Solution

1. Preparation

Gather necessary tools and safety gear.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent rolling.

2. Inspect and Replace CV Joints

Tools Required: Socket set, jack, jack stands, torque wrench
Remove the front wheel using a socket set.
Use a jack to lift the vehicle, then secure it with jack stands.
Inspect the CV joint for any signs of damage or a torn boot.
If damaged, remove the axle nut and detach the CV joint from the hub.
Replace the CV joint with a new component, ensuring to apply the proper torque to the axle nut (typically 200 Nm).
Reassemble the wheel and lower the vehicle.

3. Examine Suspension Components

Tools Required: Wrench set, pry bar
With the vehicle still lifted, visually inspect suspension parts such as control arms, bushings, and struts.
Use a pry bar to check for play in the bushings and joints.
Replace any worn components as necessary.

4. Inspect Wheel Bearings

Tools Required: Torque wrench, bearing puller
Spin the wheel to listen for noise; any grinding indicates bearing wear.
If needed, remove the wheel and hub assembly to access the bearings.
Replace the wheel bearings if they exhibit play or noise.
