    Can anyone tell me is there any way to tighten up a 5th wheel. The kin pin slides back and forward while hooked to the truck. I guess maybe an inch or two play.

    DOT says 1/2" max play.
    Most have an adjustment nut you can tighten but at some point, especially with age
    you need to have it rebuilt.

    Yes it does have an adjustment. But chances are you are pulling an older trailer and the pin is worn too.

    I'm pulling a 96 tanker so yes it is pretty old. Every now and then I'll switch trls. and pull a newer one. And it does the same thing although not as bad. Is the adjusting something I can do myself or will I need a mechanic to do it.

    Depends on the make and model, but most have a bolt and nut coming out of the front of the base plate. I was in the same boat about two years ago, it got annoying as hell, so I had it rebuilt, to be honest I think you are just as well off to just replace the whole base plate.

    I found a big truck wrecking yard not far from me that sells a complete late model 5th assm, for 200.00

    Just my take on it.

    I have a Volvo 780. It doesn't have that bolt on the front of it. We do have a truck wreck yard here. I think I'll check them out.

    If you go that route just make sure it's of a late model (within a year or two) of being new. JMHO

    My Holland has the 13/16" adj nut inside the throat and you don't want to get it too tight!

    That must be fun yanking a tanker with all that slop!

    LOL, that's what I was thinking, you would feel like one of those shake weights.
