An equipment that is specifically developed to be used in the removal and installation of torsion bar will be needed to carry out the following tasks. Start by turning the front wheels forward to the straight position, lifting the automobile and putting it on jackstands. Disconnect the torsion bar cover plate from the frame of the vehicle. Ensure that no alterations have been made to the torsion bar and take a measurement of the extent that the torsion bar adjustment bolt has to travel on the adjustment nut so that this will be useful later. Screw the special tool onto the cross-member and the torsion bar adjuster to the specified torque and the latter must rise from the adjustment bolt. Remove the adjustment bolt from the torsion bar nut, and determine the number of turns done- you are to note this number. The adjustment bolt and nut are then to be taken out, and the new one must be used while the old one is discarded because it has a special adhesive that makes it impossible to back off easily. Loosen the torsion bar tool until there is no tension on the torsion bar, place a mark of the relation between the torsion bar and the adjuster, lower the adjuster, and pull the torsion bar out of the lower control arm finally removing the insulator. In installation, the procedure is reversed and make sure a new adjustment bolt that you have is coated with adhesive from the factory. Replace the old bolt with a new one, turn the bolt with the same amount of turns as the old one was turned then measure the height of the bolt from the adjustment nut and check this measurement against the previous measurement. The following are the procedures one needs to follow to adjust torsion bars after lowering the vehicle; make sure the vehicle rests as close to level from side to side as possible on available suspension while seating and rotating the torsion bar adjustment bolt. Drive your car backward and forward and bounce the suspension before and after, between position changes, and get the front-end alignment either at a dealer or better yet, at an alignment center.

Before removing or adjusting the torsion bar(s), measure the existing ride height, which is the difference in measurement to the ground from the center of the lower arm's inner mounting bolt and the lowest part of the spindle. Position the front wheels straight ahead, raise the vehicle, and support it securely on jackstands. If the vehicle has Automatic Ride Control (ARC), ensure the air suspension switch is turned off before raising the vehicle to prevent damage to the system components. Disconnect the torsion bar protector from the frame, then unscrew the bolt from the torsion bar nut while counting the number of turns for later reference. Use a heavy-duty two-jaw puller to raise the adjuster, ensuring the puller has an adjustable bridge to prevent the jaws from spreading under pressure. After tightening the nuts on the bridge, remove the torsion bar nut and lower the adjuster. Slide the torsion bar into the lower control arm and remove the adjuster, followed by the torsion bar itself. For installation, reverse the removal steps, ensuring to lubricate the threads of the adjuster nut and use a new adjuster bolt coated with a special adhesive. When installing the adjuster bolt, screw it in the same number of turns as the old one, plus two additional turns. Adjust the ride height as necessary to ensure the vehicle is level from side to side while sitting on its suspension. If the vehicle has ARC, disconnect the air lines from the shock absorbers before making adjustments, and roll the vehicle back and forth while jouncing the suspension before and between adjustments. Finally, have the front-end alignment checked by a dealer service department or an alignment shop.
