2008 G35x Knocking Noise at Highway Speeds


My 2008 G35x has recently developed a noise that only happens at highway (greater than 50mph) speeds. If I slightly move my steering wheel to the right, there is a knocking sound that seems to come from the front passenger side area. I recently replaced my left front wheel bearing thinking that this may be the culprit, but the noise is still present.

I jacked up the car to see if there were any bushings cracked, but I didn't see anything on either side. I then grabbed the right front tire at 9 and 3 and moved it back and forth to listen for a noise. What I heard pretty much sounded like what I hear on the highway. Does anyone have an idea as to what it could be?

I uploaded a video to youtube of the noise:

Any help would be greatly appreciated. Chasing this noise is driving me nuts.
