Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, tread depth gauge, jack, jack stands, lug wrench.
Check each tire's pressure; inflate to manufacturer specifications if needed.
Measure tread depth; replace tires if tread is below 2/32 of an inch.
Look for any visible damage such as bulges or cuts in the tire sidewall.
If replacement is necessary, lift the vehicle using the jack, remove the lug nuts with the lug wrench, and replace the tire. Torque the lug nuts to the manufacturer's specifications.

3. Suspension and Drivetrain Inspection

Tools Required: Wrench set, socket set, jack, jack stands.
Raise the vehicle and securely support it on jack stands.
Inspect all suspension components for play or damage, including bushings, control arms, and struts.
Check the driveshaft and differential for any abnormalities; replace any worn components as needed.

4. Traction Control System Check

Tools Required: OBD-II scanner, multimeter.
Use the OBD-II scanner to read any error codes related to the traction control system.
If codes indicate a sensor issue, test the sensors using a multimeter to verify their operation.
Replace any faulty sensors and clear the error codes.

5. Wheel Alignment

Tools Required: Alignment tool or access to a professional alignment shop.
After ensuring all components are in good condition, check wheel alignment using an alignment tool.
Adjust alignment according to manufacturer specifications; if alignment is out of spec, visit a professional shop for precise adjustments.
