Gary,
I am running the double bearing rear hubs as well.
When I looked at the double bearing hubs, I found that the seal lip(where it
meets the axle tube and actually does the "sealing") rides on the axle tube a
tad
closer to the radius'd edge of the axle tube than the standard hub does. It is
possible that the seal lip is actually riding on this radius versus on the flat
area of the tube where it should be. Good bye to any sealing action if that is
the case.
My simple solution to this was to have a thin shim made that fits right in
against the stepped shoulder of the axle tube, where the bearing rides, thereby
moving the bearing hub out ever so slightly away from the radius'd edge of the
axle tube. The lip seal then rides on the flat and smooth(hopefully)surface it
was intended to ride on. Of course, by moving the hub out a little, you may not
be able to use the locking tab washer on the big nut holding this all together.
I have used red loctite on that nut, and marked it to see if it ever moves. In
4
years of racing with these hubs, the nut has never backed off or loosened one
iota using this method. I am well aware of the consequences if that nut would
work its way loose and off, so I check it regularily for any movement.
Another alternative to all of this is to use sealed bearings in the hub. I
think
Elmo has tried this.
He may be able to shed some light on that.
