Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and support it with jack stands.
Remove the front wheels using a socket set.

3. Remove the CV Joint

Tools Required: Socket set, impact wrench (if available), CV joint puller.
Remove the axle nut using a socket and impact wrench.
Disconnect the lower control arm from the steering knuckle for better access if needed.
Use a CV joint puller to carefully separate the CV joint from the hub.

4. Inspect and Replace

Examine the CV joint for cracks or excessive wear.
If damaged, compare the old CV joint with the new part to ensure compatibility.
Clean the joint housing and inspect the splines for damage.
If the boot is torn but the joint is intact, replace the boot and repack it with grease; otherwise, replace the entire CV joint.

5. Reassemble

Install the new or repaired CV joint into the hub.
Reattach the lower control arm if it was disconnected.
Torque the axle nut to the manufacturer's specification (typically around 250 Nm or as specified in the service manual).
Reinstall the wheel and lower the vehicle.
