Well i did have good luck with the rear welded spider gears for about 6 months then i don't really know what went wrong but my whole rear was trashed. Ring and pinion carrier yoke bearings but i don't think the gears where ever set up right and i don't think all the bearings where replaced, so i don't know if it was because of installer error, shirtty genuine gears or what. But now 600 dollars later Ive got a brand new 3rd 5.29s and a spool we shall see how it holds up.
