Also bought Cherokee side door panels. Wondering if taking off the existing Liberty panels will be a pain or not.
Not really a pain but takes a little time. The factory adheasive is strong!
I used a hair drier to soften the adheasive behind the trim. Then I used an old credit card to pry it away from the door enough to grab with my fingers. Continuing with the hair drier and SLOW steady pressure, it came right off.
There will probably be some adheasive that remains on the door. Adheasive remover cures this, then I used some brake cleaner on a rag before installing the new trim.
Fight the urge to rip and tear. Slow and steady wins this race.
