It is hard to say, but thinking about it now, maybe it was as mentioned above, the one drum that was loose (likely replaced at one time) isn't balanced with the hub?

I wonder if a brake lath would pick it up as a assy doing a really light cut? Mitch what you think?
I know who would know how to balance them Craig @mobileparts
@MOPARMITCH
With a brake lathe, would you need to cut inside and out to bring it more concentric or how would it balance it? I haven't had coffee yet....
Might show more chattering on a super light cut? Maybe. Back in the day in the shop I worked in they had this funky strobe light and like a one wheel dyno roller set up. You spun the tire and you pat a mark on it. Somehow it showed if it was balanced as a wheel assy or not. Old school stuff there.
Kind of like this.

It makes sense and I have seen road balance also since when there is weight on a wheel, it rides and balances differently.
LOL it was this
Something like this to balance a rotor or drum?
Wonder if any old tire shops still have one? You do have to mark the drum, wheel to the hub so if taken apart it goes back on the same position.
it could work, but I think it would take a bunch to try and sort out where exactly it is heavy and where to put the weight and how much weight
I used to cut a lot of brake drums and brake rotors when I was in the parts business. If you mount a drum and hub and try to make a light cut on it you will find out if it's out of round. Depending upon how far out of round it is it could be cut round again. But if it's out of balance you really can't tell that on a brake lathe
I really do not know how you check a drum and also a hub separately. Wait on Craig sure he has been through this.
I don't know, it is an interesting thought.
Does anyone know of new 10" hub/drum assemblies just in case?
Hub and drums should be checked as an assembly.
@mobileparts parts for good NOS ones is all I know of that is fair. The new drums suck for sure.
I need Front hub/drum assemblies

The 71 right? By chance you have part numbers?
Run the shoes eat the import metal fast. Seriously
Yes 71, but no I don't know the part numbers
If you get them from My Mopar PM me them I can check the NOS database country wide.
