I realized as I was driving home from a recent car show (first time I've driven the car since September) that I have developed a significant driveline vibration in the camaro. need to figure this out and fix it before this years track days start for me (April/ May). Here is some background:
1991 Z28 LS1 T56 Stock driveshaft Stock Rearend Vibration happens only when on the gas (most noticable cruising at highway speeds). Take foot of the gas and the vibration goes away. All I can think of is that I converted the T56 from a LT1 style to a LS1 style when converting to the LS1 motor. It didn't have this problem right after completing the swap, but I'm sure it's probably developed over time (I don't drive the car much). I can't rule out anything yet, but It's unlikely to be the driveshaft or rearend since those are about the only thing left in the car that are stock and original. Suggestions? |

Alot of times, a vibration upon acceleration but not on decel is related to a seized u-joint.
