Can worn kingpins be refurbished?

My kingpin is showing a lot of wear after 13 years of long trips. I believe that big truck semi-trailer kingpins can be refurbished, but what about RV fifth-wheels? Do you really have to replace the entire kingpin assembly, which can cost upwards of a $thousand?
  • I had mine welded. It had a groove worn in it about 1/4" deep. Works pretty well.
  • Did you keep it greased?

    Not sure how you wear one out, if cleaned and greased regularly?
  • Take your box and a new pin to ANY welding shop. It's nothing special. Craig

    Why not check local RV dealers for take-off's from customers who upgraded to air ride of premium pin boxes.

    If unsure where or how to locate a semi trailer repair shop, contact a local Ryder or Penske semi rental shop for help in locating one.
  • Why not consider replacing the pinbox. It's not that difficult and not that expensive.

    Here's an example

  • I don't see why not, one would need to find a good welding shop that knows how to replace a king pin do it.
