Since the HD U-Joints are on backorder, I decided to try fabbing something up to fix my Fazon's center-rear broken joint. So far its holding up to 6s.

I used a dremel to cut a piece out of a HPI Stub axle and used that as the pin and welded it in.

Its almost like the old ones fell out. Maybe they were not pressed in good enough? I don't see how it could sheer those off. The tolerance is pretty good and not much play.

Great solution to get running again. You'll probably never have a problem at that U joint again...

Yeah hope not! But I did get center front/rear HD driveshafts for $50 on eBay, pulled from a Big Rock I suppose. The HD ones have about 30% more beef on them. Will keep you posted on how these go!
