Jeep YJ Pinion yoke play....

Hi Everyone,

I developed a bad drive-line vibration over the last couple of days. Assuming it was a U-joint issue I pulled the rear drive shaft. The u-joint at the pinion was totally shot with all the bearings dissolved in one of the caps. Upon further inspection I noticed that the pinion yoke has a bit of play on the pinion shaft. It seems to be moving around on the flange very loosely. Here's a link to a video of how it's moving around:

I am planning an axle swap soon but the Jeep needs to carry on as my daily driver for about another month or two. If I replace the u-joints and carry on is an explosion inanimate?

Thanks for any help!

Try to tighten the pinion yoke nut and see if that helps.

Mine was loose once and just needed tightening. You may need a new nut also.
If it's not supposed to move and does use duct tape.
If it's supposed to move and doesn't use WD40

Romove the yoke and replace it. New nut and rubber gasket torque to spec and see what happens.
