I'm pulling a 10k enclosed car carrier. The dealer that sold me the trailer said that I didn't need any lube for the ball as the paint inside the coupler on the trailer would do the job. It did for the first two pulls. Now the hitch groans when ever the truck moves relative to the trailer and there is some galling on the ball. What lube do you folks use for this application? I'm thinking of using some plain old extreme pressure moly-graph multi purpose grease; but only because I have some. Any one know what is recommended here?
Thanks in advance,
PK
