Depends of who the manufacture is for your stabilizers. Power Gear says to clean the chrome cylinder and spray it with silicone. Also on some Power Gear leveling systems there is a Zerk fitting on each leg right about where the chrome piston enters the jack body. Mine are like that. I pump a small amount of lithium grease into these a couple times a year.
I know other manufacturers use other types of lubricants.
