If your window is straining when you close it, it will need adjusting so it doesn't get overstressed. I think it is easier (or necessary) to make the adjustments with the door panel off. At the very least, the window stops need to be adjusted with the panel off. Be very careful tightening bolts, I inadvertently sent my passenger window crashing to the bottom of the door cavity in a bazillion pieces while tightening the "last" bolt.

Adjustments from what I understand are a bit tricky, just need a little finesse and patience. Good luck!
