My frontend has felt a bit shaky lately so i decided to check on the wheel bearings.
The drivers side felt tight but the passenger side had a bit of play and "The Clunkâ˘" when i wiggled the wheel with my hands. After removing the wheel and the dust cap, i first checked if i could rotate the clamp with a large flat screwdriver. Nope, good. Then i went to check the washer behind the clamp as you're supposed to just barely move it with a screwdriver. Nope, rock solid. Hmmmm. So i loosen the clamp nut and sure enough, i can move the clamp a good 1/3 rotation tighter with my screwdriver. I check the washer again, rock solid. Hmmmm. I tighten it all up, put the wheel back on and no more clunk or play. The wheel still rotates freely. Yet, i was under the impression that you should always be able to move that washer behind the clamp. But if i loosen the clamp enough to just barely be able to move the washer, my wheel feels lose and wiggles and clunks. So how tight is too tight for those bearings?

Andy, your races are most likely not pressed in right. What happens VERY frequently is people drive the old races out with a punch and in the process whack the seating area. Even though it looks fine the seating lip has a slight swell in it and when the new races are installed they don't seat quite parallel. To get rid of the play, you have to over-torque the nut. I can almost guarantee this is what is going on. If you did a search, you will find a thread where I MIG weld the races to shrink them and they fall out. I never ever beat them out.
Most likely someone in the past did the damage and it's hard to see. If the races are perfectly parallel the wheel bearing play will come out the second the nut touches the washer. If you have to force the nut tight to get rid of the play, the races are not parallel. |
