87MJJeep Posted May 7, 2020 Share Posted May 7, 2020 My paint guy needed to remove my rear window to do a clean job. He found some rust in the lower corners, so it's good he called a glass guy to remove it. The removal process ruined the seal around the window. I had put silicone around it many years ago. I don't know if that made the removal harder or if the seal would have not survived either way. Here are some photos. I always assumed this sliding window was aftermarket, but I don't know. Whether factory or aftermarket, does anyone know the simplest way to replace the seal? The glass guy that pulled the window said he doesn't show any part listing anywhere if it is OEM. And he is concerned about finding a correct seal if it's aftermarket. If getting a good seal is not possible, are there any aftermarket rear window kits to purchase for these old trucks? I like having the sliding glass to open, but I could live with a solid piece. The glass guy said he can cut a custom piece, have it tempered, and then install it. The rough estimate is $250. I just hope someone can give me good advice for replacing the seal. Link to comment Share on other sites More sharing options...
jdog Posted May 7, 2020 Share Posted May 7, 2020 looks aftermarket, if so I believe the only company doing that is cr laurance, the last time someone tried to talk to them about parts they would not have it and wanted them to buy a whole window Link to comment Share on other sites More sharing options...

Smokeyyank Posted May 7, 2020 Share Posted May 7, 2020 It does look aftermarket. The one MJ I just sold I had to replace the rear slider with a CR one that I got from another member. Fit sucked but I didn't have a lot of options. My old seal did not fit on it. As for a seal you're at the mercy of a used one. No one makes them.

Pete M Posted May 7, 2020 Share Posted May 7, 2020 MJs only had solid and 3 piece windows. that is most definite;y aftermarket. Link to comment Share on other sites More sharing options...
87MJJeep Posted May 8, 2020 Author Share Posted May 8, 2020 Thank you for the added replies. Smokeyyank, Can you tell me more about the bad fit of the CR unit? Did it look bad or was there any leaks or more potential for leaks down the road? I see the installation note for the CR window is "requires urethane adhesive." Looking back, had you had a standard 1 piece glass laying around, would you have wished you used it instead? Or was the fitment issue worth dealing with to have an opening window?

I don't have a picture but this is from Limejeepers build. Basically there is no seal around it and there is a slight gap about 1/4 in between it and the body. It just doesn't sit flush. You'd have to put a bead of silicone around it to prevent water from just sitting. I did have a temporary one piece window in there but preferred the slider because that was the only way to get some airflow in that hot box of a cab.

Eagle Posted May 8, 2020 Share Posted May 8, 2020 The slider you have is aftermarket. The factory unit had a single sliding pane in the center. Your glass guy canNOT cut a flat piece of glass to fit and have it tempered. The factory rear glass is curved, not flat. As others have already stated, the rear window is installed like a windshield, with adhesive. What you refer to as the "seal" is just rubber trim, like on the late model Cherokee windshield. If you can't find a new trim gasket (which you probably can't), my suggestion is to use black RTV sealant. Cut/grind a plastic or metal putty knife into an arched profile, glob on the sealant, and use the custom puttu knife to shave it down to a smooth, slightly domed profile before it sets.

87MJJeep Posted June 3, 2020 Author Share Posted June 3, 2020 @Smokeyyank and anyone else that has used the CR sliding rear window, did you follow the instructions where 6(?) holes are drilled in the cab for screws to go through and into the rear glass frame, or did you just trust the urethane to hold it in place? My shop's owner said his glass guy will probably just use urethane and ignore the screws and instructions that came with the unit. I'm curious if that's a wise or not.

Pete M Posted June 3, 2020 Share Posted June 3, 2020 Pretty sure my 20 year old CR was simply urethaned in place. so far so good. Link to comment Share on other sites More sharing options...
Gjeep Posted June 3, 2020 Share Posted June 3, 2020 You will need to drill the holes. I was doubtful and thought I could do without the screws, but I would have been in a heap of trouble if I wasn't able to quickly mount them as the urethane was drying on my '89 MJ's CRL rear window. These screws pull the aluminum window frame in so it sits as close and evenly to the body as possible. Before I put them in I was going to have a very uneven gap around the window. Would have looked horrible. Like I said -- suggest you pre-drill all the holes for the screws. BTW - that window you pulled out was a first gen CRL window with separate gasket. They updated the design to LimeyJeep's pic. Link to comment Share on other sites More sharing options...
87MJJeep Posted June 3, 2020 Author Share Posted June 3, 2020 Thanks for the replies guys. I'll tell my buddy and ask him if I can speak or email/text with his glass guy before he arrives to do the work and make sure we're on the same page. That's interesting my old window is their first gen! Link to comment Share on other sites More sharing options...
Smokeyyank Posted June 4, 2020 Share Posted June 4, 2020 Mine was urethane only but it fit like poo I could see where the screws would be need to "hug" it in. Link to comment Share on other sites More sharing options...
