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 scope work


He mentioned tapered axles bearings, not tapered shafts.


... and it's 3.23 gear .

No hum off the ground , if it's in the rear that would have me checking the axle bearings , is the endplay set right ?


Axle specialist in my area used to tell me that sometimes just touching the brakes - if the noise diminished and returned after letting off the brakes would be another way to see if the rear wheel bearings were at fault. The drum would “pilot” off the shoes and relieve pressure off the bearings. I just used the hard left and right maneuver to test the bearings.
