Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake and chock the rear wheels.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure and inflate to the recommended PSI.
2. Use a tread depth gauge to measure tread depth; replace tires if tread is below 2/32 inches.
3. If uneven wear is detected, rotate or replace tires as necessary.

3. Wheel Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Adjust camber, caster, and toe settings to manufacturer specifications.
3. Tighten all components to the specified torque settings post-adjustment.

4. Suspension Component Replacement

Sub-steps:
1. Lift the vehicle and remove the wheel to access suspension components.
2. Inspect and replace any worn or damaged shocks, struts, or control arms.
  - Use a torque wrench to tighten bolts to manufacturer specifications.
3. Reinstall the wheel and lower the vehicle.

5. Steering System Inspection and Repair

Sub-steps:
1. Inspect tie rods and the rack and pinion for any signs of play or damage.
2. Replace any damaged steering components.
3. Recheck alignment after any steering component replacement.
