Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding with repairs.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the brake components for any additional issues while the wheel is off.

4. Remove the Axle Nut

Use a torque wrench to remove the axle nut securing the CV joint to the hub.
If it’s stuck, a penetrating oil may help to loosen it.

5. Detach the CV Joint

Use a pry bar to carefully separate the CV joint from the hub.
Be cautious not to damage other suspension components during removal.

6. Inspect and Replace Components

Inspect the CV joint for wear. If damaged, replace the CV joint assembly.
If only the boot is damaged, remove the old boot and clean the joint before applying new grease and installing a new boot.

7. Reassemble

Reattach the CV joint to the hub and torque the axle nut to the manufacturer's specifications (usually around 250 Nm).
Reinstall the wheel and torque the lug nuts to the specified setting (often around 120 Nm).

8. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back onto the ground.
Reconnect the negative battery terminal.
