kingpin lube
I have a pullrite 16k hitch. The owners manual states to use wd40 on the kingpin before every trip. Should I use this or grease ?? Starting to see a little wear on the kingpin after 7yrs of wd40 us...

We went with a slip plate, it has worked fine for the past year and no worries about getting grease where I don't want it. I get enough of that as an OTR driver already.
