Does the 5th Airborne 5th Wheel King Pin Need to Be Lubricated Internally

The squeaking you're getting on your 5th Airborne Premium 5th Wheel King Pin # 5AB-E1621-610 is fairly normal and the unit normally doesn't require any internal parts to be greased; the only thing that needs to be greased is the skid plate that the kingpin is attached to, which you can use a standard lube plate like the Lube Plate for Reese 5th Wheel Trailer Hitches - 10" Diameter # RP83002.

If you want to pull the pivoting pin at the front of the pinbox and lubricate that you'll just want to use a spray white Lithium grease. In order to do this, you'll want to check out the attached diagram that shows how the pivot pin is assembled; you will need something like a jack stand to support the skid plate while you do this repair. The bolt should be torqued to 110-ft/lbs when you put everything back together.
