    My passenger side glass pops out of it's rear channel when I roll the window up. It occurs just past the halfway mark. It does fine going down. As mentioned in a prior post on this problem, I tried rolling the window up then loosening up the glass channel bolts then rolling the window partially down and then retightening the bolts. I tried other variations of this technique but nothing works. Anyone have an idea? I can't se any other adjustments other than the rear bolt holding the regulator to the door has some adjustment. I played with this as well and got the same result.

    Sounds to me like you have a window rivet not holding the glass to the rail on the regulator.

    Checked that. Looks like it's in all the way but I'll look at it again tomorrow.

    Arrrrgggghhh!

    :huh:Window rivets are fine. I spent another hour playing with this today and am my wits end. Something to add to my original post is that when the window is fully in the up position there is a gap of about 3/8 inch at the front/bottom of the window. The entire window has to be sloping from back to front in order for this to happen...right? Has anyone else seen anything like this? :anyone: How can something so simple become so complicated?

    Maybe the rail is riding on worn out or broken rollers? It has to be something pretty simple I would think.

    Thanx guys. It has to be something simple. I think i'll take the glass and regulator out tomorrow, clean the hell out of everything, inspect the rollers and relube everything. The shop manual says to use polyethylene grease but have no clue what that is. Would white lithium grease work?

    Not that long ago, I had mine apart (driver side) and there is a bolt that holds the lower part of the front track to the area of the door where the hinges are. If that bolt was missing, it might give you the problem you are experiencing.

    Years ago when I worked at a Ford dealership we had square nylon "rollers" to replace the typical round ones. The square ones fit inside the channel in the regulator. It needs to be well greased but I thought them superior to the round ones as they held better in the channel.

    Today I removed the glass and window regulator. The rollers looked fine. Nothing looked loose or worn out. I cleaned everything thoroughly then lubed the rotating parts with Marvel Mystery Oil and then applied a generous coating of white lithium grease everywhere. Once I reinstalled the regulator it would roll up and down with virtually no resistance. Next I reinstalled the glass. The glass still pops out of the rear track about half way up. It's fine going down. It's easy to push the glass back in the track and complete the roll up. All of the waist seals and window track seals are brand new and quite tight. I guessing that maybe all of the friction generated from the new seals isn't causing the problem. I tried all of the advise given in the previous replies. Thanks to everyone for the suggestions. I will do the other door this weekend. Hope that one goes better.

    I made the original post back in April. At the time and out of frustration I decided to leave this problem alone and move on to other things. To review, my passenger side glass pops out of it's rear channel when I roll the window up. It occurs just past the halfway mark. Everyone gave me great advice at the time but nothing worked. Tonight I put the regulator back on the bench and saw something I didn't see before. The holes in the rail that the window attaches to are different. One end the hole is elongated while the hole on the other end is round. Is this from wear or are they supposed to be like this? I had two other rails and the holes look the same, one oval and one round. If this is the way it's supposed to be then which end goes where?

    While I'm asking questions I wanted to confirm that the right and left door regulators are identical. Right?y

    I just went out and looked at my stash. The elongated hole goes toward the rear.

    The regulators are side specific.

    Thanks Craig! Regarding the difference between right and left. I put them side by side and they appear identical in every way. What am I overlooking?

    They should be mirrors of each other
