- Chock the front tires. Raise the rear of the vehicle so that the tires just clear the ground and so that the suspension is fully extended. Place safety stands under the vehicle frame.
- Squeeze all air springs to check for complete deflation. If any air springs remain partially or fully inflated, see General Information, Freightliner Front Suspension of the Shuttle Bus Chassis Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
- Inspect each air spring for wear at its connection to the pedestal. Replace any worn air springs; for instructions, see General Information, Freightliner Front Suspension of the Shuttle Bus Chassis Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
- 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.
- 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 by following the procedures in General Information, Freightliner Front Suspension of the Shuttle Bus Chassis Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
- 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. For instructions, see General Information, Freightliner Front Suspension of the Shuttle Bus Chassis Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
- 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. If the air springs do not inflate, see General Information, Freightliner Front Suspension of the Shuttle Bus Chassis Workshop Manual for possible causes and corrections, or take the vehicle to an authorized Freightliner dealer.
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 and property damage.
