Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Required tools: jack, jack stands, wheel chocks, torque wrench, alignment equipment.

2. Tire Pressure Check

Sub-steps:
- Use a tire pressure gauge to check the pressure in all tires.
- Inflate or deflate tires as necessary to match the manufacturer's specifications.

3. Tire Inspection

Sub-steps:
- Remove the wheel covers or hubcaps if necessary.
- Inspect the tread for uneven wear patterns (e.g., bald spots, cupping).
- Rotate tires if uneven wear is detected to promote even wear.

4. Suspension Component Inspection

Sub-steps:
- Safely lift the vehicle using a jack and secure it with jack stands.
- Visually inspect all suspension components for signs of wear or damage.
- Replace any worn or damaged parts, such as control arms or bushings.

5. Wheel Alignment Adjustment

Sub-steps:
- Set up the alignment machine according to the manufacturer's specifications.
- Adjust camber, toe, and caster angles as necessary to bring them within specification.
- Tighten all adjustment bolts to the manufacturer's recommended torque values.
