Drop Extension Legs of Landing Gear Question

[fernsco]

Sometimes I really have to manhandle the landing gear leg extensions to retract (or extend)them. I had to use a hammer to tap them back up. The JT Stabilizer set screws are loose so that is not the problem. Would silicone or grease make this easier? Don't believe they are bent because we have no problem with the landing gear (okay, a blown fuse every now and then but have learned to cycle 10-15 seconds at a time and let the hydraulics rest).
