having trouble with vibration My friends z28 has been vibrating pretty bad. Its worst point is at 60-65 m.p.h. It pretty much does it all the time,even when its in park,you can feel it really bad towards the center console. please help with this problem he needs it fixed pretty bad
mine was the bad steel DS replaced it with an alum ls1 DS now i have a vibration again thought it was the HB but i know its the PP again, i dont know how it went out of balance but it went away when i got my new clutch an PP in and now its back after 15k i thought they didnt have any weights on them
Is it making any noises to go along with the vibrations. The fact that it does it in park rules out quite a few things. I would start by checking the balancer and pully on the front just because they will be the easiest to see. The next thing would be to pull the dust cover off and check for a broke or loose flex plate or loose torque converter. If that all looks good, you can unbolt the converter and push it back far enough to crank the engine. If it stops vibrating with the tc unbolted, it's probably time to pull the tranny.
Vibration in park eliminates the driveshaft, rearend, or out of balance tire being the problem. Start with the harmonic balancer, then maybe check the motor mounts, then if nothing check tranny and converter as stated above^...

doesnt really make any noise just vibrates, feels the worst towards the console so a good chance it could be the converter or flexplate i guess,vibrates a little at idle in park and the more you rev it the worse it does it. sorry the info isnt the best, like i said its a friends car.
