Solution

1. Preparation

• Tools Required: Jack and jack stands, tire pressure gauge, torque wrench, alignment tools.
• Raise the vehicle and secure it on jack stands.
• Ensure all necessary tools and replacement parts are within reach.

2. Tire Inspection and Inflation

• Sub-steps:
  • Remove wheel covers if applicable.
  • Inspect each tire for visible damage (bulges, cracks).
  • Use a tire pressure gauge to check the tire pressure; inflate to manufacturer specifications if low.
  • Rotate tires to ensure even wear, if necessary.

3. Wheel Balancing

• Sub-steps:
  • Remove the wheel from the hub.
  • Take the wheel to a tire shop for professional balancing.

4. Alignment Check

• Sub-steps:
  • Use alignment tools to measure the alignment angles.
  • Adjust toe and camber as necessary to match manufacturer specifications.
  • Test drive the vehicle to check for improvement in handling.

5. Suspension Component Inspection

• Sub-steps:
  • Visually inspect shocks, struts, and bushings for signs of wear or leaks.
  • Replace any worn components with OEM or high-quality aftermarket parts.
  • Reassemble and ensure all bolts are torqued to specifications.

6. Drivetrain Inspection
