Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely lifted using jack stands.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints

Tools Needed: Socket set, torque wrench, screwdrivers, pry bar
Sub-steps:
1. Remove the wheel on the side where the noise is occurring.
2. Inspect the CV joint boots for any tears or grease leakage.
3. If damaged, remove the axle nut using a socket and breaker bar.
4. Disconnect the lower control arm and any other components obstructing the CV axle removal.
5. Remove the CV axle from the transmission and replace it with a new one, ensuring proper alignment.
6. Reassemble all components and torque the axle nut to manufacturer specifications (typically around 200 Nm).

3. Inspect and Replace Wheel Bearings

Tools Needed: Socket set, bearing puller, grease
Sub-steps:
1. With the wheel still removed, check for play in the wheel bearing by shaking the wheel.
2. If loose, remove the brake caliper and rotor.
3. Use a bearing puller to extract the wheel bearing from the hub assembly.
4. Clean the hub area and install the new bearing, ensuring it is properly seated.
5. Reinstall the brake rotor and caliper, and torque to specifications.

4. Inspect and Replace Suspension Components

Tools Needed: Wrench set, socket set, torque wrench
Sub-steps:
1. Visually inspect all suspension components for wear, such as bushings and control arms.
2. If any component is damaged, remove it using appropriate tools.
3. Replace with OEM or high-quality aftermarket parts.
4. Reassemble all components and ensure proper torque specifications are followed.
