Rear axle seal leak question?

My 2008 JKU rear seal was leaking I had it in the shop for repair and the mechanic is telling me I need another rear axle housing.

Mechanic finally got the axle out because it was rusted on good. Anyway when he put the new seal on, what looks like a steel ring that goes in the tube first than the axle sit on the ring ....the ring didn't go in tight it could move around.

The mechanic said this ring should not move and the seal is going to fail and Because of that I am going to need another axle housing.

My question is....should this ring go in tight and not move in the tube where the axle goes?

He did get the seal on in the axle housing and no leaks yet...so is my axle housing shot after 228,000kms on it.

Why did he think you needed a new axle housing? I'm confused. There are three seals, one on each axle shaft, and one to seal the pinion shaft. Which one failed? JMHO, but at that mileage it would not be unusual for a seal to give it up.

The one that fail was the axle seal ....when the mechanic put the axle back in the housing there is a steel ring that goes in first that ring didn't go in tight it can move around in the tube or end of the housing.

Because this ring can move around at the end of the housing where the axle sits ... The seals going to fail again.

Mechanic saying this is the reason why I need another axle housing.

Dude, your axle housing is not shot, but your mechanic should be.
The ring is just to hold the axle straight so it fits through the seal without damaging it during installation.
Find another mechanic that is qualified quick...you are being ripped off.

Hey thanks for the heads up Rockclymer

So this ring ... Axle retaining ring don't have to be in there super tight so it can't move.

What you describe is on the front axle. The rear axle has the seal already on the axle shaft when it's installed into the housing, so no alignment ring like the front.

Gary,

Regarding the loose fitting "ring", are you referring to the bearing outer race?
It isn't a tight fit in the housing.

Here is what the service manual says about the outer race's fit in the housing:

"NOTE: Axle bearing race is a slip fit in the axle tube."

Thanks Ronjenx now I feel better knowing that it's a loose fit and I don't need another axle housing.

It would be nice if you had seen the fit so you would have an idea how loose it is.

I did see the bearing race in the tube housing it was not that loose to me. I try to turn it in the tube housing it was hard to turn, I made it move just a little bit, I could not get it to turn a complete circle. It was not that loose the mechanic still had to tap it in with a hammer lightly.
