  Q: How to replace the torsion bar and support assembly on GMC Savana 2500?

  A:

  In order to replace Torsion Bar and support assembly, first lift and then support the vehicle. Mount the Torsion Bar unloading/loading tool (J 36202) to the adjustment arm and the support and then apply more tension to the adjustment arm until the load is taken off the adjustment bolt and adjuster nut. To remove the adjustment bolt, mark it and count the required turns before removing it. Remove the adjustment bolt and the adjuster nut and then remove the Torsion Bar unloading/ loading tool (J 36202) thus to allow the Torsion Bar to unload. Push forward dragging/increasing the Torsion Bar forward, and hold the adjustment arm with your hands while it comes out of the Torsion Bar. Next, unfasten the Torsion Bar support bolts and the Torsion Bar support, also paying attention to the position of the left and right torsion bars since they are different. Take out the torsion bars from the vehicle. For installation, position the torsion bars over the lower Control Arm and install the support for the torsion bars followed by support bolts, which tighten the bolts up to 95 n.m (70 lb ft). While holding on to the adjustment arm, move the Torsion Bar totally into the adjustment arm. Replace the Torsion Bar unloading/loading tool (J 36202) and raise tension on the adjustment arm and arm to load the Torsion Bar. Apply the same number of turns for the adjust bolt as used for removal plus the adjuster nut. Take away the Torsion Bar unloading/loading tool (J 36202) to release the tension on the Torsion Bar up to when the load is reduced by the adjustment bolt. Lastly, drop and measure the vehicle z height, tightening and loosening bolt clockwise for increase or counterclockwise for decrease in z height.
