Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Remove all four tires using a jack and socket set.
2. Measure tread depth using a tread depth gauge; replace tires if tread is below 2/32 inch.
3. Inspect tires for uneven wear patterns, bulges, or punctures and replace if necessary.
4. Ensure that all tires are the same brand and model for uniform performance.

2. Tire Pressure Adjustment

Sub-steps:
1. Check the recommended tire pressure in the owner’s manual or on the driver’s side door jamb.
2. Use an air compressor to inflate tires to the recommended pressure.
3. Re-check pressure with a tire gauge after inflation to confirm accuracy.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle and support it with jack stands.
2. Visually inspect shock absorbers, struts, and springs for any signs of damage or leaks.
3. Replace any worn or damaged components as necessary.

4. Traction Control System Check

Sub-steps:
1. Perform a test drive under controlled conditions to assess traction control functionality.
2. If the traction control warning light is on, use an OBD-II scanner to retrieve and address any stored fault codes.
3. Repair or replace any faulty sensors related to the traction control system.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use alignment tools.
2. Adjust the alignment settings to match the manufacturer specifications.
3. Test drive after alignment to ensure proper handling.
