[MandK]

I have the B&W Companion hitch and the instructions that came with it mention greasing it and maintaining it. It’s straight forward and easy to do. There are a couple of zerk fittings on it for grease. I use the Red and Tacky bearing grease. I Also grease the jaws. I wipe the old grease off the jaws before regressing because it picks up dirt being in the bed of the truck. A little grease here is all it needs on the surfaces that wrap around the king pin.
I do run a Teflon lube plate so I don’t have to have grease all over the hitch head and the bottom of the pin box.
