Just did mine the other night for the first time. I did find one zerk (on the outrigger foot) that wouldn't take grease and the little bearing was gone. Went and bought a new one, cleaned it up and installed it. The foot was pretty dry and still wouldn't take grease. I hit the whole thing with some WD-40 and used a hammer to tap the shaft back and forth to break the rust loose and viola....she takes grease now. This is a lot of fun. I don't have to be quite as delicate as when working on my motorcycles and cars, and to me, a lot of extra grease flying around just adds to the ambience.
