I have a 2000 ford expedition with 4wd and rear air bag leveling system. Well the ride on my car is horrible. I can feel every little bump on the road times 10. I was wondering if my SUV has a torsion bar which is twisted(for the lift) because we are certain when we bought it, it had a lift. and the air bag system is leveling them out. In my knowledge twisting the torsion bar for a lift is bad. Could this be the problem of suspension problems?
It's possible the height adjustment on the air suspension has been messed with. If you run the air bags up, that will make the rear stiffer. There is a link between the rear axle the underside of the body that controls the air suspensionCrawl under there see if it's been maxed-out.
