I got some 8 lug 3/4 ton chevy outers from a guy a while back. Finally the time has come to put them on. got one side all together and it works great, but i started on the passenger side and noticed several differences. for one, the wheel seal that goes behind the inner wheel bearing doesnt fit tight, just falls out. another is that the inner and outer wheel bearings sit closer to each other so i can tighten the spindle nut all the way and the bearings still have consideralbe slack in them. Another difference is the rotor on the odd one sits 1/2" in closer to the knuckle, making it impossible to install the brake caliper/pads.the only visual differences between the 2 i can tell, is the "odd" one has longer lug studs, and unlike the other rotor, it has no square holes cut in the piece of rotor between the actual rotor and the hub. what hub/rotor assembly do i have and why isnt it working?
