I'm having similar issues. I've been running All-Pro upper arms for 5 or 6 years now and I don't think they've ever worked correctly. Not sure exactly where the problem is, but at this point it seems to be a combination of things. The inner sleeves seem like they're too short. Whether they came like that new, or have worn over time I'm not sure, but I can't get the bolt/nut right enough to "lock up" and allow the bushing to slide on the inner sleeves. Currently all my rotation is between the long bolt and the inner sleeve. This has normally drags the washers against the frame mount which slowly cuts in to the washers, sometimes loosening the nut allowing even more slop. I replaced the washers a year or so ago, and still couldn't get anything work properly. Arms seem like they've spread open as well. You can see in the video below the large gap between the bushing and the washer. This was tight when I put those new washers in a year ago. Without adding even more washers I can't torque the nut down to squeeze the sleeves tight without it deforming the arms and putting so much bind into the bushings that nothing moves nicely.
Some pictures from last time I messed with this. That upper control arm bolt was seized in there and it turned into almost a 24 hour battle to get it out...

Cut the bolt

After beating and air hammering the section of bolt stuck in the frame

Welded washers to the bolt stub and with a pipe wrench I was able to twist it out. This is the "front" of the bolt

Tried the same on the rear. Not sure if all the beating made it brittle, or deform so much it was extra stuck. No welding of washers or nuts worked for me

Trying to push it out with a clamp which later exploded in my face when I over tightened it. Removed the "front section" of bolt by drilling halfway through the tube and bolt

Success??

It got ugly. Welded a patch over the hole I made and reinstalled the arm with those huge washers. Forget the measurements but I ended up with like .325" more washer thickness to get everything sitting nice. That was a year or so ago and everything is fucked again.
