So I've been dealing with it since I have owned the truck and it only really becomes any sort of a noticeable issue when it rains. The back glass leaks from the top down onto the rubber seal and obviously down the back of the inside of the cab which I'm sure is not helping any sort of future rust issues. I don't mind getting in there and doing it myself but before I tackle a project like this I just wanted to hear from some of those you may have done it on their experience with replacing the seal on the back window and if there's anything that I should avoid. 72' ranger.. solid window

 

Not a hard job. Use a good razor knife to cut the rubber enough(outside) for the glass to be removed. The glass sits in a channel of rubber and if you cut the bottom of the channel loose the glass will fall out easily.

Put the new rubber on the glass, use lots of WD40 or PB to lubricate the channel and slip a piece of small diameter rope around the channel. Get a helper that can hold the glass against the rear of the cab as you sit inside and carefully pull the rope around. Making sure the rubber lip comes over the pinch of the cab window opening. Keep pushing in on window and work around slowly. Might take a couple tries, but it will slip into place.

I've typically only replaced solid glass with a slider, but it all works the same.

 

i always use a mixture of dish soap and water for seal , it won't wreak the rubber .
and leaves no slimy mess .

 

It's a cake walk.
You ask a question and get a poop ton of answers.
I use 5/16 cord ( rope not twine) lube up the body groove with Vaseline, two ends of the cord at the top of the glass. Pull the cord JUST hard enough to get the rubber to come to the inside of the cab. On the corners, slow down. By now you think you're comfortable to keep going. Slow down and WORK the cord around the corner to manipulate the seal into the cab. The Vaseline acts like a hydrolic sealant. 20 years and mine hasn't leaked a drop.

 

sounds easy enough. Now for a Sunny day

 

Applying some if this will ensure a leak - free seal.

It never hardens and stays tacky/pliable.

 

I guess a fella uses what he uses most.

 

Probably handy on date night, too: "now I know OCD folks make unrelated gestures prior to a particular action, but I assure you, wiping my finger around the back glass seal is relevant to the issue at hand, darlin'."

 

Mike, I was talking with one of the guys at SafeLite about what we used back in the day.

His reply was we don't use any soapy water due to possible causing rust.

I see where it could be a problem in the colder climates when installing with a rope.

Real easy job. Put the new gasket on the glass, Use a small rope in the groove, Set the bottom in place and slowly work the rope around the glass. The rope will pull the gasket into place.

 

when i replaced the rubber on my 67 .i put the molded joint at the bottom. just in case. thankfully my truck does not have the trim in the rubber. but i have the stainless trim on the windshield. i would also use soapy water. not wd 40,p.b.

 

Put the glass into the gasket, then put the trim into the rubber gasket before you put the glass into the frame.

 

 

Linky no worky, but I used 3M 08509 on mine. Nobody had it in stock locally that I found either, but O'Reilly's had one in like Indianapolis, so I had them get it shipped to them.

You'll need a caulk gun to apply it, but its the best stuff for this. The stuff they use on modern automotive glass isn't what you want, but all of the stores have it...
