Well I seem to have figure some of this out. I measured the offest between
the bearing cup and cone, new and old are the same, 0.128". Then the offset
of the seal between the metal center and the outer face lip, 0.167". That
leaves an interferance if you will of 0.039". First I took out the seal and
ran the truck 16 miles, the temp of the hub was the same as the front,
around 99degF, ambient temp was 88. The other 3 rear hubs were running
around 140degF. Then I did a little creative reforming of the seal in a
press to reduce the interferance from 0.039 to around 0.023 and reinstalled
it and took it for a run again, same 16 mile run, now the reworked rear hub
runs just under 105degF. The difference of 35 degrees is the difference of
feeling just "warm" to feeling hot enought that you feel compelled to take
your hand off after one second, two tops. The real proof would have been to
have saved the old seals, which normally I do same all old parts, for some
reason I didn't this time. But since I waisted all this time figuring this
out, I think I'll just proceed and finish the other three the same way.
Iola here I come !!!
Speaking of which, if anyone is going to be at Iola, I'll be in W24 and W25
as far as I know.
Thanks for all the replies.
