Quick Check Of System

With car empty, measure distance from center of rear bumper to ground. Add weight equivalent to a two passenger load to rear of car. Car should begin to level in 4-22 seconds, and final position should be approximately ± 1/2" of unloaded height. Remove weight. After 4-22 seconds car should begin to settle. Final unloaded position should be within approximately ± 1/2 of original measurement.
