suspension Question

[Shawndondo]

As i was walking to my H3 the other day it looked like it was leaning to one side. I just thought it was the parking lot, when I went home and parked it in the drive way i took some measurements and yep it sits crooked....i measured 39 inches on the rear driver side (from ground to fender lip) and 40 inches on the passenger side. Also measured from the top of the axle to the bump stop and still an inch different....?

Does the gas tank affect the suspension that much I would think that the suspension wouldn?t sag that much....but hey no engineer.. If anyone has some input please let me know. thanks
