Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the vehicle.

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 wheels using a socket set.
3. Inspect the CV boots for any tears or signs of leakage. If damaged, proceed to replace the CV joint.
4. If replacing, remove the axle nut using a breaker bar.
5. Detach the CV joint from the transmission and the hub assembly.
6. Install the new CV joint, ensuring proper alignment.
7. Reattach the axle nut and tighten to manufacturer specifications (typically around 250 Nm).
8. Reinstall the wheels and lower the vehicle.

3. Inspect Suspension Components

Sub-steps:
1. Visually inspect upper and lower control arms, bushings, and ball joints for wear.
2. Replace any worn bushings or control arms using appropriate tools (torque specifications vary by component).
3. Ensure all bolts are torqued to the manufacturer’s specifications.
4. Reinstall any removed components and check for tightness.

4. Test Drive

After repairs, take the vehicle for a test drive to ensure the noise has been eliminated.
