I always had a feeling that the minute movement (moving a few thousandths of an inch fore and aft) in the shear plane there at the pin connection was not a good thing. I installed a hefty anti-rattle device thinking that it might just eliminate movement/jiggling in that area and it appears to have done that. Probably overkill and not needed but it gives me a bit of a "warm fuzzy" feeling.

Good times and safe travels.
