Make sure the nose strut isn't over inflated or sticking, when the strut is extended in flight the torque links are designed to sit against a flat on the main nose strut keeping the nosewheel straight ahead and "breakout" springs in the steering rods allow the rudder bar to move still, if over inflated then the noseleg is in effect locked straight ahead, so you have only rudder input to keep it going in the direction you want and no nosewheel steering, either that or it could be a draggy brake. Goes for both Piper and Cessna, though some Pipers do have solid rods on them.
