Alright guys, so I swapped out the axle today. Everything bolted in fine.

I know there's no axle in that pic, just use your imagination.

Apparently the donor axle had the wrong brake pads on it. I honestly don't see how the previous owner of the axle could've stopped. When I pressed the brakes the cylinders in the rear shot out the Pistons because the shoes were too small to contact the drum. So I swapped all the hardware and drums from the original axle onto the donor and I'll bleed the system in the morning.

And here is the busted original. (At least the pinion seal is good)

The gears inside look fine, there is no obvious damage or scoring I can see. All the teeth are there. Maybe someone here can chime in on this? When I'd let off the clutch the driveshaft would spin and it would let out a grind and not move. Maybe one of the splines have stripped? I'll look closer tomorrow.

Maybe something in the spider gears that u can't see, try spinning the pinion by hand or have someone spin one of the wheels for you and look inside to see what's going on, u can always post a video too

I spun it by hand and there is an excessive amount of play in the gears, but I couldn't get it to "grind" by hand. Everything seems to spin ok, but under engine torque something gives.

And on a separate note, here's the donor axle's brake shoes and drum. These shoes are too small, but unfortunately I didn't notice until the test drive last night.

I guess I should've zoomed out a bit, that's the passenger side axle shaft

The date code stamped onto the ring gear is from 1998. Apparently this axle was rebuilt not too long ago, but I wonder why the splines wore out so fast? The other axle shaft isn't as bad but it was close.

You're probably right, when I got this jeep it was obviously used as a trail toy, it was't close to street legal and any repairs or upgrades done to it were pretty sketchy. For example, the Reese hitch welded to the front crossmember. (Before being acidentally ripped out by yours truly)
