Remove the wheel covers or wheel to access the sensors.
Disconnect the wiring harness from each wheel speed sensor.
Clean the sensor mounting area and connector terminals.
Reattach the harness securely and reassemble the wheel.

3. Check Tire Pressure and Condition

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to the manufacturer's recommended levels.
Inspect the tread depth and sidewalls for any signs of damage or excessive wear.

4. Align the Vehicle

Use a professional alignment tool to measure the alignment angles.
Adjust the camber, caster, and toe as necessary to bring them within the manufacturer's specifications.
Test drive the vehicle to ensure the alignment adjustments are effective.
