Steering Locking! (EVO replaced already!)

[obrienda]

On Right turns only, my steering locks up bad, braking or not (I mention this because since the truck reached ~20K, the steering would only lock up while braking, now it does it even on clover leafs (highway exit/entrance ramps)!). I've had pump, EVO sensor and steering shaft all replaced on different visits (all warranted). The only thing that greatly reduced the locking up was when I got a new set of tires, but now it has returned after about ~10K miles of tire wear and is worse than ever. Going back to the dealer tomorrow morning (7/6).
