My rear axle seems to have shifted back about 2". The drive line does not look extended, the spring packs don't show a shift. About 2 years ago I had a Transmission put in and my dad has had the jeep since then. We have a 4" super lift and the leaf packs seem to be facing the correct way but i don't have any measurements to confirm the correct install direction. Any ideas as to how to correct the sift?
