Take out the bolts holding the wheel bearing in. Put the rear most one back in half way. With the steering wheel straigh ahead find a shallow socket and an extension that will bind against the frame rail. Fire the truck up and turn the wheel (binding the socket and extension against the frame rail and the protruding retension bolt.) Apply some good steering imput pressure. hammer the fuck out of the knuckle and the vibrations will loosen things up. Voila, wheel bearing on the ground.
