Do you only hear the noise when the vehicle is moving? Have you inspected the rear of the tires to make sure nothing is touching? Was the vehicle aligned after the work was done? Is there anything that changes the sound's pitch? For example, when applying the brakes does it change? Was the new rack and pinion properly bled when it was installed?
If the sound is evident when the vehicle is not moving, open the hood and inspect the accessory drive belts to make sure nothing is making contact.
If possible, record the sound and upload it for me so I can hear it. Let me know anything you can think of that will help me with the diagnosis.
