Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check the fluid level; if low, add the recommended power steering fluid type.
If leaks are found, replace the power steering lines or reservoir as needed.

Remove the front wheels to access the steering components.
Visually inspect the tie rod ends and steering rack for wear or damage. Replace any worn components.

4. Check Wheel Bearings

With the wheels off, grasp each wheel and check for play by rocking it side to side.
If there is excessive play or grinding noise, remove the hub assembly and replace the wheel bearings.

5. Inspect CV Joints

Check the CV joint boots for any tears or leaks. Replace torn boots and repack the joints if necessary.
