The best way?? I replaced the axle shaft with a solid shaft from the junkyard, not sure of the year. Then I got a CAD delete kit from Warn (pretty cheap). This comes with inner and outer axle seals, and a cover plate w/ gasket to cover the hole from the CAD 'pump'. Had to pull out my carrier, but to me this is the most durable way and made sense to me.
Edit: I have seen no ill affects in doing this.
