My stock 10 bolt rear locked up on me the other day, so I was able to get ahold of a set of 3/4ton axles for practicly nothing. They have been sitting in a field forever so I am going to go thru 'em carefully. I haven't unloaded them yet but I know some items are going to be a must like calipers, rotors, shoes and drums. I plan to repack the front bearings and inspect the diff oil. What about the 14 bolt? What else should I be looking to replace?
