Window out of track
 

Window is coming out of the track during closing. Side to side movement when beginning to close. removd door panel, cleaned and lubed window weather strip. Checked bolts for left and right track runners, all tight. Checked center track bolts, all tight. Checked two window bolts, all tight. In the middle of trying to adjust to minimize window movement by loosening bolts , fully raising window, tightening bolts. No improvement. Not convinced the problem is with the weatherstrip...dealer price is $100, found one at the local scrap yard but have not installed yet. Any suggestions?

If window is properly mounted, the run channel must be damaged and guides the window to leave channel. Replacing run channel should fix the problem.

good luck
