Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the hubcaps or wheel covers if applicable.
2. Loosen the lug nuts on each tire using a socket set.
3. Lift the vehicle using a jack and secure with jack stands.
4. Fully remove the lug nuts and take off the tires.
5. Inspect tires for uneven wear, damage, and tread depth; replace if necessary.
6. Reinstall tires, tighten lug nuts to the manufacturer’s specifications (typically 76 ft-lbs).
7. Lower the vehicle and recheck tire pressure, adjusting to the recommended PSI.

3. Traction Control System Check

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any existing codes.
3. Start the vehicle and monitor for warning lights on the dashboard.
4. If a code is present, refer to the specific code for further diagnosis (e.g., faulty wheel speed sensor).
5. If necessary, replace the wheel speed sensors or the traction control module as indicated.

4. Drivetrain Inspection

Sub-steps:
1. Check CV joints and boots for cracks or leaks.
2. Inspect the differential fluid level; replace if low or contaminated.
3. If any components are worn, replace with OEM parts following manufacturer torque specifications.

5. Alignment Check

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment to ensure proper handling and traction.
