In the past, if I puckered my mouth right(as my Daddy used to say), I could get grease through the zerk into the joint but the last couple times I greased my 4x4 I couldn't. I am using a handgun and tried a needle nose but still could not get a straight enough purchase I guess. Wondered if any of you grease your truck with a handgun and get it done completely. Thanks for the help. Dale
