Same here - got in there, bent the track some, greased 'em up good with white lithium after the silicone didn't do much. Next thing ya know I put them up and the track rubber came out of the door with the glass and ripped in half. Still need to go in and fix that right. But they sorta work. I still have to help them a bit since they still bind. I don't think it's the track, I think it's the lift mechanism and the lift point placement on the glass. This would be a good project for me tomorrow.
