Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel on the side where the noise is occurring using a socket set.
3. Inspect the CV joint boots for tears. If damaged, proceed to replace the CV joint.
4. Remove the axle nut using a socket and breaker bar.
5. Detach the lower control arm or any components obstructing the CV joint removal.
6. Pull the CV joint from the transmission or differential and replace it with a new one.
7. Reassemble all components, ensuring proper torque specifications (typically 100-150 ft-lbs for axle nuts, refer to the vehicle's service manual).

3. Inspect and Replace Suspension Components

Sub-steps:
1. While the vehicle is still elevated, inspect the control arms, tie rod ends, and sway bar links for wear or damage.
2. If any components are found to be defective, remove them using appropriate tools (usually a socket set or wrench).
3. Install new components, ensuring they are torqued to manufacturer specifications (refer to service manual).
4. Recheck alignment if any suspension components were replaced.
