Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Refill Power Steering Fluid

Tools Required: Funnel, rags
Locate the power steering reservoir and inspect the fluid level.
If low, clean the cap and remove it, then add the appropriate type of power steering fluid (refer to the owner's manual for specifications).
Reinstall the cap and reconnect the battery.

3. Check Steering Components

Tools Required: Socket set, jack stands
Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the tie rods, control arms, and ball joints for wear or damage.
If any components are worn, replace them with OEM parts.

4. Inspect and Replace Differential Fluid (if applicable)

Tools Required: Drain pan, socket set, torque wrench
Locate the differential drain plug and remove it to drain the fluid.
Inspect the fluid for metal shavings or discoloration.
Clean the drain plug and reinstall it.
Fill the differential with the specified fluid type using a pump until it reaches the fill level.

5. Test Drive the Vehicle

After repairs, take the vehicle for a test drive to ensure the noise has been eliminated.
