i will have to look again for the broken piece, or seeing if it has been deformed but still around the flange.
it is odd that this has happened with both rear windows though, while both fronts are fine. i think i also need to lubricate those rubber seals, making it easier for the regulator to move the window. perhaps the relative non-use of the rear windows allowed those seals to bind up, putting more stress on the piece.
thanks very much Victor.
I had this problem in my rr window. After pulling the door panal I discovered the following: The plastic wheel attached to the regulator that rides on the horizontal track was broken & had fallen off. It was formed around a small round steel flange rivited to the regulator. This may or may not still ride in the track, but it will move around too much causing the problem you describe.. Mine had split into 2 parts & was laying in the door. Why they didn't use a bearing for a part that takes so much stress is beyond me. The track in question has an adjustment screw on the right side to square up the window when it is closed completely. The left side of mine was riveted on.
I drilled out the rivet & removed the track. I was able to use stainless safety wire to tie the nylon wheel back together and onto it's mount & it should work for a while longer. The rivet on the track I replaced with a machine screw & elastic stop nut. The track had to come off to get the wheel back into it. I am going to find a bearing that's the right size & replace them. I suspect this is a common problem & sells lots of new regulators.
