probabbly from stepping out of the car, I’ve somehow dislodged the rubber strip by the tread plate. (See photo) Seems like there should be an easy way to snap it back in...I just don’t know what it is🧐 Any tips to tricks?
Thanks

Mine is doing the same. There are small plastic pins that insert into holes in the metal of the body at regularly spaced intervals. Some of mine are broken or the hole the rubber sits in is cracked at the edges. Some of the pins were pushed into the rubber. In short, either need new pins or new weatherstrip that hopefully includes pins. If your pins and rubber are not damaged you may be able to reset the pin in the rubber and snap back into the holes. Unfortunately this will likely reoccur even with a replacement piece. I posted on this about a month ago but didn't get a response other than Unhinged asking for a photo of the pins. I was thinking of maybe using an adhesive but wasn't thrilled with the idea of smearing up the body. Maybe a dab in the pin holes of an automotive adhesive or a thin 3M peel and stick. Any suggestions welcome as I was contemplating this just yesterday. Leaning towards a 3M tape, but haven't researched.

Hhmmm.....I did see what looked like some sort of pins but didn’t see any way to make them work...maybe broken. A few small strips of 3m might do the trick to hold it back in place. I most likely over time kept kicking the strip on my way out of the car.

Longevity is why replacing the rubber and pins doesn't seem to a good future proof solution. I'm thinking 3m tape too.
