Replace the Worn CV Axle Assembly

Safety Precautions: Always engage the parking brake, use jack stands rated for the vehicle's weight, and wear safety glasses and gloves. Ensure the high-voltage system is in a safe state as per the manufacturer's service manual before working near drive units.

Tools Required: Vehicle lift or jack and jack stands, lug wrench, torque wrench, socket set (including axle nut socket), pry bar, and a drain pan for any potential gear oil leakage.

1. Lift and secure the vehicle on jack stands, then remove the wheel assembly from the side with the confirmed faulty CV joint.
2. Remove the axle nut and disconnect the necessary suspension components (typically the lower ball joint or strut mount) to allow the steering knuckle enough clearance to swing outward.
3. Carefully pull the steering knuckle away from the transmission/gearbox to release the inner CV joint from the drive unit. Have a drain pan ready, as some gear oil may escape during removal.
4. Inspect the transmission seal for damage; replace the seal if necessary to prevent future leaks.
5. Insert the new CV axle assembly into the transmission, ensuring the splines are properly aligned and the retaining clip clicks into place.
6. Reconnect the suspension components and the steering knuckle to the axle shaft.
7. Install a new axle nut and tighten it to the manufacturer’s specified torque settings using a torque wrench.
8. Reinstall the wheel, lower the vehicle, and perform a test drive to verify the shaking under acceleration has been eliminated.
