Remove both rear wheels. Take off the rh hub, brake caliper, rotor and caliper bracket. It's not necessary to disconnect the brake hose, just unbolt it and carefully move it out of the way. The axle comes out from right to left, it should come out with light hammer taps. DO NOT hit the end of the axle with a hammer!!! Either use a wood block or a rubber faced hammer. There is a small o ring on the rh side of the axle, don't lose it, it does not come with most axle bearing kits. While it is out, change BOTH axle bearings. If you are unsure of what you are doing, get someone knowledgable to help you.
