Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and pry bar.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Remove the wheel by loosening the lug nuts and lifting the vehicle with a jack.
- Secure the vehicle on jack stands.
- Visually inspect the CV joint boots for tears or grease leakage.
Replace Damaged CV Joint:
- If damage is found, remove the axle nut and any associated fasteners.
- Use a pry bar to separate the CV joint from the hub assembly.
- Remove the axle from the transmission side and replace the CV joint or full axle assembly as necessary.
- Reinstall all components and torque the axle nut to the manufacturer's specifications (typically 100-130 ft-lbs).

3. Inspect Wheel Bearings

Check Wheel Bearings:
- Remove the wheel and brake caliper for access.
- Manually check wheel bearing play. If excessive play is detected, replace the wheel bearings.
Replace Wheel Bearings:
- Use a bearing press to remove the old bearings from the hub and install the new ones.
- Ensure proper lubrication and reassemble the hub.

4. Reassemble and Test

Reinstall the wheel, tighten the lug nuts to the factory torque specifications.
Reconnect the battery and lower the vehicle.
Take the vehicle for a test drive to check for the grinding noise.
