Disconnect the battery if working on electronic steering components.

2. Tire Inspection and Adjustment

Check and adjust tire pressures to manufacturer specifications.
Inspect each tire for signs of damage or uneven wear; replace any damaged tires.
Rotate tires if uneven wear is noted to promote even wear patterns.

3. Suspension Component Replacement

Tools Required: Wrench set, socket set, torque wrench.
If any suspension components (e.g., struts, shocks, control arms) are found damaged, replace them.
- Loosen the bolts of the affected component.
- Remove the component from its mounting points.
- Install the new component and torque to manufacturer specifications.
