On saturday I changed my differential fluid, and the cover really needed repainted, so I did that, and decided to just paint the whole axle and such. I sanded the axle a little with an attachment for my cordless drill, which is hard to do because of all of the nooks and stuff on the axle, then rubbed everything that I wanted to paint with acetone. I sprayed it with some rust stopper paint from ACE Hardware, it worked pretty well.
I like to make my truck look different than everyones so I painted the axle gray, I know some aftermarket axles are gray so it looks aftermarket in a sense, haha.
While I was painting, I just sprayed random things black to stop some rust and look better. You can also see my crazy leaf packs.
