Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, grease, CV joint replacement kit.
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.
3. Inspect the CV joint boot for tears or leaks. If damaged, proceed to replace the CV joint.
4. Remove the axle nut using a socket wrench.
5. Disconnect the lower control arm from the hub if necessary to free the axle.
6. Pull the axle out of the transmission carefully.
7. Install the new CV joint by reversing the removal steps, ensuring proper torque specifications for the axle nut (usually around 200 Nm).

3. Inspect and Replace Control Arm Bushings

Tools Required: Socket set, torque wrench, bushing removal tool.
Sub-steps:
1. With the vehicle still lifted, locate the control arm bushings and visually inspect them for cracks or excessive wear.
2. Remove the bolts securing the control arm to the chassis.
3. Use a bushing removal tool to extract the old bushings.
4. Install the new bushings and reattach the control arm, tightening the bolts to manufacturer specifications.

4. Inspect Wheel Bearings

Tools Required: Torque wrench, socket set.
Sub-steps:
1. Spin the wheel by hand and listen for grinding noises indicating a failing bearing.
2. If a bearing is suspected to be faulty, remove the wheel and hub assembly.
3. Replace the wheel bearing with a new one, ensuring proper lubrication and installation.
4. Reassemble all parts and torque them to specification.
