Front Bearing Seal
For the first time ever (not just on a corvette) I've just packed one set of new front bearings and races and installed them in the hub. When I installed the seal flush with the hub, the inner edges of the seal was not in contact with the bearing (there was a gap all the way around). Before I do the other side, I'd like to know if that is normal or did I not get the proper sealsl?
Thanks,
paul

The seal “seals” in two places - first, the metal portion against the mating surface of the hub and the rubber portion on the spindle shaft. The seal is not intended to come in contact with the bearing itself.

Thanks for that info Cal & L88. I think I understand it now and get the picture of how it works. I was only considering the smaller diameter portion of the spindle post, not the innermost portion where it flares out significantly and I guess that's where the rubber seal does it's job. I'll do the other side tomorrow...

Sounds like you got it Paul. And remember, snug up, then back off 1/4 turn. then cotter pin.

I used the chassis service manual method which said to torque the nut to 12 lbs-ft, then back it off 1 to 1.5 flats to align the cotter pin hole.
Unfortunately I did't have a 1-1/4" socket to use with a torque wrench, so I used a 9" adjustable wrench and applied 16 lbs of pressure using a digital scale.
Seemed to work OK...

Paul, 12 ft lbs is F all with that size nut. Basically, Snug.
6 flats to a turn. 1.5 flats= 1/4 turn.
To loose and you will have rotor runout. To tight and you'll burn out your bearings.
