Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, OBD-II scanner.
Safety Warnings: Always park the vehicle on a level surface and engage the parking brake before lifting.

2. Inspect and Replace Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the brake pads for wear. Replace if less than 3mm of material remains.
4. Check the rotors for scoring or warping. Resurface or replace if damaged.
5. Reinstall the wheel and torque to manufacturer specifications (typically 80-100 ft-lbs).

3. Examine Drivetrain Components

Sub-steps:
1. Inspect the CV joints for any cracks or tears in the boots.
2. Check the driveshaft for any signs of bending or wear.
3. If damage is found, replace the affected CV joint or driveshaft as necessary.
4. Inspect the differential fluid level and condition. Replace fluid if it's low or contaminated.

4. Test Drive and Final Inspection

Sub-steps:
1. Lower the vehicle and perform a test drive to confirm the issue is resolved.
2. Listen for any remaining grinding noises during acceleration and turning.
3. Recheck for any error codes using the OBD-II scanner after the test drive.
