WOW so much info! I don't see the slippage that you speak of, but I am kind of retarded. Do I just take the u bolts off, move the bumpstop out of the way, and put in a new bolt? Where can I get a new bolt? Toyota? Should I replace the u bolts while I have them off, like I did when I did my rear axle swap? I don't really notice a difference when turning.
