Neat, I find such things to be fascinating. I hope that all goes well finding a replacement and that the car is easily put back to pristine working order.
The rear diff on my truck is original, and to the best of my knowledge the gear oil has never been changed, it was the original gear oil put in by the factory workers during assembly. It would induce a slight bump when making slow turns (left or right), but now with fresh gear oil, it operates smoothly again.
The only thing it does not do properly is lock. The truck came with the optional G80 Eaton "Gov-lock" automatic locking differential (ALD). If it was working like it should, the diff would lock-up 100 percent, locking both rear axle shafts together, reducing axle shaft slip to zero.
Mine will try to lock, but fails to engage fully. It will let one rear wheel slip (spin) whilst the opposing wheel remains stationary. Basically its operating like a open differential. I suppose later on I’ll have to get it rebuilt. If I locked and unlocked as many times as it has, I guess I wouldn’t lock right either.
