What could be making a roaring noise in the front suspension of a 1993 Cadillac Seville?

[jack]

The car has over 221,000 miles. It looks like someone replaced the original front shocks because the sensor wires near the top of the shocks can not be plug in because there's no connections for the wires. I have no idea what else may have been replaced by the previous owner and I'm unable to contact him.The transmission fluid level is fine. I tried raising the front of the car and set jack stands under for safety I had my son go through the gears but only noise I could hear was the rotors hitting the lug studs because of the play in the stud holes, which I found out that's normal for the holes to be larger than the stud diameter because the tightness of the wheel lug nuts supposedly eliminate that noise(It doesn't;bad call as for GM). The disc pads are fine and the rotors don't need turning. The tires were in bad shape, so I replaced all the tires and the noise is still there. I'm suspecting either bad bearing hubs or cv joints. You can only hear the noise while driving and seems like when you turn your steering wheel to the right the noise seems to go away. I tried to listen while my son drove by me as I was standing near the road as he drove by in both directions, but I could not hear anything. Any suggestion would be greatly appreciated.
