Jack up the front of the car till front wheels are off the ground.. There's two bolts holding the fitting,,, that's on the top of the box, where hose goes on, they're 1/2.. just slightly loosen those bolts, and gently tap the fitting either backward, or forward, the wheels will tend to go one way or the other.. that will adjust your problem.. that's how to centre the "feedback".. you must have accidentally moved that fitting... grant
PS.. DANGER.. don't put your arm thru the wheel when starting it up, cuz it'll hurt when the wheel slams over.. better yet, have some-one hold the wheel at start-up..
