    • 1). Fill your tires to the recommended psi (pounds per square inch) by your manufacturer. They must all hold the same pressure. Empty any heavy load from the trunk or truck bed. Park the vehicle over solid, level ground, and set it in park or neutral, depending upon your transmission type. Apply the emergency brake.

    • 2). Place a tape measure at the center of your wheel hub, and measure the distance from the wheel hub to the bottom of the fender well lip. Measure all wheels and record the distance for each. Use a floor jack to lift the front end of the vehicle, and place two jack stands under the outside frames or under the frame cross-member. You need the weight off the torsion bar.

    • 3). Refer to your owner's manual for the location of the torsion bar adjusting bolt. Look for a recessed hole in the bottom of the anchor arm. Some adjusting bolts will be located far back behind the engine, near and underneath the front and side passenger doors. See if the bottom bolt extends up through the anchor arm and has a main nut or main and locking nut above the anchor arm. Spray penetrating oil on the anchor arm bottom bolt and top nuts. Let soak.

    • 4). Place a large socket on the bottom anchor bolt head, then turn it clockwise a few complete revolutions. Use a breaker bar for added torque strength. Have your assistant measure the wheel side you have just adjusted. If the gap has changed and increased, continue to turn the socket until you have your desired height. If the measurement did not change and you have a locking nut on top, loosen the locking nut with a socket and repeat the bottom bolt adjustment. Then tighten the locking nut with the socket.

    • 5). Move to the other side of vehicle and place the socket and breaker bar on the bottom bolt. Turn it the same amount of revolutions you did with the other. Have your assistant measure the wheel and tell you the distance in the gap.

    • 6). Keep turning the bolt inward until you meet the same gap as the other wheel. If you need to raise the front end of the vehicle equal with the rear, adjust both sides until all four wheels match. Remember to retighten the locking nuts if you loosened them.

    • 7). Lower the floor jack and remove the jack stands. Take the vehicle for a ride. Make several abrupt stops, and drive over any curves or parking humps to seat the torsion bars. Bring the vehicle back and recheck all the wheel measurements. Perform the adjusting process again if you have one wheel lower or higher than desired.
