By using the pair of pliers, you have to remove the cotter pin which attached to the knuckle on the tie rod. Take a wrench and remove the nuts.

Take the knuckle off the ball joints and reinstall it with the new steering knuckles and tighten all the bolts well. Repeat the same process for the other side of the jeep.
