Support the front axle with a floor or transmission jack and remove the shocks and the stock upper shock mounts. Separate the tie rod from the pitman arm and then remove the stock pitman arm with a pitman arm puller. Remove the sway bar links on both sides at the upper mounts. Save the 12mm bolts for the reassembly. Since you’re already there, remove the upper sway bar mounts from the inside of the frame and relocate them under the frame as shown. Using the existing holes, bolt the mount down.
