Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather tools and safety equipment.
Tools required: jack, jack stands, wheel chocks, socket set, torque wrench, OBD-II scanner.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands and ensure the vehicle is stable.

3. Inspect the Suspension Components

Visually inspect control arms and bushings for cracks or excessive wear.
Check struts for leaks or damage.
Tighten any loose bolts to manufacturer specifications.

4. Inspect Brake Components

Remove the wheel using a socket set.
Check brake pads for uneven wear or thickness.
Inspect rotors for grooves or warping.
If necessary, replace worn brake pads and machine or replace rotors.

5. Reinstall Components

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications.

6. Test Drive

Take the vehicle for a test drive to ensure the grinding noise has been resolved.
