Replacing W111 Sedan Back Window Rubber -- How Tuff ?

Well, my back window has been leaking for years now and water has done some minor damage, so I think it's time to do something about it. I've seen the rubber for pretty cheap nowadays so it's time to replace. Has anyone done this and what's involved. I know the removal is probably the simple part and I've done back windows before (not a Benz though) but what about the reinstalling of the chrome back there, or do I need to pay $200. at a shop. thanks. Later.

Pulling the cord.

Be really careful as the 40yr old glass is more fragile than new.

I would find an old pro to go slow and have prior experience, trim parts may need new clips if existing ones are rusty. remove window by cutting rubber with razor knife. fix all rust spots. headliner replacement at this time is recommended.

Even though removing the chrome trim strips attached to the rubber seems easy it is really hard, because they are aluminum and the bend very easy as you pull them out... You have to be careful when you remove them, take your time, go really slow and try not to "pull" them out and here is why: once you install the rubber seal on the glass then you have to install the chrome trim before you install the glass into place using the cord or weed wacker string. If the strips are bend they will keep on popping as you try to pull the glass in from inside... Everytime they pop you will have to stop, remove the glass, put the strips back in, straighten them and try again ang again and again... All day and close to all night trying to figure out what went wrong... they were coming out straight, but actually they were not because it seemed easy and you did not know how fragile they were... Well now you know!
The rubber is cheap it is the labor that is expensive and will drive the cost up. Once you do the rear do the front one too... Be careful removing the glue the factory used to seal the rubber to the glass and the rubber to the chassis... Hard as rock. You will damage the headliner edges as it is tucked underneath the seal... Unless you planning on replacing the headliner too... then you will need a sealer to seal the leaks between the rubber and the chassis around the lower corners, as gravity pulls water toward the lowest corners... The place it leaks now... You are up for a treat my friend! Good luck to you.

I paid $125 to have the rear window gasket changed by a professional. It took that guy three attempts before the gasket seated correctly. It was money well spent... After watching him do the job, I would rather pay than do it myself.
