Ok, on the 89 and later 14 bolts that use the single spindle nut, key, and snap ring, is there supposed to be a washer behind the nut like the older 2 nut systems used or no? The diagrams I am looking at had no washer there and the dealerships are saying they do not have a part # for one. But when I pulled my axle apart there was one in there on each side and I put them back on when I rebuilt it. Is this a fluke or is it really supposed to be there? Could this be what caused my bearing to die on the highway?
