The key to keep from stripping the spline's from your tool is to make
sure the socket in the bolt head is clean! Also have the tool straight.
    I use a pocket screw driver to clean out the head, then I take a hammer
and tap the tool in until it bottoms in the bolt. This and keeping it
straight will make them last. I use a 3/8 drive pistol grip impact wrench.
    If I can't get to the car with air, and have to do it by hand. I make
sure the car is in neutral and hold the ratchet and turn the tire. I seem to
get better leverage that way. Again keeping it straight.
