What type of grease do you use on cessna airframes. The manual has a bunch of different mil specs but says they "are not mandatory". I have seen a bunch of people use wd-40 a lot. I have never seen powdered graphite for the piano hinges, and some people have recommended LPS-2 for hinges, pulleys, etc.. What do you guise usually use to lubricate various airframe components?
 
Grease: Generally whatever milspec is called for. Usually Aeroshell 7 (MIL 83277) on stuff like torque links and trim screws, Mobil 22 (MIL 81322) for wheel bearings, Aeroshell 5 or 6 for props (depends on what the overhaul facility used).
General lubricating oil (usually called out as MIL-L-7870): LPS2. Usually goes on stuff like piano hinges, pulley bearings, eye bearings, etc.
Silicone ONLY on Lycoming starter bendixes.
Grease-based anti-seize on brake caliper pins.

I think that's about it.
 
Aeroshell 5 on normal grease fittings
Aeroshell 17 on flap jackscrews (Some Cessnas require it per AD)
LPS2 or spray graphite on piano hinges & rod ends.
LPS1 on Yoke tubes and seat rails.

Don't the stupid Cessna retract singles take some special grease on the landing gear actuator gears? Like Aeroshell 33 or something?
