Chevy Silverado Problems



  • I'm not having any trouble with mine. I do have a regular cab, so the door and window issue is not applicable to me.

    Hello everyone. I'm new to the list and have a question about my 1998 5.7L Silverado. The factory warranty is about to expire and I wanted to take care of a small nuisance...a clunk in the driveline when accelerating. Also, while coasting onthe road and then hitting the accelerator, it feels like there is some slack in the driveline at times. Especially when accelerating out of a corner. Are these two things related and what suggestions would anyone have as far as getting them fixed the first time by my dealership? Thanks.

    I have a 2001 1500 XC LT 2WD 4D 5.3L, born Oct 10th, about 5,000 miles.

    -- No vibrations.
    -- No steering shaft problems
    -- No window wind noise
    -- No rear door closing problem in cold weather
    -- No other problems I can find, and I'm *VERY* picky!

    Love the truck, and especially those heated leather buckets, when the temp is -15F like it was this morning!

    I have 99 model with same problem. I know of other people with 98 model with the same problem. I think GM has a cure for the problem.........maybe someone else here can help.

    Thanks for letting me know that I'm not alone with the driveline clunk problem. Like you said, I know that GM must have a cure for this. Others of you, please help us solve this.

  • I have a 1993 MC 350. I have had the same symptoms since I bought the truck new. Got 108,000 miles on it now. I have never had a problem with my truck. I think the feeling you have, I think is normal for the tarns you have. I have had the best luck with the truck I have. Wish everyone has the same. I had to trade because I bought a new camper and needed a bigger truck to pull it. I traded it in today for a new 2500HD Crew 6L. The delivery date is 3-22 I think. Does anyone know if they meet their delivery dates. I wonder what the gas mileage will be? I have to brag a bit. I have never had to align the front end, only replaced the altinator at 60k, belt once and windshield modulator at 80k, besides brakes and oil, its been a great truck. What else could I ask for. I was a Ford guy before, but I'm buying my 2nd M.
  • I still have concerns about the vibration problem with the Silverado. Anybody know anything about the 2001's and this problem?
  • Am trying this again to make sure. I am considering buying a new Silverado, but have heard that there have been vibration problems in the past. Does this problem still exist. Any experiences to share would be appreciated.

    I just had a '01 Silverado xcab 2wd as a rental. When I had originally rented this truck in December, it had 300 miles and no vibes. At the ending of January, I rented it again. It had 3000 miles and vibrations at 60 mph.
  • obyoneobyone Posts: 8,054
    Is your truck 2 or 4 WD? Makes a big difference on the answers.....
  • jed1894jed1894 Posts: 337
    I've tested several 01 models in the last few weeks ...... I was surprised to find out that the sensitive steering and vibrations are non-existent in the one's I drove. I don't know if the problem is cured, but the trucks I drove felt real smooth. Good luck.

    The only thing I did notice....... it seems that the 01 models are smaller (inside interior). I'm probably wrong but they sure felt smaller than my 00 2wd and 99 4x4. ??????

    My truck is a 1998 5.7L 2 wheel drive extended cab. Any suggestions???

    I'm going to take a copy of your post to the dealer for work......It sounds kinda like what my truck is doing so I'll try it. My truck has the tranny clank when shifting from 1st to 2nd. The initial start from stop is not a problem. ..... won't hurt to try I guess......

    Document ID # 656972
    Info - Driveline Clunk #99-04-20-002
    Driveline Clunk
    2000 and Prior Chevrolet and GMC Light Duty Truck Models
    This bulletin is being revised to update the models section and add information to the Important statement. Please discard Corporate Bulletin Number 56-44-01A (Section 4 - Drive Axle and Section 7 - Transmission).

    The condition described in this bulletin should not be confused with Driveline Stop Clunk, described in Corporate Bulletin Number 964101R (Chevrolet 92-265-7A, GMC Truck 91-4A-77, Oldsmobile 47-71-20A, GM of Canada 93-4A-100) or Bump/Clunk Upon Acceleration, described in Corporate Bulletin Number 99-04-21-004.

    Some owners of light duty trucks equipped with automatic transmissions may comment that the vehicle exhibits a clunk noise when shifting between Park and Drive, Park and Reverse, or Drive and Reverse. Similarly, owners of vehicles equipped with automatic or manual transmissions may comment that the vehicle exhibits a clunk noise while driving when the accelerator is quickly depressed and then released.
    Whenever there are two or more gears interacting with one another, there must be a certain amount of clearance between those gears in order for the gears to operate properly. This clearance or freeplay (also known as lash) can translate into a clunk noise whenever the gear is loaded and unloaded quickly, or whenever the direction of rotation is reversed. The more gears you have in a system, the more freeplay the total system will have.
    The clunk noise that owners sometimes hear may be the result of a buildup of freeplay (lash) between the components in the driveline.
    For example, the potential for a driveline clunk would be greater in a 4-wheel drive or all-wheel drive vehicle than a 2-wheel drive vehicle. This is because in addition to the freeplay from the rear axle gears, the universal joints, and the transmission (common to both vehicles), the 4-wheel drive transfer case gears (and their associated clearances) add additional freeplay to the driveline.
    In service, dealers are discouraged from attempting to repair driveline clunk conditions for the following reasons:
    Comments of driveline clunk are almost never the result of one individual component with excessive lash, but rather the result of the added affect of freeplay (or lash) present in all of the driveline components. Because all of the components in the driveline have a certain amount of lash by design, changing driveline components may not result in a satisfactory lash reduction.
    While some owners may find the clunk noise objectionable, this will not adversely affect durability or performance.

    Thanks for all the help. I'll also take a copy of the above to my dealership for service work. I'll make a follow-up post after the work has been completed to let you know if it has helped. Thanks again!

  • marcmarc Posts: 21
    I know there is normal clearance between parts in the drive train but when the clank is loud enough for someone standing 100ft away to hear that's too much slack.

    I test drove a Ford and it doesn't have any clunk or clank when going from I to I, zero!

    That much slop in the drive train = sloppy workmanship and it affect durability. GM is too lazy to fix the problem and they are hoping their clanky trucks will last until the warranty runs out.

    Can't you read?

    "While some owners may find the clunk noise objectionable, this will not adversely affect durability or performance."


    GM ya gotta luv em for all the BS...cause this was my first clunking vehicle, ever!!
  • jed1894jed1894 Posts: 337
    Thanks for info....... sounds like I'm stuck with a clank too. Oh well....... business as usual....

  • Received our 2001 Silverado 2500HD on 1/28 that we
    ordered on 10/13/2000. Have read all the post on
    problems with 2000 models.

    Only have 250 miles on it yet but have found no
    vibrations, wind noise etc. Owners manual now
    says to wait until oil change light comes on
    before changing. It should come on between 3000-10,000. Think I will go with Mobil 1 when it happens.

    Have a A.R.E top ordered and trying to find a
    running board I like. Will order the mud flaps.
    Thanks for all the info you all have provided.

    My first Chewy truck and I am impressed and hope to be able to say that a few miles down the road.
    And don't forget "go bama".

    P. also ordered some polish and stuff from Zaino.
  • obyoneobyone Posts: 8,054
    congrats on the new truck. The HD's appear not to be plagued like the 1500's.

    Be sure to clay before using the Zaino.

    While it may not affect the truck, per post #139 it has affected me. It has aggravated an old back problem & every time the truck does one of it's hard shift & clunks, it sends pain to my lower back. Spend $30,000 for pain, can't enjoy the heated seats now because I am back to wearing my back brace. Can't afford to take the big loss an buy another brand or car. These luxury items and hepa filter is why I switched from my Tahoe.

    Tried to get Chevy to do a buy back or at least help me get into another that won't subject me to pain, but the only thing they offered was extended warranty, so I will have to continue to suffer until they can come up with a fix, [which isn't likely] or I win the lottery which again isn't likely, as my state doesn't even have a lottery. I have been loyal to Chevy since my 69 camaro which was my lst car. Still have 69 rsss convert. & 92 camaro 25th anniversary convt, but thinking of doing a heav ho and buy something that works and not from GM.

    My truck has been in 14 times, maybe l5 or 16 [hard to keep track unless I pull my paper work]

    If there is a new update within the past month please let me know. Dealer has been great at trying everything and anything, its the big tech people and corporate that are ??? Thanks.....
  • I have had a major surging problem since about two months after I bought the truck new in May of 1999. The dealer can't find/solve the problem. CM will not admit it has a problem. I even took them to arbitration with the BB. They decided in my favor. I still have not received any relief from Chevrolet. Any help would be appreciated. I have a stack of paper work that you would not believe. I would like to send it to Chevrolets CO if I knew where to send it. This surge is not a small one. It is a major safety concern.
  • My 2000 2500LT's heater doesn't direct nearly enough hot air into the footwell of the passenger compartment. Around Christmas, while driving from Colorado to Tennessee in 12 degree weather, my wife and I could not get enough heat on the passenger's feet to keep them from being very cold. There weren't any drafts in the footwell, we ended up wrapping our feet in a blanket when setting on that side.

    The dealer checked with GM's Tech. Assistance and were told that the heater was performing to spec., I called that Customer Assistance line and was told that GM has a "Poor Heating Performance Review" currently looking into the problem (so I guess others have complained too.)

    Is anyone else have complaints with the amount of heated air directed at the passenger's feet?

  • obyoneobyone Posts: 8,054
    You stated that BBB ruled in your favor at arbitration. What was the result? Buyback? replacement? This may vary from state to state but GM has 60 days to comply with the arbitrator's ruling. How long has it been?
  • This is my first time posting. My truck is a 2000 Chevy 2500 4x4 5 speed manual with 4:10 locker. It is the extra cab 4 door S/B. The engine has a tick at idle when you first start it cold. The tick goes away as soon as you pick up the idle even the slightest amount. The tick is gone after the engine is warm. Had it to my dealer twice now for this and they tell me "no can fix". I asked them to just bring the idle up a tad but they say that can't be done either. Has anyone else experienced this problem and if so what did you do?

    Sick of Tick!!!
  • obyoneobyone Posts: 8,054
    Your dealer is correct on both counts. There is a temporary fix for it using top engine cleaner to rid of the carbon deposits but like I said it is only temporary. The main cause of the tick at startup is excessive clearance in the rod bearings. I'm sure your dealer knows this as it was resolved for the '01 Silverados. Only way to permanently fix the tick is to replace either the main bearings or the motor. The latter being cheaper I think
  • obyoneobyone Posts: 8,054
    Rod bearings is the correct phrase. Not main bearings.
  • As some of you know I had Chevy buyback a 2000 1500 2wd Xcab LS short bed auto 4.8 355 limited slip Silverado due to highway shake. It also had the harsh feedback through the steering wheel when hitting bumps at speed. I rented a truck last week and they gave me my exact truck, except it was a 2001, no limited slip, and had a 5.3 engine; had a 10/00 build date and the extra frame bracing. I was hoping Chevy had improved, but this one, with only 7 K miles, was horrible. I can say the steering felt better over bumps, and the engine was a slight bit more powerfull, but overall I'd rate it very poor. It vibrated all the time over 65mph, the shocks and springs were so weak they felt like it had 100K on it, the seats were spongy, not firm, the radio wasn't nearly as clear, or powerfull as mine, and it didn't drive well at all. The thing just felt loose all over. The good points are that the 5.3 had a little more power, judging by the seat of the pants feel, although I mainly felt it from 70-95mph accelerating hard. The 4.8 is a fine strong motor and even though I tow 3-4K lb boats, I would not spend the extra money for the 5.3 as it didn't feel much stronger. on the highway I got an avg of 19.4 mpg with the 4.8, and I got 17.7 with the 5.3. I still like the Chevy engines, but after this rental I'm positive I'm going to a Ford for the replacement for my buyback Chevy.
  • obyoneobyone Posts: 8,054
    just curious. How many miles did the truck have? Also, ever consider a Tundra?
