Solution

1. Preparation

Gather the necessary tools and ensure the vehicle is on a flat, level surface.
Tools required: Alignment gauge, tape measure, jack and jack stands, wheel chocks.

2. Inspect and Adjust Toe Alignment

Sub-steps:
1. Use the alignment gauge to measure the distance between the front and rear edges of the front tires.
2. Compare the measurements to the manufacturer's specifications for toe alignment.
3. If adjustments are needed, loosen the tie rod lock nuts.
4. Turn the tie rods to adjust the toe angle until the measurements are within specifications.
5. Tighten the tie rod lock nuts to the specified torque (typically around 30 Nm).

3. Check and Adjust Camber Angle

Sub-steps:
1. Use the alignment gauge to measure the camber angle of each front wheel.
2. If the camber angle is not within specifications, adjust by loosening the upper control arm bolts.
3. Position the control arm to achieve the correct camber angle.
4. Retighten the control arm bolts to the specified torque (usually around 80 Nm).

4. Final Verification

Sub-steps:
1. Re-measure the toe and camber settings to ensure they are within specifications after adjustments.
2. Perform a test drive to confirm that the vehicle tracks straight and the steering wheel is centered.
