I was playing around under the Jeep this weekend and noticed that I have considerable play in my front pinion yoke and driveshaft. Or im assuming its the yoke, its where it goes into the front diff. Its moves around some. The front ujoint seems fine.
I would imagine it would have some give to it, but not as much give as it has currently. The front pinion yoke is just bolted down right? Is there anything else I need to do to remove it or tighten it. Could it just get wobbled out over time or something. The Jeep is a 99.
I was hoping I dont have to take whole d30 apart. I would say that it moves probably around an inch or so when moving it by hand side to side.
What could be wrong here? I doubt a loosened bolt would cause that.
Any help is always appreciated.

Thanks
Greg

Slight rotation of the yoke is normal. Movement in and out is not.

Its actually like movement to the left and right I would say. Possibly in and out. I totally forget.

I will check tonight. Thanks for the reply.
