Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the reservoir cap and check the fluid level.
If low, top off with the recommended fluid type (refer to the owner’s manual).
If the fluid is dirty or contaminated, drain and replace with new fluid.

3. Inspect Steering Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the tie rod ends and ball joints for wear or damage.
If any components are damaged, replace them before proceeding.

4. Check Wheel Bearings

Shake the front wheels to check for any play.
If any looseness or grinding is felt, the wheel bearings should be replaced.
Remove the wheel, then remove the brake caliper and rotor to access the wheel bearing.
Replace the wheel bearing and reassemble components.

5. Reassemble and Test

Reattach the brake rotor and caliper securely.
Reinstall the wheel and tighten lug nuts to the manufacturer's specifications (typically 75-100 ft-lbs).
Lower the vehicle and reconnect the battery.
