Wheel Humming

[FL Q45]

Hello forum! I have a 1994 Infiniti Q45 and recently I heard a humming coming from the front end of the car. If and when I am traveling above 20 M.P.H. and I turn the steering wheel to the left the humming starts (and gets louder when I turn the wheel more), but when I turn the car to the right it stops. I replaced the rack and pinion twice and I replaced all four tires with Michelin Pilot Sport A.S. 245/40/18's. Could it be in any way possible that the tie rod end can cause this humming? Can anyone inform me as to what can cause this problem???? Any help is appreciated .......

Thanks in advance
