Badly worn u joint
I developed some driveline noises that were easily tracked to a bad u joint at the front of the rear drive axle. The attached picture is what I found. The cracked leg was the obvious fault when still assembled but after pulling it, I found two legs bdly worn out of round.
I have not seen this before and want to ask if this may a symptom of something failing. Speicer 1310 greaseless are replacing both u joints in the driveshaft.
