Tools Required: Alignment rack and alignment tools.
Position the vehicle on the alignment rack.
Follow the manufacturer specifications to adjust camber, caster, and toe angles.
Ensure all adjustments are tightened to the specified torque values.

4. Inspect and Replace Suspension Components (if necessary)

Tools Required: Socket set, wrench set, torque wrench.
Visually inspect all suspension components for wear or damage.
If any components are found defective, they should be replaced:
- Remove the damaged part (e.g., control arms, tie rods).
