Important Note: Before attempting this repair, be aware that this is a job that requires significant mechanical skill and the right tools. Improper removal can damage the CV axle, hub, or other components. If you're not comfortable doing this type of repair, it's best to take your car to a qualified mechanic. You'll also need a proper axle nut socket, a breaker bar or impact wrench, and possibly a wheel hub puller depending on the difficulty of separating the hub from the knuckle. The nut is torqued very tightly.
