Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Inspect and Replace CV Joints

Sub-step 1: Lift the vehicle using a jack and secure it on jack stands.
Sub-step 2: Remove the front wheel on the side where the noise occurs using a socket set.
Sub-step 3: Inspect the CV joint boot for tears and grease leakage. If damaged, proceed to replace the CV joint.
Sub-step 4: Use a 32mm socket to remove the axle nut, then disconnect the CV joint from the wheel hub.
Sub-step 5: Replace the CV joint with a new one and ensure the boot is properly seated and secured.
Sub-step 6: Reinstall the axle nut and torque it to the manufacturer's specifications (typically around 200 Nm).

3. Inspect and Replace Wheel Bearings

Sub-step 1: With the wheel still off, check for play in the wheel hub by grasping the top and bottom of the tire and wiggling it.
Sub-step 2: If there is excessive play, remove the brake caliper and rotor to access the wheel bearing.
Sub-step 3: Remove the wheel bearing assembly using appropriate tools (may require a bearing puller).
Sub-step 4: Install the new wheel bearing, ensuring it's seated properly.
Sub-step 5: Reassemble the brake rotor and caliper, and torque all bolts to specifications.

4. Inspect Suspension Components

Sub-step 1: Check control arms, bushings, and struts for wear or damage.
Sub-step 2: Replace any worn bushings or damaged components as necessary.
Sub-step 3: Ensure all bolts are tightened to the manufacturer's torque specifications.
