What's up guys ok quick story my jeep is at 5" I just did a AA sye with front ds in the the rear and 4* shims all exited to be vibe less I took her for a spin and still had vibes! So I checked my angles I was 2* over no bueno ok no big deal ditch the 4* shims and be 2* under ..perfect still vibes... so I took my front shaft out and vibes completely dissapeared sooooo smooth ! I inspected the shaft no damage u joints BUT the slip in the shaft is seized and you can tell it has not moved in awhile I pounded on it put full body weight on it wd40 won't budge. My question is the slip being stuck a cause for drive line vibrations??? If you think yes or no give me your reason I'm trying to put it in my head ...I'm thinking when the suspension travels up and down it presses into the yokes because there's no slip and by it pressing into the yokes it causes vibes idk thanks for the help in advance!

yea, that definitely the issue.

Yeah. It has to have the ability to move somewhere in the driveline

And with a seized slip yoke, you run the risk of breaking your tcase housing when the front suspension cycles! Seen it before, not pretty!
