While dissembling my passenger door window the nylon guide mounted to the front of the window pane bracket fell down. This is the nylon part that

slide up/down inside the front sash.

If loose, should this part be GLUED to the window pane bracket ?

It's normally snapped into place with 2 plastic nubs so just use a Heavy Duty Glue on it after cleaning both parts with Acetone or Brake cleaner. I had to do the same, works great now. Remember to regrease the hell out of it.

Thanks Dave. Great answer. Will follow your indication and lubricate generously after.

I don't mean to hijack this thread but is there a supplier of this piece? I've been looking for an hour on google, ebay, this site, MSA and zcarsource for one. My driver's side runner or whatever you want to call this thing is broken and the window falls out of the track and the regulator completely when rolled down.

Amazing. Only an hour ago I removed the window from my 240 to get at the door handle, and cleaned up and greased this very same nylon runner.

Any thoughts on making one out of a chunk of plastic on the band saw / scroll saw? I think aluminum or steel would be a pain, and probably bind in the track / oxidize, no matter how greased it is. If someone has a bottom window track from a broken window and this piece is intact, fire a PM over to me.

oranngetang, I have parts for you down in Calgary. PM sent.

If I may pile in on this discussion, albeit slightly off topic.

I am just in the process of reassembling the window mechanism, and as a couple of others have mentioned here that includes greasing the sash assembly.  When mine came apart it had an extremely heavy grade of grease.  This was stuff you didn't wipe off with a rag, but rather scraped and pried off.  It was real grease, but nothing you could ever run through a grease gun.  Is that kind of grease a factory installation that should be replaced with like, or is normal chassis grease OK?   

I would not recommend that. I have alway used white lithium. You can get it in tube or spray. I prefer the tube if you can reach where it needs to go.

Thanks - I'll heed your advice and go with lighter stuff.  But having said that, mine would seem to be one of those mysteries to be found in most close-to-half-century cars.  I have no idea why someone would install this hyper-heavy grease (meant for use on railway couplers?  I have no idea).

I suspect it wasn't that thick 40 years ago...

Or someone added their own. Was the car from primarily hot climate????
