Winegard caravan antenna / aerial repair. No more bouncing

Our long-suffering and well punished Winegard tv antenna now bounces as it's being lowered. The more the winder is turned, the more it bounces, requiring us to stop winding it down 2 or 3 times to allow the bounce to stop before eventually lowering it to the roof. Worn components resulting from grinding against each other are overdue for attention. Some very simple and cheap techniques along with minimal tools and parts (salvaged from the bin) have reduced the annoying bounce and extend the service life of our Winegard's winding mechanism indefinitely.
