How can I tell if I have a body lift?

That measurement really doesn't help with a 12 year old Jeep; we don't know condition of coil springs, vehicle weight/configuration, or tire size and pressure. You are practically pointing to the front body bushing. Look at the front body bushing; from the factory the rubber portion should be about 1" thick. If there is an aluminum or plastic puck or the bushing is 2"+ thick than you have a body lift of some sort. Here is a picture of a factory front bushing from a 2009 JK.
