Replacing Door Rubber

Cars, W123 83 300D and an 83 300CD.

I am thinking that a lot of Mercedes famed door "thump" is due to the seals used on the doors. Regardless, the rubber on all 4 doors of the sedan needs to be replaced. Is this an outrageous PITA? Any special tools required? How is the current rubber held in place, fitted, adhesive? I know there are some clips involved here too from the diagrams in the Performance Products cat.
The coupe needs more extensive work, both door and all the surrounding rubber for the windows. Same questions apply. The coupe still has a pretty satisfying thunk, the sedan on the other hand sounds like a big tin can.
Advise greatly appreciated.

There's a channel that the weatherstip sits in for most of the door. for the rest of it you use special glue from 3M and clips. One thing though is you need to get around the door check strap

I redid the weatherstripping on my drivers door, it was pretty straight forward, and it does in fact bring back the solid "thump"

I replaced all four door seals on my 1984 300TD this weekend. It wasn't too difficult - I think it took about 3 hours for the entire project. Three sides of the seal are held by metal channels. The part of the seal at the front of the door and below the window is held in place by clips & adhesive. On the front door, there is also a metal strip that fits over the seal and is held in place by clips. I was able to re-use the clips on the rear doors, but the clips on the front doors are almost impossible to remove without destroying them, so I bought new ones (part# 000-987-10-15) - I think it took six per door. It didn't take any special tools, just a flat screwdriver, needle nose pliers, a hammer and something to clean the old adhesive off of the door. Also, putting a very small amount of something like ArmorAll on the edges of the metal channels will help to pop the seal into place - just keep it away from the areas where you're using adhesive...

I will be doing all four this summer on my SDL. Two are cracking and for now I am using Krazy glue to seal the cracks. It doesn't look like to bad of a job, most of the seal looks like a friction fit. Some will need to be glued.

Use only OE seals, the aftermarket seals are crap. I used an aftermarket trunk seal and I need to redo the job.

Can anyone recommend a source for the OE door seals? Does Fastlane do OE parts? How about Rusty? Is Performance Products seals of good quality? I'd like to do the job right the first time.

Phil gets stuff from a dealer in CA that sells stuff cheaper. Call Phil I bet he gives you a very good price.

I'll definitely be replacing mine. The driver door seal has a 1" gap of missing seal. It doesn't leak water but it makes alot of wind noise, especially with cross-winds.

Please let us know if you happen to find a source. I've been trying now to replace mine for 3 years.

Though I'll admit, I haven't been looking real hard in the last year and a half.

I could never find a 'new' source. And most used ones are in the same shape mine are in.



Edit: NM TD not CD.. still not awake yet.
