Yeah that spacer sleeve.
My thought is, that if worn short it might allow the hub to sit further inboard. By just a little.
But I’m not sure of this being your problem. The spacer only locates the inner race of the outer roller bearing.
Yeah , something isn’t spaced right. The backing plate mounted without any warpage? And sitting right on the bearing housing?
I admit, obvious questions :-)

Now I have new bearings and new backing plates, and something is not spaced as it should. I had a machine shop do the GW bearing kit that has inner and outer bearings and seals. I seem to be coming back to the backing plates. I am going to pull the drums today, paint over the marks on the plate, and drive again to see if and where it is rubbing.

Then did new trailing arm bushings, and in the process saw the backing plate was rusting through, so replaced the backing plates, and that is when the scraping started. There are still some scrape marks on the backing plate, but before I grind off more metal I want to be sure I am going in the right direction.

The slight noise in addition to the turning noise followed tightening up the axle nut, so I think my issue is still the brakes, but running that by people for comments before I risk damaging the drums.

I hesitate to grind any more material off the drum until I have a better idea what is happening. Grinding down the edge did help at first when it was a constant rubbing noise, it eliminated the noise except in a turn, but subsequent grinding has done nothing. Now, there is a new and slight repetitive noise that is in sync with the wheel rotation that makes me wonder if now there is a CV problem not just the brake problem. I am able to move the CVs slightly back and forth by hand and there is no unusual sound when doing that, and nothing looks out of the ordinary. Knowing which side is likely involved will help me focus my efforts.
