This is probably a silly question to many of you. If this has been covered a million times already, I apologize. I've read through piles of lift threads here and haven't run across this yet, but I'll admit it may have slipped through the cracks or gotten lost in information overload. Maybe this is simply "common knowledge", but it's a mystery to me.
Is caster measured relative to the chassis or the ground? Meaning, does stinkbug exacerbate caster problems (relative to ground) or is the measurement relative to the frame? If the lift is level, then this would be the same thing, but I know I'm not the only one riding high in the back.
My truck has 850J/863J springs on "L" shocks with yellow caster bushings. It rides nice, especially compared to my previous rig, so I believe that the bushings may have done the trick for me. However, I'd like to level it out. I measure 3" lift front and 5.5" rear with an ARB+winch up front and unloaded rear. I've considered spring spacers up front, but don't want to exceed the limits for my bushings and ruin the handling. Honestly, I'm inclined to swap in 860 rear springs to drop the back down, but this question has been bothering me.
What do you say, Mud? Will lowering my rear springs effect my caster angle for the better or not at all?
