So I'm finally getting ready to get my lift kit ordered. I've got a really pronouced lean to one side. Is there anything that can cause this lean other than the leaf springs? I've measured both sides and it's about 1.5 inches shorter on the driver's side but looking at both springs, I can't see any difference. Could the u-bolts have rotated around the axle so the springs are actually attached at different heights? The shackles don't look busted. I can't see anything wrong, but then again, I can't see a difference in the springs either. Any other ideas to make sure I'm not buying a replacement I don't need.
