GMC Sierra: Problems & Solutions



  • obyoneobyone Posts: 8,054
    glad it worked.


    My truck's VIN didn't qualify either. However, District rep made exception and told dealer to go ahead and do the TSB anyway cause the only other option was to pursue buyback as I wasn't about to drive the truck with no vibration.

    I have a 2000 5.3 liter 4WD automatic Sierra with less than 5000 miles. Six times the past three months - after the engine is warm - the engine will not start. If I wait approx. 12 minutes before I attempt to re start the engine, it starts right up. The service engine light does not come on (no fault codes are stored in the computer). Another problem, that may or not be related, the "Security Light" does no go off occasionally after starting the vehicle. I appreciate any suggestions. Thanks, Gene1225

    I have a 2000 GMC 1500 5.3L that I really love. However, I have had a sound eminating from the front end like something is loose. I have taken it to a good friend that is a mechanic. He also owns the Goodyear dealership in our town. He cannot find anything but verifies that what I am hearing is not normal. He is also an avid GM fanatic. I shopped this truck around before buying. I must have driven about 20 different trucks at 5 different dealerships. Several had the "bounce" in the front ends at 65 - 70 and the shimmy at those speeds. I just kept test driving and talking to salesmen, who did not know anything about shimmy problems until I found this truck. It has less than 9000 miles on it and I am leary about taking it in. It seems that when the Dealerships start working on the front ends, they continue to have to work on the front ends. I don't remember, nor can I find anything about this particular problem. It sounds like the shock is loose, but I can't find anything. Has anyone else experienced this?
  • obyoneobyone Posts: 8,054
    need a the facts. Sounds like something loose in the front end is of no help. If you give the details of your problem. i.e. when it happens and under what conditions...others who are not associated with Goodyear may be able to help you.

    Good luck.

    It happens all of the time and at all speeds. When I say that it sounds like something is loose in the front end that is the best I can equate the noise. When I go over bumps it sounds like something (like a shock) is "swinging" loose at one end and hitting a stop, much like a pendulum. I have had great luck with this truck up to this point. I had read about the vibration problems with the Silverados and Sierras and found that same problems with most of the trucks I test drove. I found this truck and it didn't have the vibration and hasn't had any problems with the tires to this point even though they are the Generals. However, this problem is only around with I go over bumps. If I yank the wheel one way or the other at low speeds (5 - 10 mph) it will occasionally do it also. I know it sounds weird, and I use to work on my own cars, but that is what it sounds like. I have had it in the shop once because a ball joint went out and my buddy thinks that they may not have put the spring back in the proper position. It was at 6,000 miles. I have had this almost a year and, as you can tell, I don't drive it much since I have a company vehicle that I drive to and from work. Any thoughts?

    that needs replacing. It is very common on the '99 and '00 and it doesn't matter whether it's a 4wd or 2wd. Inspection of the steering shaft will reveal nothing as it will look normal. The sound it best described as a clunk, is felt in the steering, and usually happens making turns over semi-rough surfaces. If this describes what's happening, post your reply and I can either email or post the TSB.
  • stogeystogey Posts: 3
    It is not just when making turns over rough surfaces. It is apparent when going over OR turning on rough surfaces. I am at a loss. However, I will be taking it in to the shop in the morning and would like the TSB on the steering shaft as that bears knowing.

    Note: there are drawings that can't be transferred. I don't think the dealer would need them, but if you do, email me with you email address and I'll send it to ya.

    Does anyone know if the vibration problems with the 2001 Silverado 1500 or Sierra still exist.
    I am about to purchase a new truck ( the old 78 Ford is really rusted ) and have some concern about these problems posted on the boards. I really like the GMC drivetrain and interior opposed to the Ford. Like most of you know , a little research goes a long way in avoiding buying inherit design problems in a $20K + vehicle .Thanks
  • obyoneobyone Posts: 8,054
    the vibrations never existed. Other than that, I haven't seen one on a 1500 the 2500HD has seen some.
  • gwallnegwallne Posts: 3
    In reference to post #190 I was concerned about the infamous shakearo problem with the front end at speeds of 35 and 65 mph. I know that extra frame supports were added for the 2001 model year and some changes were made to the steering but GM hasn't put the sliding window
    back as a option . It was removed on the 1500 due to leakage and breakage from undercarriage frame flexing from the new designed frame.thanks

    It sounds like you have a bad tire try rotating your tires around rear to front.
  • txyank1txyank1 Posts: 1,010
    I drove 200 miles on an asphalt highway this past weekend and did not experience the bounce at 70 mph that I do on the concrete that I drive on every day.
  • jlflemmonsjlflemmons Posts: 2,242
    North I35 out of Round Rock, Texas has a stretch that will make you swear you have a tire out of balance. It is a ripple in the concrete that is just the right spacing that will make it feel like a tire is out of balance at 65. Turn around and go south and the vibration disappears.

  • obyoneobyone Posts: 8,054
    that causes the bounce in certain areas on concrete highways....
  • ryanbabryanbab Posts: 7,240
    could that be dried "hot liquid magma?"
  • obyoneobyone Posts: 8,054
    the cooled magma is smoother than the concrete...and it's free.

    I did get some bounce coming back from Seattle on Interstate 90. In fact at about 85 I decided I had better slow down or my guts couldn't stand it much more - kinda like a stiff legged horse in a trot. I was looking at the surface and could see some ripples, probably from trucks. I am not sure if the wheel base is just the right length to amplify this, or whether the shocks are not quite stiff enough, or both. When I get to Calif., I am going to have stiffer front shocks put on.
  • obyoneobyone Posts: 8,054
    the stiffer shocks will get you a stiffer bounce.
  • txyank1txyank1 Posts: 1,010
    Jim, I drive 183 every day between 620 and 290. Will be going up I-35 next weekend. Another thing that's worse on this '01 than my '99 is the harshness when you hit a bump. Even a small one. Both vehicles with the "smoothe ride" suspension. I'm very dissastisfied with that. The "bounce" sometimes is so bad that you're sorry you ate that last burrito! Usually at it's worst on a slight upgrade.

    What are those, Mother Nature's Speed-bumps? Do they end up repaving afterwards? Guess you really need 4WD down there, just to drive the roads...

  • obyoneobyone Posts: 8,054
    ones that leads to a subdivision...or what's left of the subdivision doesn't get repaved.
  • Hi all - new to the community and was wondering if anyone else was having this problem. My 2001 Sierra 1500 4x4 drifts to the right and has been ever since I picked it up from the dealer. I've had it in to the dealer twice now to correct the problem and it is fine for about a day then goes right back to drifting to the right. Anyone else experience this? Any ideas on how to fix the problem for longer than a day?

  • obyoneobyone Posts: 8,054
    right pulling for a day? Have they tried rotating the tires?

    I remember GM changing the powersteering unit to correct the pulling effect in some cases.
  • Obyone - thanks for the reply. All the dealer did to rid the problem for the day was align the front end. They have not tried rotating the tires.

    I'll ask about the power steering unit next time I take it in.

    I,ve got a 2k 1/2 ton sierra 4x4 3door and know of two other owners with same truck only chev with
    same problem. The rear frame is broken approx. 11"
    forward of rear shackle. I towed a four place snowmobile trailor (5000lb) with class 3 hitch it actually bent the frame down at this same weak point. The other trucks were used on a farm over rough roads approx 60% of every day. One of them
    broke completly through on one side. All owners should check their frames. Has anybody else already experienced this problem?
  • tucsonjwttucsonjwt Posts: 283
    I have a smooth ride long bed regular cab Silverado and the velvets did help on the tar strips.
    It could be about a $170 experiment if you want to try it. Also, I have Edelbrock IAS shocks, but I think they mostly improve handling/cornering, and don't improve the ride much. Others, like oby, report improved ride with the Edlebrocks. I think the Edelbrocks go for $225-$300, depending on where you buy them and the Edelbrock rebate.

    I have a 2001 SEE 2500HD, very satisfied with truck except for a slight surge at low speed-light throttle. Any one else have this experience and what was done, I have not gone back to the dealer yet.
  • mugstermugster Posts: 16
    This is for Stogey about post number 184. My 1999 Sierra is in the shop right now for the same type of noise. I described it as a loose shock. I already had the intermediate steering shaft replaced.

    I did a ride with the mechanic and it is his opinion that it is coming from the rear of the truck and that the noise is transferring through the frame to the front end. I thought it was in the front end also. But it banged only when the rear end hit the bump. Not the front. If he finds the problem, I'll do a post
  • txyank1txyank1 Posts: 1,010
    thanks for the info.
