Drive Train Vibration.

[samwise68]

Hey all,

Over last weekend we replaced the clutch in my GMC. well, the new clutch is great.

however, there is some vibration coming from the drive train. driveshaft, carrier bearing, u-joint, maybe even loose bellhousing or tranny bolts, idk.

of course we had to take the driveshaft out, and i lost one of the needle bearings in the bearing cap for the rear u-joint that bolts to the rearend. could this cause some fairly mild vibes?

or does the carrier bearing have to be lined up or adjusted in a certain way, to have good harmonics?

anyone willing to chime in, i would appreciate it greatly, just to have some ideas before i go back under it this weekend in attempt to smooth 'er out on the road.

thanks in advance all!
