Steering noise

it might just need some air worked out of it.jack the front of the car up till the wheels are off the ground.place safety jacks under the car so when you turn the wheel hard left or rite the tires wont hit the jacks.release the power steering resivoir cap,start the car and turn the wheel left and rite for about 2 minuets.tighten back up the cap,remove the jacks and take it for a ride.
