I tried to grease the front suspension zerk fittings on my SPF and had a little trouble. A couple of the fittings worked as expected. When I pumped grease, it seemed to go into the fitting. On several other fittings, when holding the gun as tight as I could on the fitting, the fresh grease just oozed out the side of the connection between the gun and the fitting. No grease seemed to go into the area needed. What is up with that? (I've always called the grease fittings zerk fittings. Is that what they are really called now days?)
