I can't think of a drum brake component that would cause a squealing noise
that usually has a dragging/grinding noise.
Is it only when you apply the brakes?

Thanks! Yes, only when the brakes are applied - and only under intermediate braking. Light or firm application of the pedal keeps things quiet. It's pretty clearly a brake noise, or sure seems to be - if I ease up on the pedal from a complete stop so that the truck inches forward, I can get a "stutter-squeal" from that right rear brake.

I would expect a dragging/grinding noise from metal on metal. Maybe I'll have to get a video with the squeal so you all can hear what I'm talking about.
