Preliminary Alignment Inspection for Saturn L300/LW300 2000

Road Test Vehicle

Road test vehicle. This gives clues to the condition of components in steering and suspension systems.

Tires

Inspect tires for wear and proper inflation pressure.

    • Both tires on axle have about the same wear.
    • The wear pattern across the tire
        This is very helpful in diagnosing alignment and steering/suspension problems.

Front Suspension

Inspect the steering/suspension systems. Alignment angles cannot be set accurately if steering or suspension systems are worn or damaged.

    • Inspect the suspension/steering components for wear or damage.
    • Inspect to see if the frame is bent.

    • Inspect the steering gear for wear or damage.
    • Inspect the inner and outer tie rod ends for wear or damage.
    • Inspect the wheel bearing for looseness.
    • Inspect the bumper height. Height must be within specifications before setting alignment.
    • Inspect the strut assemblies for oil leaks, looseness, wear, binding or dents.

Rear Suspension

    • Inspect the components for wear/damage.
    • Inspect the rear axle control arm.
      • Are the bushings worn?
      • Are the arms bent?
    • Check rear suspension support.
      • Are the bushings worn?
      • Are the links bent?
    • Inspect the bumper height. Height must be correct before setting alignment. If not, are carrier assemblies leaking, worn, binding, or bent?
    • Inspect the rear stabilizer bar.
      • Are the bushings worn or missing?
      • Is the bar bent?
