Solution

1. Preparation

Tools Required: Socket set, jack stands, safety goggles, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the side where the noise is present using the socket set.
3. Inspect the CV joint boots for tears or oil leaks.
4. If damaged, remove the axle nut using a socket wrench.
5. Use a pry bar to detach the CV joint from the transmission.
6. Replace with a new CV joint, ensuring the boot is properly seated.
7. Reinstall the axle nut to the manufacturer's torque specifications (typically around 30-50 ft-lbs).
8. Reattach the wheel and lower the vehicle.

3. Check and Tighten Exhaust Components

Sub-steps:
1. Inspect the exhaust system for loose hangers or connections using a visual check.
2. Tighten any loose bolts or mounts using a socket set.
3. Replace any broken or damaged hangers as needed.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Check the condition of strut mounts and bushings using a pry bar.
2. If worn, remove the strut assembly by detaching it from the knuckle and upper mount.
3. Replace with new strut mounts and bushings, ensuring proper alignment.
4. Reinstall the strut assembly and torque to manufacturer's specifications.
