Vibration after rear U joint install.

2002 access cab. Found center carry bearing kind of loose and installed new. Then found the rear U joint was shot. while wrestling the drive shaft the yoke dropped out. Lined the splines up so the yokes all looked good and put back in. Major vibration above 30 MPH. My next try am thinking it must be 180 degrees out of time. Anyone have a better way to approach this?

 

Try moving the splined section 180 out. I found pics of zerk fitting direction online, and lucked out when i didnt mark my driveshaft, but all the balance weights are on the same side.

 

Thanks for the quick answer back. Going out now give it a shot.

 

Quick search, but it might have been this one.

 

Solved some dummy got a retainer clip in wrong groove that let the cap work back out about 1/8 inch.
