Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace CV Axles

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the outer CV joints for torn boots or excessive play; replace if damaged.
4. Remove the CV axle nut using a socket wrench.
5. Detach the CV axle from the hub and differential by removing retaining bolts.
6. Install the new CV axle and secure it with the retaining bolts and torque to manufacturer specifications (typically 50-70 ft-lbs).
7. Reinstall the CV axle nut and torque to manufacturer specifications (usually around 150-200 ft-lbs).
8. Reinstall the front wheels and lower the vehicle.

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel as outlined in the previous step.
2. Inspect the wheel bearing for wear or play by spinning it; replace if noise or roughness is detected.
3. Use a bearing puller to remove the old bearing from the hub.
4. Press in the new bearing using a hydraulic press or bearing tool.
5. Reinstall the wheel and tighten the lug nuts to the specified torque.
