Thanks for the well educated response,

Thinking about it, I know it has some supended teflon it it and who knows maybe some silicone lube too.

It does seem to work good for a lot of the smaller stuff.

I am trying to put in all MS ball bearing rod ends in my controls, but I might run out of money first they are a little pricey.

Tri-Flow also makes a "dry" lubricant that leaves less residue behind than the regular "wet" stuff. I've used it for years on bicycle chains and it makes them last much longer.

Question Do rod end bearings need lubricating?

After 16 hours of flying, I could feel some drag in the ailerons during control inputs. I traced it to the rod end bearing on the bellcrank leading to the right aileron. I removed the bearing and could not rotate the ball with my fingers. Inserting a punch in the bolt hole, I rotated it and sprayed it with penetrant/lubricant. After a little working, it now rotates freely with light finger pressure- just about spins actually. Inspecting the ball, there are no scratches, just a little polishing around the circumference at the mid diameter (the equator, if you will) of the ball. There is no indication that there is a possibility of failure, but I suppose it could end up dragging again if lubrication was not a long term fix.

Question to those in the know is; should the rod end bearing be permanently lubricated, or is it a common practice to occasionally lubricate these? Is wheel bearing grease acceptable or should a white grease like lubriplate be used?

I'm pretty sure I know where the problem originated. Years back I had someone in my local chapter weld the threaded portion onto the tubing, since I didn't like the rivet idea on these critical push/pull tubes. They didn't remove the bearing and I think it cooked the provided lubricant. I'll be inspecting the 3 remaining bearings. Bit of a setback, but so far the only problem identified in the test program.

Default Short Answer, Yes

I use LPS-2 on protected ball joints (inside the fuselage, wings, under the cowl) and LPS-1 on external ones (like rudder, elevator).....
Frequency depends on operating environment.

I was taught to use LPS-2 on my old Bonanza and have continued with the RV-10. I had one beginning to squeak a bit a while back, so now check frequently.

Default Mooney calls out

Triflow on all the rod end bearings. Worked well for me. You can get it at bicycle shops and some hardware stores. I'm now using on my 7A...

That lubricating tool is just too cool. Only problem of course is you have to disassemble the joint. LPS-2 is what I used to lubricate it in the first place.

I used to use LPS-2. I now use TRIFLOW as recommended by Mooney. It's a bit pricey, but worth it in my experience.
