Fnt. Wh. Bearing Preload double Spec.

[MH_Stevens]

Having got the hub back on after this front axel service the preload that has spec of 6.4-12.6 lbf is 18 lbf. One factor may be that I noticed after I had installed the oil seal over the inner bearing that I could not turn the inner bearing by hand. My manual does not say about limiting the pressure needed to put in the oil seal. I banged it home tight - was thing wrong of me? What's my problem and what do I need do before I continue to install the lock washer?

Thanks

Did you seat the inner race completely? The bearing should still spin freely.

The inner seal should be installed flush with the end of the spindle you installed it into. If you pounded the seal in until it would not go anymore, as in up against the bearing...it's time to buy a new seal and do it over.

Yes, you have seated the seal too deep. The outer face of the seal should be flush with the outer edge/lip of the back of the hub (not spindle). Seals are not reusable, so go get a National or Timken oil seal part # 226285 from your local parts house and tap it in until its just flush.

So I guess in this case it wouldn't matter if you did the preload with a fish scale?

Baaaahhaahaaaa....or a fish or a fishing rod for that matter.

Thanks guys. Wow that fish scale really paid for itself by revealing my mistake.

no need for a new seal. Remove the outer bearing and replace one of the nuts. Now grab the hub and pull it forward bumping the nut against the inner bearing while turning the hub with each successive bump. You don't need a lot of force here and the seal will come out with out any problems.
