Lift the automobile and detach the front tire. Unbolt the brake caliper and hang it to the side with stiff wire without disconnecting the brake hose, then remove the brake disc. Following this, detach the wheel hub fasteners and remove the wheel bearing and hub unit from the steering knuckle. To install, reverse the removal procedure and ensure that the mating surfaces of the wheel hub and steering knuckle are clean. In case of reuse of wheel bearing and hub unit, re-cut bolt hole threads and replace with new ones.
