power steering problems

Jack the car up so the front wheels are off the ground.
loosen the bolts slightly on the valve on top the box,
Start the engine, With a small hammer tap the valve
to the front and then to the back of the car, the wheel will spin
one way then the other way. when you get it centered they will stay straight.
Start the car several times watching the steering wheel if it kicks left or right do a fine adjustment till it stops kicking.
