Body Vibration

[ScottS]

Thanks Again,

This pinion angle thing is very interesting. When I installed the new drive shaft I tried to measure the angle that was suggested (plus or minus 3 degrees). It was very difficult because I was using jacks at the time to get under the car. But, from my initial measurements I determined the tranny had to be raised about 2 inches to get me in alignment. I fabricated a 2" aluminum spacer that sits on the crossmember and attaches to the trannly mount. That put the angle of the drive shaft more in line (perpendcular) with the pinion. That in turn raised the engine more perpendicluar to the frame.

Now for the interesting part. When I do get up to 60MPH I have a vibration sound coming from the rear drive train (drive shaft back to rear end). When I push in the clutch at 60-70MPH the vibration sound is still there. At lower speeds no drive shaft sound.

So, maybe the two are related??

So, at this point maybe I should go back to the drive shaft shop and get some professional help...

Thanks,
