Solution

1. Preparation

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

2. Inspect and Replace CV Joints

a. Raise the vehicle using a jack and secure with jack stands.
b. Remove the wheel on the side where the noise originates using a socket set.
c. Inspect the CV joint boot for cracks or tears; if damaged, replace the CV joint.
d. To replace, remove the axle nut with a socket, then detach the CV joint from the hub.
e. Install the new CV joint by reversing the removal steps, ensuring to torque the axle nut to manufacturer specifications (usually around 150-200 Nm).

3. Check and Replace Wheel Bearings

a. With the wheel removed, grasp the wheel hub and check for any play or roughness by rotating it.
b. If the bearing is faulty, remove the brake caliper and rotor to access the bearing.
c. Use a bearing puller to extract the old bearing, and install the new bearing using a press.
d. Reassemble the brake components and wheel, ensuring all fasteners are torqued to specifications.

4. Inspect and Repair Suspension Components

a. Visually inspect the suspension components for signs of wear or damage.
b. Replace any worn struts, control arms, or bushings as necessary. Use appropriate tools such as a wrench and socket set.
c. Ensure all bolts are tightened to the correct torque settings specified by the manufacturer.
