Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the 12V battery for safety.

2. Tire Inspection

Remove the wheel covers (if applicable) and loosen the lug nuts.
Jack up the vehicle and securely place it on jack stands.
Remove the wheel to access the brake assembly and suspension components.

3. Brake Component Inspection

Inspect the brake pads for wear; replace if less than 3mm thick.
Check the brake rotors for scoring or warping; replace if necessary.
Inspect the brake calipers for proper operation and any signs of seizing.

4. Wheel Bearing Inspection

Spin the wheel hub by hand to check for roughness or grinding; replace bearings if noise is present.
Use a torque wrench to ensure that all fasteners are tightened to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer’s recommended specifications (usually around 100-120 ft-lbs).
Reconnect the 12V battery and lower the vehicle.
Test drive the vehicle to ensure the grinding noise has been resolved.
