A. When inspecting or setting ride height on a lightly loaded vehicle with a dual height control valve, it is necessary to have a load on the vehicle. Loading the vehicle to its normal operating condition, such as a tractor with a loaded trailer, increases ride height setting accuracy. HINT: It’s important that the height control valve be cycled completely before and after any ride height adjustments. Cycling of the height control valve will help make the adjustment more accurate. A vehicle equipped with dual height control valves must measure the ride height at each height control valve location. All ride heights are measured on the axle attached to the height control valve(s). Ride height is measured from the bottom of the frame to the axle centerline.
