Weird Vibration at deceleration

**Loudz28** · 12-30-2007, 10:36 AM

ive been trying to diagnose this vibration ive had since my clutch install. it happens the most when decelerating from 60+mph. feels like its coming from right under the shifter, but the shifter isnt shaking that bad. i also put in a poly trans mount, but its been about 1500miles, so i woulda thought it was broken in...any ideas?

have you had your tire balanced lately?

Already took out the driveshaft? Shouldn't be that hard to take it out again and get it balanced lol. Did you make sure you put your driveshaft in the exact same way as you took it out (when you did the clutch) because that could cause vibration (due to it getting torqued on for all those miles before you took it out) and when you replace it a different way, it will be out of balance. Did it in a truck of mine when I did the clutch. The fucker fell out on the road and shattered the back of the shaft.

If you did something when you installed the clutch, i.e: put stress on the new clutch disk/ plate when sliding in the tranny, that could cause a problem as well, but I think that would result in slippage more so than vibration.

hmmm i had aamco due the clutch, i kno i kno bad choice. ive heard it before and im on my 2nd clutch with them. im starting to think that they just fucked up in the installation. again.

are your wheels strait? one or more may be warped. i had that happen to mine, and it did the exact same thing.

however, poly trans mounts, especially when you have some good LCA's, tend to make everything vibrate like hell.
