Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, alignment machine, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic steering components.

2. Tire Inspection

Check tire pressure and adjust to manufacturer specifications (usually found on the driver's door jamb).
Inspect tire tread for uneven wear patterns; replace tires if necessary.

3. Suspension and Steering Inspection

Lift the vehicle and securely support it with jack stands.
Visually inspect all suspension components for signs of damage or excessive wear.
- Sub-step: Wiggle each component by hand to check for play.
- Sub-step: Tap on bushings to check for cracking or deterioration.
Inspect tie rods and rack and pinion for any signs of wear or looseness.

4. Wheel Alignment

Tools Required: Alignment machine.
Perform a four-wheel alignment using an alignment machine.
- Sub-step: Adjust camber, caster, and toe settings to factory specifications.
- Sub-step: Ensure the steering wheel is centered during the alignment process.

5. Repair or Replace Components

Replace any worn or damaged suspension or steering components identified during the inspection.
- Sub-step: If replacing components, ensure proper torque specs are followed (refer to repair manual for exact values).
- Sub-step: Reassemble all parts and ensure everything is tightened to specifications.
