Solution

1. Preparation

• Gather necessary tools and parts: tire pressure gauge, jack, jack stands, lug wrench, alignment tool, and balancing weights.
• Park the vehicle on a flat surface and turn off the engine.

2. Tire Pressure Adjustment

• Sub-steps:
  1. Remove the valve cap from each tire.
  2. Use a tire pressure gauge to check the pressure.
  3. Inflate or deflate the tires to meet the manufacturer’s specifications (usually found on the driver’s door jamb).
  4. Replace valve caps securely.

3. Wheel Balancing

• Sub-steps:
  1. Remove the wheel and tire assembly from the vehicle using a lug wrench.
  2. Mount the tire on a balancing machine and follow the manufacturer’s instructions for balancing.
  3. Add balancing weights as needed based on the machine's readings.
  4. Reinstall the wheel and tire assembly, tightening lug nuts to the manufacturer’s torque specification.

4. Wheel Alignment

• Sub-steps:
  1. Lift the vehicle using a jack and secure it with jack stands.
  2. Attach alignment equipment to the front wheels.
  3. Adjust the alignment angles (caster, camber, toe) as specified in the vehicle's service manual.
  4. Lower the vehicle and perform a test drive to ensure proper alignment.

5. Suspension Inspection and Repair

• Sub-steps:
  1. Visually inspect all suspension components for signs of wear or damage.
  2. Replace any worn parts such as control arms, tie rods, or bushings with new OEM parts.
  3. Reassemble any components that were disassembled during inspection.
