you want to do too often.
  • Try Gaylord's in Bellflower CA. They have dealerships in various places. Theirs works very much like the Texas Yankee just described. Little tough for one person to take off, but they are strong. I just walked all over mine and it didn't give a bit.

    Check out www.lightsout.org
    Easy and FREE advise to turn off those
    PIA auto ons and DRLS............geo

    BTW: 99 and some early 2ks Do not have
    the override feature by pushing in the
    button 4 times........

    I have an ARE and would have to say it is one of the better ones available. Being that it has the clamp-on rail helps to make it somewhat easier than most since you don't need to do more than remove the four clamps securing it to the truck. At times I would rather have a cover like a Truxedo, but I like the security of the hard cover, since GM has yet failed in providing a locking tailgate like the rest of the manufacturers.
  • sonjaabsonjaab Posts: 1,057
    There are a few aftermarket companies that
    sell replacement locking tailgate handles.
    Its funny tho....'Lades, Tahoes, etc have the
    same handle with a lock in it. Iwonder if they
    would fit a pick up ?...............geo
  • ricschricsch Posts: 540
    I'll have to check that out, not sure how difficult it would be to convert the handle to a Silverado. Would have been nice if GM could have had an access panel on the inside of the tailgate.

    Picked up the new '03 last night-steering wheel radio controls are nice, as is the auto dimming rear view mirror. Otherwise not much different from my '01, other than it being a 4x4.

    Wish Chevrolet would have went with the smooth talgate guard on the 1/2 tons like they have done with the 3/4 ton trucks! I'll have to get out the drill and remove the blind nuts to install the smooth one to use my hard cover.
  • Just what noise does it make. My Rado Ac makes a strange sound like a sighing sound at about 1800 RPM.
  • I had a 99 GMC Sierra and the dealer had to de-program the auto lock doors, you might check with a dealer and see if they can't shut off the auto headlights too.
  • sonjaabsonjaab Posts: 1,057
    Visited the Chev-GMC dealer yesterday. They
    had about 100 new 03s.....Some of the 1/2s
    had the new style whaletail. It wasn't straight
    across the bottom. Itwas like notched out between
    the bolt holes. Others had the 2500 style flat cap.

    RIC: you can take off your waletail...Make sure
    you get a genuine GM flat one from dealer. It
    will cover the bolt holes in gate. My bud took
    his off because of clearance probs. with cap.
    We tried the other caps from autozone etc. and
    they didn't hang down low enough to cover holes
    in tailgate but the GM one did. NOTE: all new
    GMs have he holes already in the tailgate
    anyway !.........geo
  • I have a 2000 Silverado 1500 Ext Cab w/5.3L V8. I have been experiencing several problems that I could use some help with. I do not have a dealer in my town to bring it to. I am hoping some of you have had the same things happen and can shed some light on things. I would really like to find a site with a knowledgeable GM truck mechanic I can access. Here goes:

    1. The "Service Engine Soon" message light is on
    constantly. I found a local shop who took a
    scan tool, found the faulty code (EVAP SYST). I
    had them clear it, which they did. Light came
    back on 2 days later, still on. Any clues?

    2. This may be related: Now that it is cooler out
    (I live in Alaska), I have noticed my
    defroster output is weak. No mater where I put
    the selector, nearly all the output is on the
    the floor. I am guessing the selector is vacuum
    operated. Anyway, I get a ton of hot air when
    the engine is warm at the floor vent, but it
    is not diverting to the defroster vents at the
    windshield.

    3. On several occasions, the display on the radio
    cd unit goes out. Heres the wierd part: The
    radio will play, but nothing else. Even wieder,
    you CANNOT shut the radio off. Pushing the
    little orange button does nothing. A day or two
    later, it all comes back to life and works
    just fine. Ideas??

    4. I read something here some time back, but when
    it gets cold out (below 10 degrees), the rear
    cab doors won't latch shut. REALLY slamming
    SOMETIMES does it, but not always. Gets worse
    as it gets colder. Is there a fix out for this?

    Would appreciate hearing from anyone experiencing
    these problems. Would like to get them ironed out.

    Thanks,

    Frostbit

  • I have a 2001 2wd 1500 ext cab Silverado and want to know if 265/75R16 tires will fit with out rubbing?
  • obyoneobyone Posts: 8,065
    is 275/70R16
  • 1. There are about 5 different error codes for the EVAP SYS. Which code did the scan show? You could have a vacuum leak, a bad purge selenoid, etc.

    2. I have had experience with the selector switch not working. I have seen dead shorts in the mode actuator door, and no signals from the control to the actuator. About the only fix is to replace the mode door actuator and/or the control module.

    3. Have no clue as to the radio. I have never come across this.

    4. The latches on the doors either need adjusting or replaced.

    3rd and 4th Door Hard to Close When Cold (Replace Latches) #00-08-64-016
    3rd and 4th Door Hard to Close When Cold (Replace Latches)

    Condition
    Some customers may comment that the 3rd or 4th door is hard to close when cold.

    Cause
    There was a change to an internal bumper in the latch and the removal of the primary door seal internal plug.

    Correction
    1. Verify proper alignment between the upper and lower striker before proceeding to the next step.
    2. Replace the upper and lower latch assemblies using the part numbers listed below. Refer to the Doors sub-section of the Service Manual.

    3. Remove the primary door seal internal plug across from the lower latch assembly.

  • after 37,000 on the O.E.M. Tires , bought the Good Year Forteras.........HUGE mistake.

    truck started to vibrate / shake and has not stopped after (2) sets of Forteras and (8) re-balance and even high speed on the truck balance. Installers / shops....GoodYear (2 different ones) - Sears - Performance shops - Specialty shops, all find that the tires are hard to balance.. The vibrations are less than in the begining, but at this point I am ready to throw these tires in a dumpster. Wish I had kept my worn out tires.

    Reminds me of the 99 Shakerado I had for 10 months.....it is hard to be a chevy fan.

    forgot to mention, not starting 3 times for no apparent reason. Last time was Thr. 10/31 while on the way to a crucial meeting. Never make a stop before crucial meetings. Dealer on the phone was usless. So I opened the hood, then the air box........turn the key, it started up with no problem. Closed it and hauled as..........s

    you said "it is hard to be a chevy fan."

    You are having a tire problem correct? Thats not a chevy problem that is a tire problem

    Id say its hard to be a goodyear fan!

    Do you know why the 2wd Silverado is limited to 275 70 16 size tire? I have 285 75 16 on my 4x4 Silverado and plan to put these (wheels and all) on my 2001 Tahoe 2wd for a trip to Colorado next month. The Firestone Wilderness LE's on the Tahoe don't look like they would be worth $.02 in the snow.

    I have eye balled it and IMO the 285 75 16's will fit on the 2wd Tahoe without rubbing. The 285's are less than 1 inch wider - I don't see how an extra 1/2 inch on each side will make any difference.
  • the reason is , there is always something screwed up.........currently 2000 Silverado xcab 5.3
    1. Steering wheel leather finish started peeling, replaced by dealer
    2. Sticking throttle body, fixed
    3. Wandering on the highway, 18 wheeler pass you and you gotta to hold on with both hands......fixed after 5 shop visits for alignments
    4. Headrest came apart, fixed
    5. Headliner came loose at the rt door, fixed
    6. Outside mirror shakes when on the highway, rt side real bad...left side not so bad, dealer said To Bad So Sad Throw Away The Bug Shield.
    7. Rear rt brake cable holder came loose, fixed
    8. Head rest came apart....again, out of warranty
    9. Security light comes on for no reason......passlock changed, same results...dealer can't fix..
    10. Rattle in the dash cup holder, dealer replaced.....now it squeakes
    11. DRL burned out twice
    12. Backup bulb buned out
    13. Click sound ( like a switch ), when stopping and accellerating, from rt side
    14. Driveline clunk....4 visits for lube to the shaft, now fixed since I stopped going through the "Touchless Carwash"
    15. Rear springs sagged after 3000 miles, without carrying a load, tail end dropped 2 inches, dealer advised "within specs".......fixed when I had air bags installed.
    16. ****** Cold start knock, everytime you start up...now last for about 5 min
    17. New tires and all hell breaks loose......nahh it's a chevy problem made out of cheap steel
    ( factory springs made in Mecico ) and low quality parts that causes a lot of down time for a truck that is so wimpy.

    But then the 99 I had was even worse.....42 days / 17 visits, that were logged, to the dealer.

    My daughter would not even consider a Chevy for her 1st new car after driving my 1985 Toyota. Like I said, GM is making it hard to buy domestic.

    Sewel Chevrolet Sucks!!!
