Being able to separate the axle from the hub on the outside is just the luck of the draw. A few very lucky individuals have been able to do it, but from the looks of this thread, for the majority, myself included, that outside connection might as well have been welded in place. I did it using the "inside method." While doable, it is a beast of a job - took me about six grueling hours per side. $120 for a pair of axles sounds incredible - if they're still available, I'd jump at that deal, although I would worry somewhat about the quality of the axles, and the boots, at that price. Depends on how long you plan to keep the vehicle.
