Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect and Replace CV Joints

Tools Required: Jack and jack stands, socket set, torque wrench.
Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheel on the side where the noise is occurring.
3. Inspect the CV joint boots for tears or leaks.
4. If damaged, remove the axle nut and disconnect the CV joint from the hub.
5. Replace the CV joint or axle assembly with a new part.
6. Reinstall the wheel and torque the axle nut to the manufacturer’s specifications.

3. Examine Suspension Components

Tools Required: Wrench set, pry bar.
Sub-steps:
1. With the vehicle still raised, visually inspect the control arms and bushings for wear.
2. Use a pry bar to check for excess play in the bushings and joints.
3. Replace any worn control arms or bushings, ensuring to torque all bolts to specifications.

4. Check Wheel Bearings

Tools Required: Socket set, bearing puller.
Sub-steps:
1. Spin the wheel by hand to listen for grinding or roughness indicating bearing failure.
2. If noise is present, remove the brake caliper and rotor.
3. Remove the wheel hub assembly and replace the wheel bearings.
4. Reassemble all components, ensuring proper torque settings.
