I've been looking for a phrase that adequately described setting up gears... :D
Another way to check (if possible since brakes sometime lock up in the junkyard) is to spin one of the axleshafts and count the number of times the yoke spins. If only one axle shaft turns, rotate it around twice. If both axle shafts turn in the same direction and at the same rate, turn the axle shaft once. If they spin in opposite directions, you're going to need to get one to stay still while you turn the other twice.
