you are supposed to swap in the inner bearing cone from the kit? its not already in there - the correct one? just fitted one of these kits 70-77 gm rotors tp hat spacer and the spacer after the outer bearing ONE side is fine one side feeel completely wrong spindle nut tight - outer bearing jams on spindle really loose bearings still do i look and see if I have odd outer cups left in the kit?
Nothing you can do except take the good side apart and have a good look comparing both sides, the spacer is really nothing but a large washer, sure seems like a shipping error , do you have pics?
yup, it says in the instructions for a kit I installed in the late 80s....Remove the seal, bearing and inner race from the rotor, and install the new bearing and race
