I repaired my passenger side window again last night. I took the whole regulator out just to look at what the hec went wrong in the engineering of this thing!!!!!!
There are several weak ponts...
The window clips breaking is probably first thing owners experience.
The reglator design is pretty lame. When you watch it in action, you can see why it goes crooked. It's a lousy design destin to fail. There are three small points of contact made of plastic that ride on the vertical track and are supposed to keep things straight! They wear out and let the window go out of level when it comes up. This self loads the mechanism.. the more it pulls, the greater the resistance because the darn window goes crooked!!

I tried moving the regulator forward. I doesn't help. It's ALL in that little bit of play on the regulator arm. It doesn't amount to anything more than 2 mm at the arm, but out at the ends of the window, it translates into 6 - 8mm. Enough to make it jam.

Another regulator flaw is the fact that the arm can swing away from, and out of the regulator track!!!! Then the window gets REALLY crooked and things break.

It needs a complete redesign.

Well, I am a metal fabricator/welder ... hmmmmm.
