I just picked up this truck last weekend, and I am going through it, making sure it is ready to go.

Tonight I noticed the rear u-joint is beyond shot. Obviously I need to replace it, but do you think I need to replace the yolks as well? They are gouged up from all the slop, I've never done a u-joint before, so I'm not sure if this a critical thing or not.

Gotta disassemble the joint from the yoke.
If the joint crosses have'nt worn thru the cups into the yoke where the cups press in, the yoke can probably still be used.

 

The real issue is going to be balance if the yokes are damaged enough to throw the balance off you will get real good a changing u joints.

This is only some thing one can tell up close and in person.

From the looks of the pictures you have your work cut out for you.

 

Thanks for the advise guys, I think I will rebuild this one and keep it as a trail spare.
Then pick up a new one, maybe I'll go the tom wood route.
