So I picked up some used axle shafts for my TJ just to make changing the u joints a little easier because i don't know how bad mine are going to be and I'd rather have these prepped and ready to throw in. They do have a little bit of surface rust on the races with 1 minor pit. I was wondering what the best way to go about taking that off would be. I was thinking maybe metal polish? I'm too scared to sand them.
just scuff it up a bit with some 400... i've done it several times with 12 bolts, 9" and my rubicon's rear 44... it's just simply a spot that rides inside the inner race so scuffing it up won't hurt anything... just dont use an angle grinder... lol
find a local blaster and have it soda blasted. it will clean off the rust but wont pit the metal under it. have the whole thing done and then paint/powder coat anything that will be exposed to the elements.
