5ht Wheel hitch grease - the definitive

Searched the 5th threads for "hitch,grease" and came back with some hits, but nothing that gives me a definitive.

What's your opinion on greasing the 5th wheel, what type of grease, how often to clean the old and re-grease. Just the pin or the plates too? What about the nylon plates that the king pin goes through, are those worth the 12 bucks and should you grease the plates also?
  • Took delivery today of a B&W graphite impregated plastic disk.
  • I have a 4 way articulating head///pivots fore/aft and side/side

    Once a year:
    I pull side pins that allow fore/aft and clean/grease them...thin film of moly bearing grease
    I pull large center pin that allows side/side and clean/grease it...heavier film of moly bearing grease

    Twice a year:
    I spray a quick shot of white lithium grease on jaw pivot points

    As needed.....thin film of moly bearing grease on King pin where Jaws make contact

    All year long..........plastic/nylon/teflon plate (whatever it is made of)

    No grease on head surface/plates etc (then none on me or my clothes)
  • I have the B&W hitch and grease it where required, which translates to the zerks, the saddles, and the hitch jaws. Basically anywhere there is metal to metal contact, or the possibility of wear. I use the nylon/teflon disc on the fifth wheel pin.
  • Nylon plate and a very small amount of grease on the pin.
  • All you need is the nylon plate on the pin box. I lightly grease the pin in the recess area, and also a thin coat on the jaws. I use teflon trailer hitch lube on pin and jaws.

  • I don't use grease either but I use an Andersen and the manual explicitly says not to use it.
  • I use the nylon plates exclusively. Have never used grease on the hitch other than the mechanical parts.
