2001 Explorer Uneven tilt

[setanda]

Hi, I got a new 2001 Ford Explorer about six weeks ago and the right rear side is one inch lower that the left rear side. What do you guys think is going on here. Got the front torsion bars adjusted, had the dealer replace the rear springs and even dropped down to an almost empty gas tank. The tank is located on the left side thought this may make a difference. This is my first SUV, first Ford and I am not enjoying this.

Thanks, Sean,, USN
