drive shaft vibration???

[johnceggleston]

my rear diff pinion seal is leaking and i was going to replace it. but when i got to the pinion nut, i couldn't break it lose. not enough room under the car to swing the breaker bar. so i put it back together and decided to take it to the shop to be fixed.

 

well, after i got it back togehter, i now have a slight vibration in drive line (feels like the rear) when i take off from a stop. start rolling, slight vibration (half second) then it smooths out and runs fine. 97 obw 115k miles.

 

my first guess was the support bearing, maybe it's not tight, but i have no experience with anything like this so i don't know. any thoughts? i guess i should try the FWD fuse to see if that makes a differeence.

 

thanks , john

One of the U-Joints on the shaft might be shot - that could cause the vibration.

Its a u joint in the center of the car most likely. Het under there and shake the driveshaft, there shold be no play in the u joints or bearing. It will get worse with time and make the car undriveable. Go to a junk yard OR a driveshaft shop and let them rebuild it. Dont go to subaru as its not worth the 400.00 + procetag.
