When installing the steering knuckles the lower ball joint nuts have to be tightened to spec first. It can be difficult to tighten the nuts sufficiently if the ball joints want to spin in their sockets. Cook shows how to overcome this by using a large pair of pliers to squeeze the knuckle against the end forging on the housing to compress the ball joint so it won’t spin. Once the lower ball joints are tight you can install the upper ball joint seats and tighten them and the upper ball joint nuts to spec.
