Clutch or Flywheel Vibrations

[john67]

Hello to all,
New to forum so my first post may need some help. I own a 2003 Chevy silverado 1500 4.3l truck with a 5 speed manual transmission. Just had clutch pedal to flywheel replaced with all new parts. Still getting vibration at 2000 rpm and above going through the gears,or just sitting on driveway when With clutch pushed in and rev engine to 2000 and above. Any thoughts on what could be wrong or what may have been missed during installation of new parts?

did you check the harmonic damper to see if the rubber is shot and the outer ring has moved?
have you checked motor mounts?
in the driveway, in neutral, without stepping on clutch pedal do you get the vibration?

sad to say but I paid to have all the work done. I have no idea what was checked or not checked. The technician if qualified should have checked the second time the truck was returned for the same problem. And yes, with truck in neutral and stepping on gas pedal still get vibration 2k and above. Now truck is getting worse, after everything heats up after say 1/2 hour of driving vibration is more noticeable then starting from a cold start.

All of this only started after work was performed.Before that the truck was running great given her age and mileage.

has anybody checked the harmonic balancer?
what exactly has the shop done to resolve the problem?

 

[john67]

nothing yet. Would there be a reason why the harmonic balancer would have been affected by the work that was done? All was fine before they performed the work. Last reply from garage was the problem was chevy silverados are know to vibrate when getting close to 100K miles. This information was gathered from an online forum, unknow what forum.

it wouldnt be the first time in history that something is done at a shop and a new symptom develops caused by something totally unrelated to the work that was done. You want to know what causes vibration in a vehicle that is not moving, it is either the damper or the flywheel/clutch assembly and the damper is a hell of alot easier to look at then tearing apart the flywheel/clutch assembly. I assume you have no check engine light on. Good luck.
