How screwed is this axle?

So a funny thing happened today.... about 30 or so miles from home, I heard a thump thump thump. Brought it home slowly, took it apart, and found the attached pics...

2002 Grand Cherokee Limited
4.0, selectrak, bone stock. Just over 200k miles.

This is the drivers' side.

I'd appreciate any input. Thanks!

Your going to be needing a new one of those. Most likely the other side bearing is ready to go also. Looks like the seal was leaking for a while and the bearings ran dry. The level doesn't need to be too far down to starve those end bearings of lube. Your lucky it is a 4.0 with a Dana 35, finding an axle should be easy. The selec trac 44A axles are rare as hens teeth seeing Dana stopped making replacements.

You sure the axle is shot? Hard to tell from the pic if it can’t be cleaned up.

What’s up with the splines?

I think the axle itself is fine, no damage where the bearing would ride as the inner race is still in position. Get new bearings (do both sides) and seals and change your diff fluid.
Now is the bearing carrier on the axle housing replaceable because that look like it may be chewed up.

I'd be surprised if the new seal mated up with that axle very well.

Thanks guys - so new axle shaft, bearings and seals. Grease it back up and should be good to go.... Is this just connected with a pin in the pumpkin?

No pin. Axle just pulls out, it is held in place with the bearing and retainer on the outer end. You can get Richmond axles from Rock auto for around $145 each that come with a bearing, a seal and new lug studs.

uhmmmm...
but where does the retainer ring has gone? is it in pieces inside the axle tube?

Looking at the last picture, it seems that the seat seal is damaged, no more plain as it should be. It could be that the seal can't work fine.

^^ The retainer is shown in the third pic, the square looking part with the stud heads on it. That also needs to come out, it is what retains the seal in place. I am about to do this job tomorrow, or when the parts arrive. The retainer looks like this when not installed. The inner race of the bearing is still stuck on the axle as well.

I am looking at the damage on the axle just outside of the inner bearing race in this pic:


If you were to install new bearings and seals on this axle, I expect that it would leak in short order, and then you would have to start over with a new axle/bearing/seal anyway. So yeah, I would probably get a new axle/bearing/seal before trying to run this one. If your retainer plate is still in good shape, keep it because the OEM plates seem to be much better than what you can get aftermarket. Otherwise, get a new one and hope the retainer plate studs do not spin on you, or tack weld the studs to the plate before install.

Your parking brake shoes are saturated with oil, I guarantee your hand brake does not work worth a darn. It can be a frustrating job, but think about replacing the shoes while you have this thing apart. Clean ALL the old oil/grease out of the brake drum, I mean clean, clean, clean. I would probably just replace the brake drum/rotor because once that gear oil soaks everything it is very hard to get rid of, and if you are rebuilding the parking brake then why skip the drum?

Do not forget about the other side, it probably needs attention too.

Sorry, probably I have used the wrong words; I am talking about the locking collar that secures the bearing:


Where has it gone?

Could it be that the D35 has not that collar?

Thanks for the help, all! I got it apart and started to clean it up. This appears to be the race, right? The ring inside the axle. It'll have to come out, I assume? A buddy recommended that I get a slide hammer. Any better ideas? It's in there pretty good.

Also, ordered 2 new axles with bearings, seals, et al, and 2 quarts of the synthetic that Mopar recommends. 75W-140 I think.

I already bought new ceramic pads and brake shoes - going to replace all 4 rear sets.

I didn't see anything bad except bearing. Maybe something else is bad but it is not on the pictures.

I was wondering the same thing. The axle sets I see come with a bearing, seal and studs however no bearing collar included. When I look up bearing retainer the 44 shows the collar and the 35 shows the 4 stud plate, so maybe the 35 does not have them.

So that ring just inside the axle is supposed to be there and not removed? It looks like a bearing race to me, but then again.... I'm asking for advice here....
