I have drove many out, but take the hub off the spindle first and lay flat. You don't want to mess up the wheel bearings. These in the photos seem to of been replaced before, so knocking them out should be of no problem. Line up the splines and tap back in or flip over a lug nut and draw them in. I agree with others here that going with all right hand threads may be best unless you are working on a 100 point show car.
