Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, wheel chocks.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Open the front trunk and locate the power steering fluid reservoir.
2. Check the fluid level and color; if it appears dark or contaminated, it will need to be replaced.
3. Using a turkey baster, remove the old fluid from the reservoir.
4. Refill with the recommended Tesla-approved power steering fluid to the proper level.

3. Inspect and Replace Suspension Components (if needed)

Sub-steps:
1. Lift the front of the vehicle and secure it with jack stands.
2. Remove the front wheels to access suspension components.
3. Inspect control arms, tie rods, and bushings for wear or damage.
4. If any components are worn, remove them using the socket set and replace with new parts, torqueing to manufacturer specifications.
5. Reinstall wheels and lower the vehicle.

4. Wheel Bearing Inspection and Replacement (if necessary)

Sub-steps:
1. After removing the wheel, grab the wheel hub and check for play; any movement indicates a worn bearing.
2. If replacement is needed, remove the brake caliper and rotor to access the wheel bearing.
3. Use a bearing puller to remove the old bearing and press in the new one.
4. Reassemble the brake components and wheel.

5. Final Assembly and Test

Sub-steps:
1. Reinstall the front wheels and lower the vehicle.
2. Torque the wheel nuts to the manufacturer's specifications.
3. Test drive the vehicle to ensure the grinding noise is resolved.
