Had to change complete assembly on both sides
If you need to change the backing plate or it had rusted out like mine, you will have to remove the axle shaft connect to lug bolts. I had to change both complete assemblies, I hope yours is not a 2006 or 2007 model because the assembly for each side is $250 - my dealer quoted $375 each. After you slide the axle off, you can just rip off old parts as the new assembly comes with everything installed. You remove four nuts and disconnect the abs and cable. Clean everything up, then reinstall the four nuts the abs and the cable, slide the axle shaft back in and reconnect. There is a forum I saw that explains how to this somewhere. Then go back to putting the rotors, pads and calipers back on. I changed the calipers and the rotors and pads also because it was removing one side because it had a bad caliper that I discovered how bad the backing plate was. So now I have new parking brake assemblies new rotors, pads and calipers on the both sides of the rear. You can see by the pictures that I have the axle shaft slide out, since I am doing both sides, makes things easier, I am waiting for new seals to come in the morning because I figure since I have it apart, I might as well do that now, since they are only $20 each and with my luck, after having all of this apart one of them would start leaking in a month or two. I also had a caliper which is what started this project so when done it will be an entire new brake system since I doing both calipers, rotors and pads. I cannot drive because of the medicine I am taking and fighting lung cancer so I am doing all this to pass my 2006 Jeep 4x4 6 cylinder Liberty Renegade on to my only son who is about to turn 23.
