Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands if necessary.

2. Tire Inspection and Replacement

Remove the wheel covers or lug nut covers if applicable.
Use a lug wrench to loosen and remove the lug nuts, then take off the tire.
Inspect the tire tread for uneven wear, cracks, or punctures.
If tires are worn or damaged, replace them with new tires of the same specifications.
Reinstall the tire and torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs for Toyota).

3. Alignment and Suspension Check

Inspect suspension components including struts, shocks, and control arms for signs of wear or damage.
If misalignment is suspected, perform a four-wheel alignment using an alignment machine.
Adjust the alignment to the manufacturer’s specifications.

4. Brake Inspection and Repair

Inspect brake pads and rotors for wear; replace if they are worn below the minimum thickness.
Ensure that brake calipers are functioning properly.
Bleed the brake system if necessary to remove any air in the lines.

5. Traction Control System Check

Using an OBD-II scanner, check for any stored trouble codes related to the traction control system.
Reset the codes and perform a test drive to ensure the system operates correctly.
If issues persist, further diagnostics may be required to check the wheel speed sensors and traction control module.
