I picked some white lithium grease up at my RV dealer. You can get it at any auto parts store also. I had taken my tailgate off and had also noticed the rusting. I sanded it off and coated the pins with the grease. Finding little rust spots all over. The hinges, the bolts that attatch the wire fender brace just in front of the rear tires (back em off and have a look, its bare metal under there), the back of the front bumper (noticed a lot of rust when I took it off to move it forward). It bugs me to know somewere else I'm not aware of, rust is getting a foothold. I want this truck to last me, and I don't want a good running truck thats a rusted POS.
