You can do it if you have a bearing press. A 9" is the easiest to work on....no having to drain the rearend grease or pull the c-clips.

You'll need to remove the brake calipers and rotors....then unbolt the axle flange from the axle housing. You a slide hammer or something similar to pull the axle out of the housing. The bearing will be pressed on the axle. Just press it off and press a new one on....then reverse install.

If you have a press, this is an easy job.
