Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire tread depth using a tread depth gauge; replace tires if tread is below 2/32 inch.
2. Inspect tire sidewalls for bulges, cracks, or foreign objects.
3. Inflate tires to the manufacturer's recommended PSI (found on the driver's door jamb).
4. Replace tires if necessary, ensuring to match the size and type recommended for the vehicle.
Tools Required:
- Tire pressure gauge
- Tire changing tools (jack, lug wrench)

3. Traction Control System Check

Sub-steps:
1. Connect an OBD-II scanner to the vehicle's diagnostic port.
2. Scan for error codes related to the traction control system and record any findings.
3. Clear codes and perform a test drive to see if the issue persists. If codes reappear, investigate further based on code descriptions.
Tools Required:
- OBD-II scanner

4. Suspension Component Inspection

Sub-steps:
1. Visually inspect struts, shocks, and bushings for signs of wear or damage.
2. Perform a bounce test on each corner of the vehicle to check for proper damping.
3. Replace any worn or damaged suspension components as needed.
Tools Required:
- Socket set
- Wrench set

5. Wheel Alignment

Sub-steps:
