    Hi all,

    I'm not very mechanically inclined and during a pre trip I found this little lever bar sitting on the drive shift. So naturally I pulled it up out of curiosity and it let out a loud hiss of air from I don't know where. It seems bumps from the truck could cause it to discharge. Idk just looks weird to me. Any idea what it is? On a 2015 international prostar. Thanks !

    Sounds like a leveling valve but levelling valves don't connect to the driveshaft.

    Definitely a levelling valve. Linkage is definitely broken. Guessing its under the cab/sleeper?

    Yeah under around where the sleeper would be, couple feet in front of my catwalk. Something that needs fix asap you think? Or not really hurting anything right now/ fix when funds allow?

    Needs to get fixed ASAP.
    The linkage to the air leveling valve is broken and rubbing on the driveshaft.
    How long is this been this way?
    Looks like it’s been a while by the mark on the shaft?

    Fix it NOW... it could cause your sleeper air bags to go out. Sleeper air bag/Struts are $300 (new style) or $750 (old style) each....!!

    Hinge the piece 90 degrees,pointing straight up from the bolt head, near where it ends should be a rubber boot or something looking broken, take a pic of that and post

    Might cost nothing try to find other end that looks like the piece still attached. Could be a loose clamp let it unhook . PS this is why you’re ride is rough
