Hey guys. I have a 2004 VNM. This truck was cut from 182" down to 158". The leveling valve has the chassis way to high and raises the rear axle off of the ground when driving up or down hill. So I cut the rod so that the truck levels at a lower height. Truck rides perfect now with no issues. EXCEPT. The leveling valve only lasts three months before it starts leaking and needs replacing. Can anyone help with this issue?
