Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, wheel alignment tool, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Pressure Adjustment

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

3. Steering and Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect tie rods for wear or play by attempting to move them laterally.
3. Check ball joints and control arm bushings for signs of excessive wear.
4. Replace any worn components with OEM parts.

4. Wheel Alignment

Sub-steps:
1. Set up the wheel alignment tool according to the manufacturer's instructions.
2. Adjust the alignment to meet the manufacturer’s specifications for camber, caster, and toe.
3. Tighten all adjustment bolts to the specified torque values.

5. Power Steering Inspection

Sub-steps:
1. Check the power steering fluid level; top off if low using the recommended fluid type.
2. Inspect power steering hoses and connections for leaks or damage.
3. Replace any faulty components (e.g., power steering pump, steering rack) as needed.
