Disconnect the battery if necessary.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; refill with the manufacturer-recommended fluid if low.
Inspect the fluid for contamination; if dirty, consider flushing the system.

3. Inspect CV Joints and Boots

Safely lift the front of the vehicle using jack stands.
Remove the front wheels for better access.
Carefully inspect the CV joints and boots for cracks or leaks.
If damaged, replace the affected CV joint or boot.

4. Examine Suspension Components

Check the control arms, ball joints, and tie rod ends for any signs of wear or damage.
Replace any worn or damaged components.
Ensure all bolts are torqued to the manufacturer's specifications.

5. Check Wheel Bearings

With the vehicle still lifted, grab the wheel at the 12 and 6 o'clock positions and shake it.
If there's play, the wheel bearing may need replacement.
If necessary, remove the hub assembly and replace the bearings, ensuring to properly torque all bolts.
