Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery if working on electrical components.

2. Tire Pressure Check

Use a tire pressure gauge to check all tires.
Adjust tire pressures to the manufacturer’s specifications found in the owner’s manual.

3. Suspension Inspection

Lift the front of the vehicle using a jack and secure it with jack stands.
Inspect control arms, ball joints, and tie rods for wear or damage.
Replace any damaged components with new parts as needed.

4. Alignment Adjustment

Use an alignment machine to measure the camber, caster, and toe angles.
Adjust the toe angle to meet manufacturer specifications:
- Use a wrench to adjust the tie rod lengths until the toe is within specifications.
- Torque the tie rod end bolts to the manufacturer-recommended settings.

5. Tire Rotation or Replacement

Rotate the tires to ensure even wear if they are in good condition.
If tires show significant uneven wear, replace them with new tires.
