Solution

1. Preparation

• Gather tools including a jack, jack stands, tire pressure gauge, and an OBD-II scanner.
• Ensure vehicle is on a level surface and securely lifted.

2. Tire Inspection

• Sub-steps:
  • Check each tire for proper inflation (recommended pressure found in the owner’s manual).
  • Inspect tread depth using a tread depth gauge; replace if below 2/32 inches.
  • Look for bulges, cuts, or any visible damage; replace damaged tires.

3. Wheel Alignment

• Sub-steps:
  • Using alignment tools, check all four wheels for proper alignment settings (refer to manufacturer specifications).
  • Adjust toe, camber, and caster angles as needed to bring into specification.
  • Test drive the vehicle to confirm stability.

4. Suspension Inspection

• Sub-steps:
  • Visually inspect struts and shocks for leaks or physical damage.
  • Check control arm bushings for wear; replace if cracked or torn.
  • Shake the wheels to check for play; replace any worn components.

5. Steering System Check

• Sub-steps:
  • Examine the steering rack and linkage for any signs of wear or play.
  • Inspect the power steering fluid level and condition; top off or replace if contaminated.
  • Test drive the vehicle to evaluate steering responsiveness.
