After taking off the wheel and shit, take off that bolt right in the middle of the brake rotor! that nut is holing the axle in place. then Take out the strut fork nut from the lower control you'll have to get the axle out by going under the fork, and also take of the lower controll arm bolt from the hub, which will let you pull the axle out. After all that just pull the axle out, you pay need to use something to wedge it out from the tranny. After that just rotate the new one into place and put after thing back together!
Hope this helps!
