Freightliner AirLiner Component Inspection and Operation Check
sd mm 32.01.005
- Chock the front tires. Raise the rear of the vehicle so the tires just clear the ground and the suspension is fully extended. Place safety stands under the vehicle frame.
- Squeeze all air springs to check for complete deflation.
- Inspect the air spring piston for cracks, chips, and broken areas. Check the air bag for rips, tears, and holes. Verify that the air spring assembly does not leak.
- Check the axle connection welds (beam seat to equalizing beam) and axle adapter to axle for cracks. If welds are cracked, grind them out and reweld the parts observing the welding precautions given in of the 108SD and 114SD Workshop Manual.
- Move the axle up and down while checking for signs of looseness due to worn parts at the front pivot connections. Replace any worn parts.
- Inspect the shock absorbers for oil leaks and worn rubber bushings. Replace the shock absorbers and/or rubber bushings if wear or damage is noted.
- Inspect the stabilizer bar, if so equipped, for irregular bushing wear or cracks in the brackets. The stabilizer bar is optional on 10,000- and 15,000-pound AirLiner suspension systems.
- Remove the safety stands and lower the rear of the vehicle to the ground. Run the engine until air pressure of at least 100 psi (689 kPa) is maintained throughout the system.
- Check that all air springs are inflated.
Warning: Inspect the components and check their operation as described below. Failure to perform these inspections and checks could result in separation of worn suspension components and loss of vehicle control, possibly causing personal injury or death, or property damage.
