what a journey...as some of you know my situation, Im going to a new thread concerning how to find the correct parts. I had issues with this truck as described in the threads, "is ACDelco 10-4051 gear oil discontinued", and "Thump thump G80 and confusing gear oil"....so I decided to replace the cross pin shaft and C-clips before I put diff cover back on "again". I inspected the outer axle bearings very close, they seem very new and seals not leaking. A concern was just a smidge of side play, which some say is normal with cylindrical roller bearings (not sealed bearings). I ordered a cross pin from auto zone and although it was supposed to fit, it was entirely different. I order another from rock auto, which is pictured. All the info about the part is "it is a fit"...does the extra length matter? or did I get the wrong part? Ordered C-clips off amazon which were coming from yukon gear, I got one, charged for two, but no more available. Geez, this is nuts. (the shorter pin is original, the longer is from rock auto)
