I used a punch or a large screw driver with a hammer to crimp the locking nut. The socket is a 30mm 12 point. I think I got mine at Advance Auto Parts for about $10. Unless you have after market camber arms, the camber is not adjustable. If you only take off the outer bolt of the toe strut, then the toe shouldn't change. I loosened mine because it was easier to get the hub off.

Remember, this is to replace the whole hub, not just the bearing. I haven't seen anything on how to replace just the bearing.
