    Same problem here. Already done the same repairs. Can't wait to sell it and get a Mack again.

    You mentioned cab mounts. What about torque rods on cab and axles?

    Before you go to the trouble and expense of that.
    I’d put a coat of grease on the bump stops and see if it’s bottoming out and put a gauge inline with the air bags to confirm psi.

    Thanks for trying to help I have put grease on the bunk rubber stops but not the chassis suspension I have a load gauge on dash and seams to stay right where it needs to and I will dump the air driving down the road and u can definitely tell the difference from when there full of empty in the ride

    Only thing I will say that I found is that the radiator seams to jiggle around by hand if I really shake it by hand I’m wondering if going down the road it is going nuts and I’m felling it in the cab and frame. It is only about 6 months old with new bushings and bolts are tight

    Either way that is bad I would think.....the top and bottom tanks will crack at the welds.

    At least mine would I am not sure if you have the same setup though.
