Solution

1. Preparation

Tools Required: Jack stands, wheel chocks, impact wrench, brake cleaner, torque wrench, OBD-II scanner.
Safely lift the vehicle using a jack and secure it with jack stands.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect Brake Components

Remove the wheel using an impact wrench.
Inspect brake pads for wear; replace if less than 3mm thickness remains.
Check the brake rotors for scoring or uneven wear; replace if necessary.
Clean the brake components with brake cleaner to remove dust and debris.

3. Inspect Drivetrain Components

Check the CV joints and axle boots for damage or wear.
Inspect the differential and drive shafts for any signs of leaks or wear.
Tighten any loose bolts on the drivetrain components to manufacturer specifications.

4. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 100-120 ft-lbs).
Reconnect the negative battery terminal.
Lower the vehicle and perform a test drive to ensure the grinding noise is resolved.
