Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure tires are inflated to the correct pressure.

2. Inspect and Adjust Suspension Components

Tools Required: Socket set, torque wrench, alignment tool
Sub-steps:
1. Inspect control arms, bushings, and struts for wear or damage; replace any faulty components.
2. Tighten any loose bolts to manufacturer torque specifications (refer to repair manual for specific values).
3. Adjust camber and toe angles using the alignment tool according to manufacturer specifications.
  - Camber should be set to approximately -0.5° to -1.5° (check model specifics).
  - Toe should be set to 0.0° to 0.1° (check model specifics).

3. Perform Wheel Alignment

Tools Required: Alignment rack or alignment tool
Sub-steps:
1. Place the vehicle on the alignment rack and follow the manufacturer guidelines for setting up the alignment equipment.
2. Adjust the front and rear alignment angles based on readings from the alignment tool.
3. Ensure the steering wheel is centered and make necessary adjustments to the tie rods if needed.
4. After adjustments, re-check alignment angles to confirm they are within specifications.

4. Test Drive and Final Check

Sub-steps:
1. Test drive the vehicle to ensure it tracks straight and the steering wheel is centered.
2. Re-check tire pressures and inspect for any unusual noises or handling issues after the test drive.
