When I am going down the road and hit a bumb, my rear end feels like the driverside tire hits the ground first then the passenger side. The rearend kind of jerks to one side when it lands. While examening it I noticed that my sway bar to frame mount on the driverside rear is not in the same orientation as the passenger side. The passenger side lines up perfect when I un-bolt and re-bolt it back up. But the driverside doesnt want to line up with the hole in the sway bar. could this have moved over the years or bent? or could this have been like that since the factory? And could this be my problem?
