    How to determine what degree axle shims to use?

    i just cant imagine with such a small amount of lift i would need to shim my axle. I did the same lift in a 2000 jeep and it didnt require any shimming or TC drop. Then again i didnt do the leaf springs in the 2000. I'm just getting a grinding sound on decel that is driving me nuts.
