I got replacements for these but never did it before, share the secrets please…. These are hard as a rock.
I put my window down a little bit and pushed it straight down. I did use a tiny rubber mallet with a small punch tapping the seal at the track (carefully) to just start it. Once it gave it came out fairly easy. A tip on buying new ones, make sure to get the one with the metal in it. I accidently bought the all rubbers and they were terrible, they spread out and stopped sealing pretty fast.
I also need to replace the chrome pieces, not just the rubber seals. I have them, but haven't tried anything yet
When I did mine I laid the Glass itself in the bed of the pointing at the sun on a very HOT day.... Removing them was still a royal pain. Heat is your friend...... Putting then on was a piece cake.. The way mine came off I don't think it can be R&R in place.
