Thanks Gary. My bad. I've never really paid close enough attention, I guess. I crawl under and lubricate it all a couple of times a year but I have never crawled under while stuff is going up and down to see how everything moves around. And, at the moment, mine is in storage so I cant take a look which I normally would have done before posting something. Good to know. I will certainly avail myself of the opportunity to pay closer attention when I get it out on the road in a couple of weeks. And I will also check for my own "scrapes". My brain IS slipping a bit and I suspect once I see it I'll say to myself, "well, I guess I knew that!" 
Thanks
Rick
