  Q: How to replace the torsion bar and support assembly on Chevrolet Express 2500?

  A: Replace the Torsion Bar and support assembly by first supporting and lifting the vehicle. Use j 36202 (Torsion Bar Unloading/Loading Tool) to connect to adjustment arm and support structure before increasing the adjustment arm tension until the adjustment bolt load eliminates from adjuster nut while counting the turns needed until bolt removal. First remove the adjustment bolt and adjuster nut before taking off the j 36202 so the Torsion Bar can unload. While sliding the Torsion Bar towards you remove the adjustment arm. Support its weight with your hand until the arm disconnects from the bar. The first step requires removing the support bolts from the Torsion Bar followed by removal of the Torsion Bar support with careful note taken about the unique positions of left and right torsion bars before extracting them from the vehicle. Position the torsion bars onto lower Control Arms before installing the Torsion Bar support. Tighten the Torsion Bar support bolts to a torque of 95 nm (70 lb ft). Pull the Torsion Bar backward while holding the adjustment arm to enable full engagement between both components. Reconnect the j 36202 tool to its mounting positions on the adjustment arm and support before adding tension to the arm to properly load the bar by turning the adjustment bolt to the same number of turns used for initial removal. Use the j 36202 to remove the cut-out section and lower the Torsion Bar tension until the adjustment bolt assumes the load. Begin by measuring z height with the vehicle lowered then adjust the bolt with a clockwise motion to increase height or counterclockwise motion to decrease height when required.
