Well, I tried spraying with a "dry teflon" lube in the seal channel. It maybe helped a little. This kind of confirms my suspiscion that theglass sits a bit too far to the rear. Unfortunately, that seems to be the one dimension that's welded in place. I think I'm going to accept this as "close enough".

BigBlue, On the 4 door sedan, there is a door frame that the glass slides in. I can play with the motor either door open or door closed & get the same results. All my disassembly in on the inside of the door, outside is solid. I know what you mean about the "felt like". It's kind of a fuzzy coated rubber.

Sounds like no one has cured these ills before.
