It shouldnt be to difficult of a job, if you know what your doing.

Assuming this is a front hub,

-Remove the front wheel

-Remove Brake caliper, and hang with clothes hangar, not to put pressure on the line

-Remove rotor

-Remove (36mm?) nut holding the axle on

-Remove axle from Hub Assembly

-Remove 3 bolts holding hub assembly onto the spindle

-Remove Hub

Install in reverse directions.
