Default Advice needed - recurring rear axle oil seal leak

Just had my 86 cj7 (dana 44 rear) into my local jeep mechanic to
replace my oil seal, bearing, retainer etc, and brake pad on the rear
axle, driver's side. When I picked it up he mentioned that he had
noticed a lot of play when he reinstalled the new axle - he guessed
that a PO had spun a bearing. Basically the bearing was not fitting
tightly into the surrounding housing. He said it seemed ok, but if
there were any problems he may have to spot peen? (weld?) the bearing
to keep it from turning.

As it turns out, it has started leaking again just a few weeks later
and I don't understand whether or not these two issues are or could be
related. He checked the axle for straightness at the time which wasn't
a problem. Anyone have any thoughts or experience with this? I will
take it back in, but wanted to have some ideas ahead of time...

Default Advice needed - recurring rear axle oil seal leak

Ouch, the worst nightmare is a spun out bearing! That 'can' mean you
end up needing a new housing or it easily can mean a used one is cheaper
than the fixes it might need.

Peening means hitting the bearing with a ball peen hammer to make
dimples in it. The idea is these dimples will make the bearing appear
larger by being bumpy so it might hold in the axle tube. I 'think'
there might be a loctite product to help make this band aid hold.

If the peening doesn't work, they can take it apart and maybe machine
the inside of the tube larger so they can fit a shim sleeve in there to
try and hold the bearing in place.

I spun a front bearing on my CJ7 and tried the peening, it didn't hold,
then just went and got a new spindle.

Thanks for the reply, Mike.

(although it doesn't sound good)

By the way, why did you get a new spindle? What does that have to do
with the fit of the bearing in the housing?

Default Advice needed - recurring rear axle oil seal leak

The 'front' wheel bearing in a CJ7 rides on a spindle like the rear one
rides on the axle. If you spin either bearing on the 'inside' it burn
the axle or spindle out. If the outside spins, then you need a new hub
(or tube). I have had that happen too, the hub.

In your case it is the rear and the outside that sounds spun so worst
case is you need a whole new or used rear end or at least the tube on
one side.

'Sometimes' peening can work....

Sometimes a used rear end is 'way' cheaper than fixing what you have....

Lock Tite Sleeve Locker, a weld bead in the housing or beer can shims. Like
Mike says, you may wind up getting a new axle housing.

Good luck.

Default Advice needed - recurring rear axle oil seal leak

Hi Dean,
I wouldn't worry about a loose bearing race. And I don't like his
idea of spot welding it in, it would be impossible to center it!
I'm thinking the seal is his fault, like he laid the full weight of
the axle on it as he slid it in. Or maybe the new seal was twenty years
old and cracking.

Bill -

Thanks for replying. Are you saying that the two issues need not be
related and unless I burn out the new bearing, there is no real problem
with it being slightly loose in the housing as it relates to the oil
seal's ability to do its job?

Thank

I am missing something there too.....

'Every' time a bearing has been spun out on me, the parts need
replacing. If I just put a new one in loose, I don't get 6 months out
of it.

If it is spun enough to cause seal failure, well......
