oh, I also put a bit of fuel tubing (small O ring also works) in the inside of the diff output cup. this helps especially on the front, because when turning the dog bone can come very close to being out of the stub axle's cup. the o ring or fuel tubing bit will keep the dogbone on the edge of the diff output cup...still allowing it to move in some when needed (as suspension moves) but not letting it go to far in and then out of the stub axle's cup. Ive had a dogbone bind or even pop out when turning and hitting a jump. after this mod, that is far less likely to happen.
