Still don't understand?
Take a look at the instructions from Moser: http://www.moserengineering.com/aitd...aitfile_id/88/
Notice that the EXISTING BRAKE BACKING PLATE FROM YOUR JEEP
must be slipped onto the axle BEFORE the bearings are pressed onto the axle. (As well as the bearing seal.)
Nobody makes that part anymore, and if they did the kit would cost significantly more. Before you go to the shop, take the time to make sure the area immediately around the hole that the axle slides through is flat. You're going to apply some sealant there when assembling the axle and want that area to be flat for a better fit and seal.
Buy a decent set and you'll be farther ahead. Mosers are EXCELLENT!
AND READ THE DIRECTIONS! TWICE!
They are simple and straightforward. If you get lost or don't understand, get back to us. We'll go over it with you. When I do it, I do it in two stages so that I can install an "assembly" with fewer moving parts covered with silicone to manage. It takes longer because the silicone needs to set and dry, but I believe I get better and less messy results. It takes more time to go and have the bearings pressed than to do the job. It really is pretty simple.
