1. Preparation

Tools Required: Jack and jack stands, torque wrench, alignment tool, socket set, tire pressure gauge, and possibly a steering rack puller.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the 12V battery to prevent any electrical issues.

2. Inspect and Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check the current pressure of all four tires.
2. Inflate or deflate the tires to match the recommended pressure found in the owner’s manual or on the driver's door jamb.
3. Recheck tire pressure after adjustments.

3. Check and Adjust Wheel Alignment

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the alignment components if necessary.
3. Use an alignment tool to measure the camber, caster, and toe settings.
4. Adjust the tie rods and control arms as necessary to achieve proper alignment specifications (consult the service manual for specific torque values).
5. Reinstall the wheels and lower the vehicle.

4. Inspect Steering and Suspension Components

Sub-steps:
1. Visually inspect the steering rack, tie rods, and control arms for any signs of wear or damage.
2. Check the condition of the bushings and bearings in the suspension components.
3. Replace any worn or damaged components found during inspection.

5. Final Assembly and Test Drive

Sub-steps:
1. Reconnect the battery and ensure all tools are removed from the vehicle.
