Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Brake Component Inspection and Replacement

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads and rotors for wear. Replace pads if thickness is below 3mm or if grooves are present.
3. If the rotors are warped or worn, replace them as well.
4. Reassemble the brake components and tighten the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Wheel Bearing Inspection and Replacement

Sub-steps:
1. With the wheel still removed, check for play in the wheel hub. If excessive play is detected, proceed to replace the wheel bearing.
2. Remove the axle nut and hub assembly.
3. Replace the wheel bearing using a bearing press tool.
4. Reassemble the hub and wheel, ensuring proper torque specifications.

4. Drivetrain Component Inspection and Repair

Sub-steps:
1. Inspect the CV joints for any tears in the boot or signs of grease leakage.
2. If damaged, replace the CV joint or axle assembly as necessary.
3. Reassemble the drivetrain components, ensuring all fasteners are torqued to specification.

5. Final Check

Sub-steps:
1. Reinstall the wheels and lower the vehicle.
2. Reconnect the battery and start the vehicle.
3. Test drive to ensure the grinding noise has been resolved.
