Re: 2002 Trailblazer Lt with vibration/shudder problem
I am having a simular problem and mechanics say they don't hear/feel anything. My problem is when I excellerate it revs way louder than it's suppose to and when I am stopped, foot on brake, not in park, it vibrates and is still louder than it's suppose to be. When I get the reports back from mechanics, they've entered what I've said the problem is wrong. The latest solution given by 2 mechanics, one being a Chevy dealer, is motor mounts (supports) needs to be replaced, a $500 job. They say it's causing the vibrations and possibly the vibrations are causing the loud noise down through to the back of the car. A third place said he doesn't see a problem with them and wouldn't change the mounts unless they were broken. But does see a small hole developing in the muffler, something he didn't see the first time I brought the car to him. I'm at a loss and feel I can't trust any of them.
