So I crawled under my truck to grease her up and I found this.

Is there supposed to be this much play?

And I'm assuming a seal has given up...

Universal joint is no good but the little play in the pinion shaft is ok. Looks like you need a new uni joint and a pinion seal.

 

Well crap. Anyone have a good write up (with pics) about replacing U joints?

 

It's all in the FSM. Should be a standard part of your Yota tool box~

 

Well, maybe not all tool boxes, unless you're speaking of the FSM being in the box.

Some of the u-joints are pressed in to the yokes, some are circlip.
The OP's look like the pressed ones. A shop should charge like 15-25 to press them in/out.


As for the fluid leak, the seal is gone. With the worn u-joint, I'd guess the pinion bearings have taken a beating too... though hopefully it's just the preload on the bearings has relaxed a little bit and let the shaft slap the seal into leak mode.

 

Alright well I'll have to find time to tear it apart.. And I gotta find a place that'll do that ^^
