Anyone know why my drivers rear side is about 1.5 inches higher then the left? I bought it this way there is no evidence of accidents or repair. My passenger side leaf springs have one of those clamp assemblies that has a broken metal tab that clamps them together. COuld that be it? or could it be something else? I have air shocks with 1 port for charging them it is tee'ed off to the 2 shocks, they should self balance should they not?
