Suspension System (G297322)

DIAGNOSIS AND TESTING

Inspection and Verification

WARNING:

Before carrying out a road test, make sure the vehicle is safe to do so. Failure to follow this instruction may result in personal injury.

Gather as much information from the driver as possible and verify the customer concern by carrying out a road test, as closely as possible reproducing the conditions under which the fault occurs.

Visually inspect for obvious signs of mechanical damage.

Visual inspection

Mechanical
Tire pressures Damaged wheels or tires Wheel bearing(s) Loose or damaged front or rear suspension components Loose, damaged or missing suspension fastener(s) Damaged or leaking air suspension components Worn or damaged suspension bushing(s) Loose, worn or damaged steering system components Damaged axle components

If an obvious cause for an observed or reported condition is found, correct the cause (if possible) before proceeding to the symptom chart.

Symptom chart

Symptom	Possible causes	Action
Crabbing	Incorrect rear thrust angle Front or rear suspension components	Check the rear alignment. REFER to: Four-Wheel Alignment (204-00 Suspension System - General Information, General Procedures). Check the front and rear suspension for signs of damage or wear.
Drift/Pull/Wander	Tire pressures Uneven tire wear Damaged steering components Wheel alignment Brake drag Unevenly loaded or overloaded vehicle	Check and adjust the tire pressures (see visual inspection). Check for uneven tire wear, investigate the cause and rectify as necessary. Check the steering for wear/damage. Check and adjust the wheel alignment as necessary. Check for binding brakes, rectify as necessary. Advise the driver of the load issues.
Front bottoming or riding low	Damaged suspension components Air spring fault	Check the suspension components for damage. Check the dynamic suspension. REFER to: Vehicle Dynamic Suspension (204-05 Vehicle Dynamic Suspension, Diagnosis and Testing).
Uneven tire wear	Incorrect tire pressure (rapid center rib or inner and outer edge wear) Incorrect front or rear toe (rapid inner or outer edge wear) Incorrect camber (rapid inner or outer edge wear) Tires out of balance (tires cupped or dished)	Check and adjust the tire pressures (see visual inspection). Check and adjust the wheel alignment as necessary. REFER to: Four-Wheel Alignment (204-00 Suspension System - General Information, General Procedures). Balance the wheels and tires as necessary.
Harsh ride	Damaged suspension components Air spring fault	Check the suspension components for damage. Check the dynamic suspension. REFER to: Vehicle Dynamic Suspension (204-05 Vehicle Dynamic Suspension, Diagnosis and Testing).
Shimmy or wheel tramp	Wheels/tires Loose wheel nut(s) Loose front suspension fasteners Front wheel bearing(s) fault Worn or damaged suspension component bushing Loose, worn or damaged ball joint(s) Loose, worn or damaged steering components Front wheel alignment	Check the wheels and tires for condition and balance. Check and tighten the wheel nuts and suspension fasteners to specification. Check the front wheel bearings, suspension bushings, ball joints and steering components for wear or damage. Check and adjust the wheel alignment as necessary. REFER to: Four-Wheel Alignment (204-00 Suspension System - General Information, General Procedures).
Poor returnability of the steering (self-centering)	Steering column Ball joints Steering components	Check the steering column universal joints, etc. Check the ball joints and other steering components.
Sway or roll	Loose front or rear stabilizer bar Worn lower suspension arm stabilizer bar insulators Air spring fault	Check the stabilizer bar security and condition. Rectify as necessary. Check the function of the active stabilization system (where fitted). REFER to: Ride and Handling Optimization (204-06 Ride and Handling Optimization, Diagnosis and Testing). Check the air springs. REFER to: Vehicle Dynamic Suspension (204-05 Vehicle Dynamic Suspension, Diagnosis and Testing).
Vehicle leans to one side	Front or rear suspension components Air spring fault	Check the front and rear suspension. Check the air springs. REFER to: Vehicle Dynamic Suspension (204-05 Vehicle Dynamic Suspension, Diagnosis and Testing).
