As part of the Piper PA28 annual inspection lubricating the bar
attached to the control yoke with engine oils is mentioned.

Beeswax works very well and does not run off. There's also a liquid Teflon
coating available at Lowes. Apply it and let it dry. Even a light coat of wheel
bearing grease works better than oil. Less likely to leave a mess.

Has anyone else experienced this?

The shafts on the Maule had to be lubricated every few hundred hours.
