Sounds like the strut bearing is going out on you. It is mounted on top of the strut. With the car off the ground, the weight of the car is off of it and the only pressure is from the strut spring load.

Have someone turn the wheel while you put your hand on top of the strut tower under the hood. You will probably feel the bearings crunch.

I have seen these fail in less than 4 years. When struts are replaced, these should be replaced also or you wind up tearing it all out again. The same goes for when the bearing goes out. You might as well change the struts at the same time.
