I just put a new front brake hub/rotor assembly on my 85 Chevy Caprice. It's disk brakes in front. The inner bearing and grease seal stayed on the spindle when I removed the old hub/rotor. I tried to get the inner bearing and grease seal to stay on the new hub but the grease seal doesn't fit snugly into the hub/rotor. So, the grease seal was not tight in the old hub, and also is not tight in the new hub. Does it have to be tight? What if it falls backwards a little bit? Is there something preventing it from falling back, when the whole assembly is put back together? I put it all back together (the new hub/rotor and the old grease seal), and it spins well without much noise. Could the seal be tightening up anyway, by pressing against whatever it butts against?
Do I need to take it all apart again, and find a grease cap that fits tightly into the new hub/rotor?
Thanks
