Here’s a cool trick for freeing the unitbearing from the knuckle. Thread the lower rear bolt until it is about 1/2-inch from being tight. Place a socket and extension on the head of the bolt and wedge it against the shock mount as shown. Now start the engine, and use the power steering as a hydraulic press. Slowly turn the steering wheel just a little bit, and the unitbearing will push out of the steering knuckle.
