1. If any steering or suspension components were found to be damaged during inspection (e.g., tie rods, ball joints), proceed to replace them.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the affected component using the correct socket size and torque specifications.
4. Install the new component, ensuring all fasteners are torqued to the manufacturer’s specifications.
5. Reassemble any other components that were removed for access.

4. Wheel Alignment

Sub-steps:
