Raise the front of the Nissan hardbody and place jack stands under the front end directly underneath the bars of the frame.
Crawl underneath the front end and locate the torsion bar and bolt. The bar has two bolts, one on each end. The bolts are on the underside facing the ground.
Turn the torsion bar bolt in a counter clockwise direction to lower it and a clockwise direction to raise it. Do this for each side, turning each one the same number of turns to keep the sides level.
Lower the truck to the ground to check the height. Re-adjust the torsion bar bolts as desired.
Jack up the rear end of the Nissan hardbody. Place a jackstand on each side underneath the frame to hold the truck up.
Remove the U-bolts on each side of the rear suspension by unbolting them from the leaf springs. Do one side at a time.
