The three small bearings that support each yoke at the panel in my 337 have lost their rubber coating. At least I think they are supposed to have a rubber coating.
In my aircraft, these bearings are part #S2010-3. Cessna is very proud of these little bearings, wanting in the neighborhood of $150 each. (That a pretty exclusive neighborhood. )
I found a place that will repair or exchange these bearings for $50 each, 1/3 the price of new. It is
Robair (

This guy has developed a business making and selling common Cessna parts. I used him a couple of months ago when a part of my seat broke. He had a beefier replacement, complete with PMA (or STC, I don't remember now) for 1/3 the price of the OEM Cessna part.
Hope this helps some of you.
