Solution

1. Preparation

Gather tools and parts required for the repair.
Make sure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure the vehicle with jack stands to ensure stability while working underneath.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel to access the CV axle and brake components.

4. Remove the CV Axle

Remove the brake caliper by unbolting it from the bracket; hang it using a bungee cord to avoid stress on the brake line.
Remove the brake rotor from the hub.
Unbolt the axle nut using a socket and breaker bar (typically 32mm).
Use a pry bar to detach the CV axle from the wheel hub, ensuring no damage to other components.
Slide the inner CV joint out of the transmission or differential, possibly requiring a gentle tap with a hammer.

5. Install New CV Axle

Compare the old CV axle with the new one to ensure they match.
Insert the new CV axle into the transmission or differential, ensuring it seats properly.
Reattach the wheel hub by inserting the outer end of the CV axle and securing it with the axle nut (torque to manufacturer specifications, usually around 180-220 Nm).
Reinstall the brake rotor and caliper.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove them.
Torque the lug nuts to the manufacturer’s specifications (typically around 100 Nm).
