The rear end of a Jeep turns both of the vehicle's rear wheels. This rear end -- also called an axle -- has gears and axle shafts inside, and if they get damaged, then you have to remove the rear end. Once that's done, you can either repair what you have, or replace it entirely with a new model. This should take about an hour to do correctly.
Put the wheel chocks around the front wheels. Loosen the rear wheel lugs with the tire iron. Pick up the rear of the Jeep with the jack, using the rear axle as the jacking point. Put a pair of jack stands beneath the axle and the frame, then lower the jack slightly. Remove the rear wheels and tires with the tire iron.
Remove the parking brake cables from the back side of the brake drums with the 1/2-inch ratchet and socket. Remove the brake line leading to the rear end with the line wrench. Unbolt the drive shaft from the rear end with an open-end wrench.
Unbolt the sway bar end links from the rear end with the open-end wrench. Unbolt the lower shock absorber mounts from the rear end with the 1/2-inch ratchet and socket.
Unbolt the suspension links from the rear end with the 1/2-inch ratchet and socket. Lift up the rear end with the jack, then remove the jack stands underneath the jack stands. Lower the jack and then pull the rear end out from underneath the Jeep.
