Ive used everything from cotton balls to hot glue. Dont waste your time trying to lock a planetary diff with fluid. Cottonballs are the best Ive used so far. if youre running a call with a ball diff, you can lock that a little easier. take out the balls and make an e-tape washer around the gear and tighten the screw on the inside of the diff shaft all the down and it should lock.
