Looks like it had no fluid in it. Cross shaft or carrier looks bent/broken, pinion is chewed up....that's ugly. I would just replace the whole axle Assembly.

Undo the pinion nut first, then pull out the diff and pinion gear, and inspect the bearings. If they are not shot you may get away with changing the preload spacer in the pinion bearing, otherwise you'd have to redo the pinion and/or carrier bearings. Pull it all apart and you'd see, it's not that all complicated after all.

Looking at that thing, I'm wondering what the heck has eaten the marks on the carrier? Looks like pinion teeth marks, but the pinion shouldn't be able to move that much towards the carrier if the ring gear hasn't lost any teeth. R&P set along with the carrier & spider gears are gone, and having that much damage on the gears will usually eat away the bearings in an instant because of the metal pieces floating around.

I would look for a new (used) front axle, you'd be looking at investing a lot more on new gears, carrier, spider gears and full rebuild kit + labour.

Yah, my guess is the carrier is split. Look at the cross pin, its not even square to the shafts. My guess is the pieces of the pinion were wedged between the carrier and pinion head I had similar marks with a broken pinion on mine before I rebuilt it.

My other thought is the pinion depth is too long, someone put a long pinion in a short pinion housing and just bolted everything together. Or the carrier bearings ate away to nothing and allowed the carrier to flop around

True.

I've had similar marks as you had, on an ARB locker - carrier bearing "post" on the locker sheared off, and allowed the ARB to move around. Weird thing is it didn't destroy the pumpkin or carrier bearing caps. I split an Eaton eLocker past summer on the area inwards from the ring gear. It caused a total mayhem inside the pumpkin, destroying absolutely everything.

Yup, that's why I went with the true track. Still keeps em both turning but much softer on the axle shafts and drivetrain

So I was finally able to get to the axle and get it out (took a lot of WD-40 & leverage) Now my issue is that I cant figure out how to remove the short stub shaft from the longer axle shaft. In the first pic you can see a C clip but I tried for about an hour to get it off with no luck. does anyone know a way to get these C clips off of the axle? And to be honest after looking at everything I can see how getting this C clip off is going to free the long shaft from the short one. Is there something that Im just missing here? Is there a better way to get these 2 axle parts apart?

Does anyone have any ideas on how this thing comes apart or how I can get this C clip off? I'm pretty much dead in the water now until I get this figured out :-/

Try hitting the c-clip with a punch or something. I've never taken one apart, but that is likely the only way to get it apart.

Yep, the front axle shafts are sort of a permanent connection. I've never seen a rebuild kit for the stock CV shafts, just full axle shaft assemblies. That would tell me they are not rebuildable.

If you need to run for awhile with the stub shafts alone, I'd look for snapped u-joint shafts or worn CVs from JY or on the forums. I'm pretty sure you could get two stub shafts with broken ears for free.
