    I have a 1997 S-10 4x4. I had a vibration in it when it was new. The dealer rebalanced the tires twice, said it was "OK". The owner,(me) said "No way".

    Because I have very little patience, and some mechanical aptitude, I removed the rear driveshaft, and took it to the local d'shaft shop for a balance check. They called me a couple of hours later, and said it was too badly warped to just balance out the vibration.

    When I went back to pick up the shaft, the shop foreman pointed to the sticker on the shaft, and said there's your problem. The sticker said "Made at Three Rivers Plant". He told me that they were getting in quite a few shafts from there that just weren't assembled "square". They made a new shaft for me, I installed it, and the truck was smooth as silk.

    Took the original shaft back to the dealer, and after a few minutes of "discussion" and a ride around the block, they agreed that the shaft was indeed the problem and had GM reimburse me for the repair. They said that if they ordered another shaft through GM parts network, it would also be made at the three rivers plant, so it could be bad also. Just somthing for you guys to ponder....

    It might come down to that!!! Hopefully NOT, They might void the warranty or something?

    this repair wouldn't void a warranty, as the driveshaft is actually a warrantied item. In other words, the dealer(so to speak) took out the bad part and put in a good part. I say "so to speak", because that's where the "discussion" that I originally spoke of, came in to play. Good luck with your truck.

    Read post #2 from 2 months ago.

    Yep I had told the dealer about this 1 month ago, but the said Nah! After them having a vehicle for over a week, and calling Chevy, they looked at everything!

    Glad to hear you finally got it resolved. I'm surprised they didn't look at the most likely causes from the start.
  • I have a 2002 Trailblazer that is throwing road debris from the front tires onto the flanged area in front of the rear tires. I have 13000 miles on it. It has never been off road. In conversations with Chevrolet they will not do anything to make it right. I asked for mudflaps and repaint of the area. Since then I have discovered two more Trailblazers with the same damage. Since the 2003 and 2002's are the same body design it will be a problem with both. Everyone should check their vehicle immediately and if you find damage file a complaint. I will be contacting the attorney general and the BBB. I, also plan to provide this information to dealers so that they will be under pressure to get this design problem taken care of.

    around gets rock chips in front of the rear wheels. That's just the way it is.

    Debris gets kicked up by the front tires and the air flowing around the car, in a circular motion, brings some of it into the vehicle's body.

    Save the calls to the Pentagon and focus your energy on something much more important. This is certainly NOT a Trailblazer problem.
  • Thanks for your response. I know that all vehicles suffer this type of damage, but you haven't seen mine. It is pretty bad and after so few miles. Take care.

    I own a 02 TB that has this vibration at 67 - 74 mph. They changed the springs which made it worse. I opened a case with GM and BBB today. Lets keep the pressure on GM to FIX these vehicles. Anyone with news from GM let us know. If you are thinking of buying a TB you had better wait. This is a major problem that GM seems to want to ignore.
