Guys: I'm still working on my 2nd condition inspection and I have a question for the group concerning the flap drive. First, it is functioning fine, I need to know if PM is required to keep it this way? I have read and am familiar with the Van fix for too much grease in the motor, but is there a dsassembly, clean, inspect and lube procedure I've overlooked. I'm inclined to "not fix what ain't broke" mode unless the group convinces me otherwise. Thanks in advance, Dan.
