If you had it rebuilt twice and the noise hasn't changed, it's time to look elsewhere...... I would take it to another shop next, what ratio is it? Why does it have an earlier pre1965 rear end in it? 1964 was the last year Mopar used tapered axles in the 8 3/4 rear ends, 1965 and later should have the later style flat flanged axles in it without the tapered axles   He mentioned tapered axles bearings, not tapered shafts. You would be correct, thank you

I saw tapered axles and not the bearings, OOPS sorry.   As far as the axle end play it should be more than .001 up to .005, no more than that  very, very little Use the adjuster to set it so you have no end play and then back it out a tiny bit, one notch at a time until you can barely feel the end and out movement of that axle

If you had it rebuilt twice and the noise hasn't changed, it's time to look elsewhere...... If you have a whine coming out of a differential what I've run into is improperly set pinion depth. And in the two case I've personally encountered, the noise was different under acceleration versus coast. If loading does not change the noise, I'm with slantzilla, time to look elsewhere.

Another topic posted on Moparts- " What tool did you wait too long to buy....." made me think of the wireless noise isolation-determination device. it has multiple hook ups- like microphones to place in various areas. Then while driving the passenger wearing the headphones listens to each sensor individually. The sensor/channel with the loudest noise is the area at fault. https://www.ebay.com/itm/314765649390

If you had it rebuilt twice and the noise hasn't changed, it's time to look elsewhere...... If you have a whine coming out of a differential what I've run into is improperly set pinion depth. And in the two case I've personally encountered, the noise was different under acceleration versus coast. If loading does not change the noise, I'm with slantzilla, time to look elsewhere. i will agree with the above adding deceleration to the mix. So, if the noise or pitch changes under any of the 3 conditions it is likely the gear set was not set up correctly. A noise on Decel is indicative of the pinion being to deep. the opposite is true under accel. I am not saying a hard accel or decel but rather a very slight increase either way while cruising on a flat road. Almost like adding or removing a feather from the gas pedal. I will also comment that the noise would likely not be noticeable with the wheels off the ground as there is no load on the bearings or gears. While the noise is present a Sharp L or R turn will usually identify a bad bearing as you load or unload the bearings while doing so. keep us posted

you ain't the only one that's chased noises, only to find they were "miles" away from where you thought they were coming from. that is why i have no hair on the top of my head...............  i see you are in Pittsburgh Jeff. i'm only 85miles north in Brookville.
