Default U joints loose in half shaft

91 ZR-1 78000 miles

I have a clunk on the left rear side of the car. The bearing seems loose on that side, so it's getting changed.
I pulled the half shaft, and the u joints slip out with hand pressure. You can feel a slight lip inside the ujoint yoke hole. Can these be repaired?
I realize the joint won't fall out because it has clips, but the extra clearance can't be good.Someone sugested Permatex loose fit bearing adhesive, but this seems like a temporary fix at best.

If your going to change the U joints go back with the "Spicer" brand joints they have proven to hold up extremely will in the C4s.

The problem isn't with the ujoint. It's fine. The problem is with the holes on the halfshaft that hold the ujoint. The've opened up a bit and the ujoints are now a slip fit instead of a press fit. Can this be repaired?

I'd try a to press a new joint in to see if it was just the old U joint cap that got wollered out. I don't know it it would be worth repairing or not.

Well I think your going to need new half shafts and / or yokes...try the C$ parts section. Those things must have been banging around for a long time then?
