A couple of updated tips...
1. Restating the above. - on side doors position your new tabs over the slots they need to fit into before you start pressing down to seat the entire belt molding. It presses on very easily so just get it aligned well right to left first.
2. A felt edge squeegee tool is ideal for this and including the rear hatch belt molding. Th e non-felt edge is soft and tapered. Once it is pushed up it will actually snap the side door belt moldings loose.
It will also pop the clip on the end of the strip right up. No issues at all. Just insert and push. You will hear the little snap sounds as you go. Then just slide it down the line. Then with both hands just pull up and roll forward on the entire strip.
3. Rear Cargo Door. Same felt squeegee but this time push it as far up as possible. You may hear a "snap". At that point the trim is still not loose bu the squeegee make a big space. Now with a wide pry tool wrapped in a rag push it up towards the roof and pry it a bit. You will hear a "crack" sound. Louder than the "snap". Do that the entire length.
Do not start in the middle. Start between the middle and either end. Do those areas. Then work towards the middle from both sides. The middle seems tighter for some reason.
My piece came off intact and could be reinstalled if need be.
On the front door pieces if you are saving them for emergency fix if they are not already torn up.... the point where strip joins the section with the rubber wiper will crack if you pry/bend it up very much at all.
So overall if you want to save these things or if happen to be doing junk yard pulls. You don't need to deform them much to get them off and the little 4" section with the clip will break where it joins the larger section with wiper so don't bend that area if you help it.
Possibly the easiest fix you could ever do. Here is the tool that seems designed for the job.
ebay link may expire. Just search plastic felt edge squeegee about $3 - $5. I suppose the plastics could vary. Mine was white and stiff but soft pliable tapered and rounded plastic front edge..... unlike the hard plastic auto pry tools.
On the rear hatch my big pry bar was actually a 18" metal one. But you don't really pry with it. You just want something wide with a somewhat dull edge ( wrapped in cloth ) and long enough to push upward in the gap the squeegee makes. It just pops those catches the last little bit.
