2004-08 Chevy Colorado/Canyon 4WD Torsion Bar Leveling Kit

Installation steps for 2004-08 Chevy Colorado/Canyon Torsion Bar Leveling Kit
1. Place the vehicle on a level surface. Prior to beginning, record ride height on each side of the vehicle by measuring from the center of the spindle to a consistent point on the wheel well. Record these measurements for future reference.
2. Put the transmission in Park or 1st gear (manual transmissions) and chock the rear tires.
3. Raise the front of the vehicle using a jack. Raise it enough to completely unload the front suspension. Place a jack stand under each frame rail just behind the lower control arms for the front suspension. Ease the frame down on to the stands, but leave a slight load on the jack as a safety precaution.
4. Verify the front tires are off the ground and that the suspension is unloaded, or at full extension travel.
5. Locate the torsion bar crossmember. There is a bolt on each side of the crossmember that adjusts torsion bar preload. Measure or mark the exposed length of the adjuster bolt for reference during re-assembly. See Figure 1.
6. Position the appropriate torsion bar puller tool on the crossmember. Be sure the top of the puller tool engages the recess present in most crossmembers. Also be sure the lower end of the puller tool engages a recess on the torsion key near the adjuster bolt.
