    Just because it may not be questioned doesn't make it a good idea to exceed it.

    Your steer axle is the weakest link in the chain. Treat it gently, because lives depend on it.

    grumpy, what truck are you driving?

    i looked at my 5th wheel. we've got the exact same problem as far as sliding back. except i've got one notch to go.

    my frame setup looks just like yours.

    mine is positioned right above the 2 front bolts on that big bracket mounted to the frame that holds the front of the rear suspension spring.

    yours is one notch behind those 2 bolts.

    i'm wondering, like one post mentioned, if maybe your leveling valve isn't working properly. since you say the problem just started. if i remember right in an earlier post of yours.

    find yourself a cheap measuring tape. and measure each trailer load. from the side of the trailer to the ground. right down the middle of your drives.

    see if your getting a different height each time you load.

    and like another post mentioned, if you have a short scale somewhere. measure each drive axle seperately to see if you have a weight variance between drive axles.

    my steers max out at 12,400 with full tanks. with yours being one notch behind mine. you shouldn't be maxing above 12,100 with full tanks. gave or take a few pounds.

    I'm guessing you run the big tires up front? I know on carhaulers, they will come out in some states and read the sidewall. But our steers don't look like they're significantly different from a normal line-haul steer, whereas those big floats y'all run, they all know they can handle the weight.

    Generally the center of the keyhole the pin slides into should be just a little forward of the center between the drives, like maybe 1 to 2 inches. IMHO

    Ok, I finally got one to upload.. I was going to upload another but its at 1.99 MB so it wont upload (can admin help me with getting this jpeg uploaded?). It was the one that I really wanted to upload because it challenges the "Fulcrum" theory that some suggested I try by putting more weight on the drives from the tandems to weigh down the rear of the tractor to raise the steers. The weights on the ticket that wont upload is:
    Steers: 12,780
    Drives: 27,540
    Tandem: 24,960
    Gross: 65,280
    View attachment 71070

    I talked with Ryder yesterday & they dont have a clue. The best theory that I agree with, that a couple of people here suggested, is that the air leveling/adjustment valve sometimes works & sometimes doesn't. Sometimes its just crazy all over the place & either sends too much air to the system or not enough.. therefore, puts too much or too little weight on the steers. But no one seems to have a real answer.

    One rating is a single tire application which normally is the higher rating (steers) the other is a dual tire application (drives)

    Finally got another one to up load. This just makes NO sense.....

    I talked to the guys at Ryder when I took it in for a couple other things & they are clueless to. I talked with my supervisor today & we decided that we will try moving the 5th wheel forward ... despite logic... to see if that maybe whats causing, the other guess, that the air suspension is not performing right. Our hope is that since the 5th wheel is already all the way back, that's what has the air suspension shifting the weight all over the place. We are hoping by moving it to the center of the plate will cause the air to shift the weight as its supposed to. We will try that for a couple of days since I am running all local tomorrow & just across the Arkansas line where there are no scales, Friday.
