Assuming you checked the PS fluid and everything is ok and topped up and that your tire pressure was checked with the tires cold(not driven for 3+ hours) and withing the 32psi recommend range(or a bit more if you like)...

-Jack the front right corner up so the tire is off the ground.
-Grab the wheel at 9/3 and push and pull on it. There should be very slight movement if your steering wheel isnt locked(you will see your steering wheel move a bit with this movement. If you feel any kind of clunk/thump movement your outer tierods might need replacing.
-Do the same but grab the wheel at 12/6. Push and pull on it on the top and bottom. If any movement you might need to change the upper/lower ball joints.
-Shimmy under the car and grab the axle shaft with your hand and try to move it up/down; in/out. There should be very little in/out movement on the driver side and hardly anything on passanger side.
-Inspect the boots for leakage.
-Repeat the same for the other corner.
-Jack the whole front end in the car and inspect bushings underneath for the lower control arm, inspect sway bar bushings and brackets, check endlinks for play.
