Massive caster variance Side to side
I had one K member that I installed that was so messed up, I could just see that it had excessive negative caster on the right compared to the other side. Closer inspection showed a kink near the strut rod hole. Looking closer, the whole K member was twisted slightly clockwise looking from above and the RH strut rod area was pushed in. I had to swap in another K member and trash the bent one.
