I've gone completely through the forum and know that at least a couple of people say they've replaced the upper weatherstrip that goes around the sides and top of the back window on the tailgate/hatch. But I cannot find instructions on this site, on YouTube, or on the Internet at large for how to do it. That includes from the Service Manual I downloaded from the sticky here. I did read one comment that said the window had to be removed because it uses this weatherstrip as the running track. But I don't know if this is actually the case since the window rolls down and the weatherstrip (Part# 68275-35020) only extends about 4 inches below the door.

So can anyone tell me what needs to be done to replace this part?
