First park you VX on a good, level piece of ground then find a static marker that is identical on both sides of the truck. I used the screws on the inside rear of the front wheel wells. Take a piece of string with a weight on one end and tape the other end to the screw head so that the weight is just touching the ground and make a mark at this spot with chalk or something. Now measure from the screw head to your mark. This will allow you to get a clean height measurement on both sides. Adjust your torsion bars accordingly then roll the vehicle back and forth a few times to let the suspension adjust. Make new marks and remeasure. Rinse and repeat until both sides are even.
