My 2011 International prostar is having leveling issues. It jumps at random and especially when I am parked. I replaced the valve and still having the issues. It is to the point to where it is damaging my lower cab at the rear. The airbags dont have leaks. Can someone please help ???

To make really long storey short. I had kinda the same issue and the only short term cure was to raise the susppension all the way up while I was sleeping.
But my lifting is no where near as extreme as yours. -
How do you mean it jumps?
You mean like a lowrider the cars with the Hydraulics that bounce up and down? -

If you have the correct leveling valve and correct ride height position when you put the new one in then it is probably the shocks
Browntyreese Thanks this. -
The symptom looks like both front airbags on the front suspension has bad valves on the air supply. There was a recall on that splitter type valve many years ago for the IH Prostar class 8 hd truck for a defect.
The suspension has no shock absorbers it uses air bags to lift and stabilize the tractor, the fault is caused by a loss in air pressure.Last edited: Sep 28, 2020
