Like most OE parts, no zurks on the U-joints. Looks like that one got hot, maybe out of round. New U-joint cups wouldn't fit. That would be why it has to be replaced.
Last one I has, I used a torch to burn the plastic out of it. Then used a vise and a socket to press the new ones in.

It was to late for help when you posted. May have to wait for monday morning.

If Pull-A-Part on Farrisview is open today, they may have a good one.
