Jack the machine up there will not be any tension on the shock at that point, remove wheel, and shock, remove brake caliper, remove axle nut, remove ball joints at spindle, remove tie rod at spindle, careful not to pull on axle, if your axle is stuck in the spindle pull your axle with it, you can seperate them on a workbench, still do not pull on axle at boot area you can pull the pucks out. After you get axle out of spindle remove snap ring, you will prob have to drive old bearings out, clean out your bearing boss and re assy, your axle nut will torque at 55ft lbs
