Re: Advice needed - recurring rear axle oil seal leak
Not to beat a dead horse here guys, but would a loose bearing race
actually cause a brand new seal to fail within a couple of weeks? Or am
I likely dealing with two problems:
1) dealing with the spun bearing
2) a poorly done seal/bearing job

Re: Advice needed - recurring rear axle oil seal leak
YUP! That's what I'm saying, I've driven over two hundred thousand
of three on my Bronco front hub with a worn in seat, I just knurl the
seat a little with a center punch each of over ten times I've repacked
them since. Your seal is between the bearing and the differential:

Bill, you need glasses! That seal is outboard of the bearing, same as
mine! The bearing must be pressed off first, then the seal

Re: Advice needed - recurring rear axle oil seal leak
It is simple to check what's up. Just jack up the corner and grab the
back wheel to see how much play is in it. If you can feel up and down
or side to side play, then the bearing is the cause. Then look at the
axle tube just behind the brake plate to see if it has a heat mark on
it. If it does, the bearing is at fault. Either or in those cases.
If however there is no lateral play or obvious overheating, the job is
suspect, not the seal in my opinion.

Re: Advice needed - recurring rear axle oil seal leak
It is simple to check what's up. Just jack up the corner and grab the
back wheel to see how much play is in it. If you can feel up and down
or side to side play, then the bearing is the cause. Then look at the
axle tube just behind the brake plate to see if it has a heat mark on
it. If it does, the bearing is at fault. Either or in those cases.
If however there is no lateral play or obvious overheating, the job is
suspect, not the seal in my opinion.
