Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a floor jack to raise the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Remove CV Joint

Use a socket set to remove the axle nut; this may require a breaker bar for extra leverage.
Detach the lower control arm from the steering knuckle (if necessary) using a wrench and socket.
Slide the CV axle out of the transmission or differential gently.

4. Inspect and Replace CV Joint

Inspect the CV joint for damage; if damaged, replace it with a new CV joint kit.
If replacing, follow the kit instructions to assemble the new joint.
Apply grease to the new joint as specified in the manufacturer’s instructions.

5. Reinstall the CV Axle

Reinsert the CV axle into the differential or transmission.
Reattach the lower control arm to the steering knuckle and torque to manufacturer specifications.
Replace the axle nut and torque it to the specified value (typically 100-150 ft-lbs).

6. Reassemble Vehicle

Reinstall the front wheels and lower the vehicle.
Reconnect the negative battery terminal.
