The scoring on the drive side of the pinion teeth, the metal fragments and the lost wire insulation all suggest to me that things aren’t right in there. Where are the fragments from!?

I should’ve mentioned that when I bought this axle it had a spool and one of the pinion teeth was badly broken. Actually two or maybe three were broken and that scoring was on the case prior to my purchase.
For the life of me I cannot find where those fragments have come from.
Here’s a video of the ring gear
When you clean the races do the marks on the races go away? There is enough metal in the rear end that there should be an obvious piece that is failing. I would look at the pinion bearings.
Races cleaned up and pics in prior post.
We also turn the jeep on and ran it while listening to the pinion bearing with a mechanic stethoscope and gave it gas and let off and it seemed smooth. It’s hard to see if there’s anything wrong with the bearings. I guess I’d have to remove them
Driving straight with the axles at the same speed the differential should not make any noise. Is that tooth compromised?
I think it’s just the angle or a reflection. Here’s a new pic of the same tooth.
YouTube allows you to slow down playback to .25 speed. The video appears to show the noise is pretty much the same place on every rotation. The pinion bearings are pretty much the last thing. The only way to truly see is disassembly. Do you know if it has a solid spacer or a crush sleeve?
We looked in the locker window and rotated the teeth inside as much as we could looking for chips. Looked in the splined sides too. All that’s strange is a bit of rust or rust color on a non-moving face.Can you see anything inside the locker? I'd be looking to see if the shorting wire caused the locker to randomly engage and disengage at speed, leading to something inside chipping.
The pinion bearing is the last thing. I’ll correct the wiring, of course, but I think I’ll have to have someone else pull the pinion bearing. I could pull it, but I couldn’t get it back to spec. Thanks for help.
Ok.... I'm sure I'll get the idiot of the day award here but.....would you do damage to the rear end if you took it for a short test drive?We looked in the locker window and rotated the teeth inside as much as we could looking for chips. Looked in the splined sides too. All that’s strange is a bit of rust or rust color on a non-moving face.
I was just going to suggest the same thing, BUT without the carrier there isn't anyway to install the axles so no way to install the rear tires. So the short answer is NO he can't take it for a drive the way it is.
Without the rear carrier in? I wouldn’t think so. I don’t think it would see any load.
If you are talking about removing the locker, the axles would flop around, no bueno.
The 44 is attached at the end of the axle not a c clip like a 35. My worry would be the slop in the housing. (Inner axles)
Don’t think it can be done. The carrier bearings are crushed on the locker/carrier.
