I'm having a bit of a problem with my rear hubs, or it could be the wheel bearings aswell. When I install the bearing they seat just nicely and spin nice and freely when fingertight in place. But when I get out the torque wrench and start tightening them they get stuck and barely moves at all. Do you have any ideas of what might be wrong? The car in question is from 1981 and the bearings are brand new but the hubs are original (I think, at least I haven't replaced them). I have checked multiple times that the bearing seats are all the way in and there's no other visible flaws in the hubs what I can tell, but it seems like the bearings aren't quite touching each other and therefore get stuck when tightened down, no clue why that would happen though.
Any ideas/advice is greatly appreciated!
