huh? have you looked at it yet? its easy... lift the jeep up from the rear bumper or body and get all the weight off the springs, unbolt the luge nuts, remove wheels/tires. i usually to mine one side at a time. theres 4 nuts on the ubolts, unbolt them, pull the ubolts out, then theres one bolt on the front of the spring and one in the rear. unbolt them and thats all there is to it. most of the time the axle will shift about an inch, front or rear, whatever it decides to do. so you might need a strap or cumalong to line it back up? if it doesnt shift much and is just barely not lining up then most the time you can just muscle it into place.
