Solution

1. Preparation

Gather tools and parts needed for the alignment process.
Ensure the vehicle is parked on a level surface and the tires are properly inflated.
Tools Required: Wheel chocks, jack, jack stands, torque wrench.

2. Raise the Vehicle

Use the jack to lift the vehicle and place jack stands under the vehicle for safety.
Ensure the vehicle is stable before proceeding.

3. Adjust Alignment

Front Alignment:
1. Loosen the tie rod adjusting sleeves using a wrench.
2. Using an alignment tool, adjust the toe angle to the manufacturer's specifications (typically 0.06 to 0.12 degrees positive toe).
Rear Alignment:
1. If equipped with adjustable rear suspension, loosen the adjustment bolts on the rear control arms.
2. Adjust the rear toe as necessary to fall within the specifications (typically 0.10 to 0.30 degrees positive toe).

4. Tighten and Torque

After adjustments, re-tighten all fasteners to the manufacturer’s torque specifications (check the service manual for specific torque values).
Ensure all components are secure and properly aligned.

5. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Tools Required: Torque wrench.
