2005 Colorado pickup w/ sport suspension (ZQ8) erratic ride height in rear of vehicle causes rear axle misalignment. In the rear, one side of vehicle sits closer to the ground than the opposite side causing rear axle to protrude from wheel well on higher side of vehicle, this causes wheel alignment problems (a dog/crab walking condition) where rear axle steers/leads vehicle, I.e. left rear ride height is lower than right rear ride height and axle is shifted so as right rear wheel protrudes from wheel well of vehicle causing dog/crab walking condition-front wheels are not followed in line by rear wheels T. it appears a simple correction of the ride height by replacement of rear springs/shocks may correct the problem, adjusting rear of vehicle to level ride height is required for proper wheel alignment. Dog walking condition is not caused by crooked bed alignment as per dealer/technician. Dog walking condition causes property damage to wheel when turning into curve with rear leading side of vehicle near curb and can cause pedestrian injury if dog walking vehicle jumps curb due to the dog tracking condition during turning.
