A couple of months back I had to have the rear off-side halfshaft oils seal replaced on the back axle which is the D44 on my TJ.

A week or so after oil started to pee out of it again, so I took it back to the place where I had the original work done and they stripped dismantled and reassembled it again and the seal has kept the oil in since!

Today whilst adjusting the rear brakes, I noticed that there is about 1mm of end float in the half shaft which had the oil leak whilst on the other side, there is no apparent end float.

I recall the bearing retaining ring on the half shaft was well seated, so anyone any ideas why I have this end float on one side and not the other?

i would say the bearing retaining coller has not quite been pressed home alowing the bearing to be  a smidge sloppy but thats just my thunking on it

[PtP]

The bearing retaining collar was pressed on as far as it could go from what I recall and saw, but I also suspect this is the problem.

If there was dirt or rust behind the retaining plate which bolts onto the end of the axle, could this also cause the same problem?

[Bubba]

they are stubborn feckkers  and often need a good thwack using a thick tube and copper coller to seat them that last smidge you may be on to somthing about the dirt but i cant see them not giving it all a good clean as it was a second atempt

I'll take a look!

I’ve had a look today and the collar was pressed well on the half-shaft, but I discovered plenty of rust, mud and general crud between the axle end face and the back of the brake back plate. This crud was preventing the surfaces from mating cleanly together, thus allowing the extra end float. The surfaces were all cleaned off and coated in waxoyl. Once everything was reassembled the extra end float disappeared and I was just left with a very small amount end float which I think is acceptable.

well it would seem the firm that did it beforehand may not to be the best

You could be right.

Although, I did just ask them to replace the oil seal which involved replacing the bearing as well. I guess they should have identified the excessive end float and investigated it though.

Thread revival time  

On the rear axle on my 95 XJ 4.0L I have noticed on one side about 1mm end float and the other side about 3mm end float no oil leaks, I was just wonderin what its supposed to be.

Took my axle to local dealership and they said it was ok and most cherokees were like that and it was not a MOT failiure...........I feel a fob off there but I dont know???

Any thoughts

Yours is a dana35 rear axle which has a different way of retaining the driveshaft to the dana44 in PtP's

I have 2mm play in both shafts in my 35, I wouldn't worry about it. I can't find the endfloat limits set by dana anywhere, does someone else know it?

Alex end float

I’ve had a look around and found this http://www.willystech.com/faqs/Breakout ... html#ASEFM

Hope it’s of some help. Everywhere I look it talks about the Dana 35 having lots of end float.

Also found this for the hardier off roaders with deeper pockets.

its normal so long as theres no lift in the bearing its cool

Cheers guys

I have deep pockets ............................................... but short arms

Theres no lift ie the bearing is ok, just movement in and out.
