Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure and inflate to the manufacturer's specifications.
2. Inspect for tread depth using a tread depth gauge; replace tires if tread is below 2/32 inch.
3. If tires are worn unevenly, rotate them or replace as necessary.
Tools Required: Tire pressure gauge, tire iron, jack, jack stands.

3. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect suspension components for wear or damage, focusing on struts and bushings.
2. Replace any damaged components; use OEM parts for best performance.
3. Recheck the alignment after replacing components and perform a wheel alignment if necessary.
Tools Required: Wrench set, alignment tools.

4. Traction Control System Check

Sub-steps:
1. Reconnect the battery and use an OBD-II scanner to clear any stored codes.
2. Inspect the wheel speed sensors for dirt or damage; clean or replace as needed.
3. Test the traction control system function by driving in a controlled environment to ensure it engages properly.
Tools Required: OBD-II scanner, multimeter.
