My steering wheel reacts almost instantly. I've had a bad box before so I know what that feels like. It steers like a truck (I'm not calling the Jeep a truck, only using it for comparison) with a solid front axle should. The caster definitely contributes to the bump steer, but that's not bad. It's just something she's not used to. She just didn't like driving it and was finding reasons to complain about it. I doubt a new truck, with a similar setup, would steer any better, without regard to the slight bump steer I have. New cars have very sensitive steering, especially when they're equipped with speed sensitive steering. I have a hard time keeping her car straight once it gets up to speed on the highway for the first few minutes. My brain has to get used to the way her wheel reacts.
