The rear body mounts in bolt from the bottom of the frame and come right out without lifting the body. Mine was moving slightly until it broke.Sorry to revive this thread but I've got the front and center drivers out no problem using the torque wrench and heat method. On the rear I've put 90ftibs into it without moving. How hard was it for you to remove the mount after it broke? Did you need to jack the body up?
There was just enough sticking out to get an ez out socket on and with heat directly on it came out easily. Worst parts was waiting a couple days for the Jeep dealer to order the bolts. It was a 2 pack for about $11.
