1996 Ford Thunderbird Vibration - Drive Train & Driveline
Question: The back seal in the transmission was leaking and when the shop repaired it they didn't connect the universal properly and it flew appart at 100k. It damaged the drive shaft and a new one was made up, balanced and installed. The shaft balance was re-checked but it still vibrates at about 70k. and up.

Technican: Hi;
Most likely the rear shaft output bushing is shot. The only way to replace the busing is to take the tail shaft housing off. This is minor repair. The only other thing that comes to mind is that the splines got messed up. But this is very unlikely. . Owner: Thanks for your reply. Trans. Shop contends rear bushing O.K. No leaks etc. Can bushing be shot without leaking? Any other suggestions? Thanks
Jim Technican: Hi:
The bushing can be shot without the trans leaking. Also might want to have the driveshaft rebalanced. Have the shop take the drive shaft loose and rotate it 180. degrees and see if this changes the vibration. Thanks. Here's How To Get Guaranteed Solutions In Minutes
