Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Damaged Components

Check CV Joints:
- Remove the wheel on the side where the noise is occurring.
- Inspect the CV joints for any cracks or torn boot seals.
- If damaged, replace the CV joint or axle assembly as needed.
Examine Suspension Components:
- Inspect control arms, bushings, and struts for wear or damage.
- Replace any worn bushings or components using a socket set and torque wrench. Follow manufacturer specifications for torque values.
Check Wheel Bearings:
- Spin the hub while it's off the ground to listen for grinding noises.
- If the wheel bearing is faulty, replace it using a bearing puller and appropriate tools.

3. Reassemble

Reinstall the wheel and tighten the lug nuts to the manufacturer’s specified torque.
Reconnect the battery and ensure all components are secured.
