Hi all. My hand-crank windows on my ‘84 FJ60 are pretty hard to operate, especially the driver’s window. It’s a great workout, but I’m actually going for tone, not bulk, right now. So I’d like to fix it. My hunch is the window felts should be replaced (see photo). Should I keep an eye out for other sources of this issue? Also, any resources out there on how to tackle this project? A basic Google didn’t give me much in the way of specifics. Thanks!
