Someone told me about putting sheets of wax paper on the pins where the trunnion bars lock into the hitch instead of messing with grease, and it works. I take about a 6 inch piece and fold it in half and put on the two pins before I put the bars on the hitch. When I get where I am going I throw out the wax paper, no greasy mess to deal with.
