Chalmers Suspension
- Inspect the fasteners that attach the suspension brackets to the frame for proper torque. See for bolt torque specifications.
- Chock the front tires to prevent the vehicle from moving. Place the transmission in neutral, and release the parking brakes before inspecting the Chalmers rear suspension.
- Power-wash the Chalmers rear suspension, or clean it with a hard-bristle brush before performing a visual inspection.
- Visually inspect the rubber bushings for cracks or other damage. Try to move the torque rod ends using your hands only, and check for any free-play. If free-play is felt, replace the torque rod end bushing. Do not use a pry bar to check for free-play. Use of a pry bar may lead to premature bushing replacement.
- Visually inspect the walking beam for cracks or other damage. If damage is found, replace the walking beam.
- Visually inspect the restrictor cans for cracks, severe corrosion, and distortion. If any of these conditions are present, or the restrictor can is missing, replace it.
- Check the shock absorbers. For instructions, see Front Suspension Check, "Suspension Inspection."
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: Replace all cracked or missing restrictor cans. Failure to do so could lead to loss of vehicle control, which could result in property damage, serious personal injury, or death.
