Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the car is parked on a level surface and the ignition is off.
Disconnect the 12V battery to prevent electrical shorts during repairs.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick indicator.
If low, add the recommended power steering fluid type (e.g., Tesla-approved fluid).
Recheck for leaks around the reservoir and hoses.

3. Check Power Steering Motor

Reconnect the battery.
Turn the ignition to the "on" position without starting the vehicle.
Listen for the power steering motor operation; it should be quiet and smooth.
If the motor is noisy, it may need replacement.

4. Inspect Suspension Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, tie rods, and bushings for wear or damage.
Replace any worn components with OEM parts as necessary.

5. Examine Wheel Bearings

Spin the front wheels while the vehicle is lifted.
Listen for any grinding or roughness indicating bad wheel bearings.
If noise is present, replace the wheel bearings following manufacturer guidelines.
