The weather stripping on both suicide doors of my truck has started to crack and fall apart over the past few months. My local dealer wanted ~$150 to replace the two weather strip assemblies, so I thought I'd have a crack at it myself for just the cost of parts (2 x $25/ea) through their parts department.
Unfortunately, the process of removing the old weather stripping is non-obvious to me. I'm not sure if the old parts are simply removed by force, there is some technique or trick, or if I need a special tool. I've spent some time on Google and the forums here, but the closest I've come to a solution is this thread: http://www.fjcruiserforums.com/forums/interior-exterior-visual-tech/132236-what-do-you-do-about.html. I could just snap them off by force, but I'm worried that the plastic cone bits that snap into the door would break off inside the door. Does this require taking the inside door panel off?
If someone could help to enlighten me as to how to remove the old weather strips, I would greatly appreciate it. It looks like once they're off the new ones will snap right into place, but if it's more involved than that I'd be happy to hear about that as well.
Finally, here are some pictures to help illustrate what I'm talking about:
