Solution

1. Tire Inspection

Sub-steps:
- Remove any hubcaps or wheel covers to access the tires.
- Check each tire for tread depth using a tread depth gauge; replace tires with insufficient tread.
- Inspect for any visible damage, such as cuts or bulges.
- Ensure all tires are inflated to the manufacturer's recommended pressure.

2. Traction Control System Check

Sub-steps:
- Use an OBD-II scanner to retrieve any stored codes related to the traction control system.
- Inspect the wheel speed sensors on each wheel for any signs of damage or corrosion.
- Ensure the wiring harnesses connected to the wheel speed sensors are secure and undamaged.

3. Drivetrain Assessment

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect CV joints for any signs of wear or grease leakage.
- Check the differential fluid level and condition; replace fluid if dirty or low.

4. Alignment Verification

Sub-steps:
- Take the vehicle to an alignment shop to check and adjust alignment settings.
- Ensure caster, camber, and toe are within specifications as per manufacturer guidelines.
