Neway Suspension
- Inspect the fasteners that attach the suspension brackets to the frame for proper torque. See for bolt torque specifications.
- Visually inspect each suspension bracket for any evidence of cracks and rust streaks coming out from between the frame rail and the bracket.
- Check the shock absorbers. For instructions, see Front Suspension Check, "Suspension Inspection."
- Inspect the air bags for sufficient and equal pressure. Examine the air bags for wear and cuts.
- Park the vehicle on a level surface, using a light application of the brakes. Do not apply the parking brakes. Shift the transmission into neutral, and build the secondary air pressure to at least 100 psi (690 kPa). Shut down the engine.
- Mark the location of the front and rear tires on the floor, and chock the tires on one axle only.
- Check the ride height by measuring the distance from the bottom of the frame rail to the center of the axle. The correct ride height is from 9-3/4 to 10-1/4 inches (248 to 260 mm).
Warning: Before making any inspections, always make sure that the vehicle's park brake is set and that the wheels are chocked to prevent accidental vehicle movement to prevent serious injury.
Warning: Be sure that the fasteners are torqued correctly. Fasteners that are not tight can cause separation of components or premature failure of components, loss of vehicle control and possible personal injury or property damage.
Warning: If damaged air bags are found, do not continue to use the vehicle, take the vehicle to your Western Star dealer to have the air bags replaced because the sudden loss of air bag pressure can cause loss of vehicle control resulting in serious personal injury and property damage.
