Moses thanks for the reply I was working on some other projects the last few days and just had time to pull this thing apart and get back with you. When I posted the other day I had only taken apart and reassemble the drivers side. I replaced the axle seal installed the axle and bearing cup and set 0.006" of endplay and installed all parts in the order that are shown in the above diagram. Today I disassembled both sides and found that the drivers side cup in backing out and that is how I am loosing endplay. I could remove the shim but that would only make my endplay go from 0.090 to 0.085" after the bearing cup walk to the end of the axle flange. when i had 0.006" end play my driver side bearing cup was seated into the axle flange about 0.090" deep. so this is why i asked if they make shims that go behind the bearing cup and #6 on your diagram. i also after tearing all the way down today wanted to verify someone didn't swap axles on me my drivers side axle is 28.5" and passenger side is 31.5"

Hi Moses, I have your book and I am working on a AMC 20 axle that was leaking at the driver axle seal. I installed axle seal, axle and drove the cup in flush with the axle flange. At this point I checked axle endplay and have 0.006". I then installed the shim that was on the vehicle, backing plate, etc and torqued the backing plate to 38 ft lbs. I rechecked endplay and had 0.006". moved on to install hub and after torqueing to a minimum of 250ft lbs and getting my 1 and 5/16" both axle have 0.090" of endplay. Do I need to replace the outside shim or is there a shim kit that goes between the bearing cup and backing plate. Both axle seals where previously replaced two times by two different people and I am beginning to believe end play has been the cause all along. Thanks, Brian
