U joints

[amachinistizme]

Just had all my u joints replaced. CV to trans case too.
I'm getting a vibration that wasn't there before at speeds over 40 mph. Any help on this would be appreciated. Thanks in advance.

The drive shaft might now be out of balance. The drive shaft
can be rotated @ the diff 180 degrees and it might help.

I always paint the front yoke to shaft as well as the shaft to diff
to help stop that come-back.
