    Hi y’all. I have followed this form for awhile picking up the do’s and do nots of this industry. Obviously this is my first post. I have some slop in my fifth wheel. I am on my 34 right now and would like to know the proper way to adjust the fifth wheel. I have a 2013 Pete 389. The wagon is a 2019 so I have a hard believing it’s in the kingpin. Help would be much appreciated and I have pictures of the bolt that I believe is used for the adjustment.

    You don’t have very much adjustment left. Turn the nut counterclockwise to take up the slack. Inch and eighth socket. Best done with a tool but can be faked turn adjust nut rehook check release repeat as needed

    Okay, thank you. I guess since there isn’t much adjustment left, I will be looking for a new fifth wheel plate here shortly

    I just put a new plate on mine last week. Figured that by the time you bought a rebuild kit for $400 and time involved it wasn't worth it to rebuild my old one vs 30 minutes to swap the plate out.

    That’s what I have read on here in some older forums. They said it’s just as easy to just buy a new one instead of rebuilding it. I didn’t know how much more adjustment I had left. I pull the same trailer so I’m wondering if a greaseless fifth wheel would be the way to go

    I’m in the same situation. As stated, while eased up on trailer, loosen bolt,snug it up, not too tight. Need to be able to turn washer be hand. Not textbook, but it works. Don’t forget new bushings

    How do I know my 5th wheel needs replacement? They had me do a tug test (no dropped trailer) on a level-1 DOT inspection. The officer said he was checking for some slack. I’m starting to think the test should have been done with the lading gear down.

    I got a Fontaine with the Side adjustment (Wedge stop rod) They say its a "No Slack" But i have to adjust it every once in a while.
    You want about a 1/8 to 1/4 of play between wedge and pin- to be adjusted correctly
    On your Tug Test- What was the result?? I know if its more than 1./2 inch,It can be a failed test

    It passed, but I don’t think the officer knew what he was doing. Hahaha.

    Same here, When He asked me to ease up on it to check slack, My first thought was, Oh no!! Ive Never had to do that before, thought I was OOS. Luckily it didn’t move, probably a little dry, Lol. But it’s nowhere near 1/2” play, I keep just enough grease on it, meanwhile to protect Trailer pin and plate.Drive it easy, hardly notice it.Next time may not be so lucky.
