I am in the process of replacing the rear shock absorbers on my 2002 Escape and am confounded by the procedure for the removal of the interior rear quarter trim panel to gain access to the top of the rear shock. Specifically, I have been able to get the rear trim panel free up to attachment point at the lower front of the panel. This point is underneath the back of the rear sill point. At this point both of these panels are held by a white nylon pin of some type. I have freed up the sill plate, but can't figure out how to free up the rear trim panel. I would appreciate any suggestion.
