Wing pin grease

I have a v2Cx with 4 lift pins where the wings connect to the fuselage.

These get cleaned and greased with white grease on each assembly.

I'm noticing that the grease under the lift bearings gets squeezed out in flight. (Looks like maybe metal to metal contact.)

Is there a preferred grease to use there.
Maybe something with a graphite or moly fill?

SuperLube is super. Nothing comes close.

Thanks

You know I actually had some in the assembly box, but it felt too thin so I used the good old Lucas White. The SuperLube didn't pass the feels right test for grease that has served me well for wheel bearings for decades.

Reading today I learned there are two grease film tests.
Timken OK (ASTM 2509) for rolling bearings.
Four Ball (ASTM 2596) for sliding things like ball joints.

Super lube is a bit behind for rolling, but way ahead for sliding.

Lucus Extreme Pressure Synthetic Grease appears even better?

Today is clean out the white grease, inspect and put in the fancy stuff.


I continue to be amazed at the new things to learn with gliders.

Take a look at Lucas Red & Tacky. The Timken numbers are slightly better than the Extreme.
