U-Joint Cap Retainer?
Permalink  
I pulled out yesterday and noticed a few odd noises under my XJ, a few seconds later they got a lot worse & I pulled right over. I looked under the Jeep & my rear driveshaft had fallen off & was banging around.

It was still in the t-case & the rear u-joint looked whole. The clamps were still whole & attached to the rear yoke(?). The caps were gone off of the u-joint, so I looked closer at where the clamps are to hold the caps. One one side there is a little "nub" that looks like it holds the cap in from the outside, on the other side this little piece is missing.

I am assuming that this allowed the cap to come off & the U-joint to come loose enough to come out of the other cap & slide out of the clamps.

So, is this simple to fix?
Can I just buy a little "nub" for this?
Or what do you think?

Your talking about the little "nubs" on each side of the yoke correct? If one is broke than you're going to need a whole new yoke.

This is the little piece that fell off circled.
It did not appear to be welded in place.

Could I just take one off a donor axle and weld it on mine?

That little tab is part of the yoke. Keeps the u-joint from walking in there. I have seen those break before, you can either weld a tab in its place of actually put the u-joint in and put a small tack weld  on the cap where it meets the yoke.. Done that on a few oval track cars in the past.

Jason,

That part is cast, and that little "nub" is part of the yoke. It's all 1 peice. Personally I'd replace the entire peice, not weld it (or similar), especially since you wheel it....

Just my penny and a half worth...

i'd replace the yoke personally since i have many spares.  if you don't have spares i'd put the u joint in there (a greasable one) and tack the cap to the yoke and then regrease it since when u tack it it burns up some of the grease.  we do this on axle u-joints all the time cause we wheel stupidly hard and blow u-joint caps off about everytime we go out.  i'm guessing you probably need a new u-joint in there too cause the cap probably fell off when it broke.
