I would suspect the CV axle. If you have not replaced the drive axle, you should do a close inspection! One way to narrow down the culprit of driveline noises is to find a smooth and level roadway that is not crowded. Accelerate to around 90 Km/h and take the transmission out of gear, and then gently brake normally. Did the pitch or tone of the noise change, decrease or go away altogether?
I have also seen worn CV axles that caused strange vibrations while driving in top gear on the interstate at steady speed. The more typical telltale of worn CV axles are clicking/ grinding when making a tight turn.
Good luck on sorting out that issue!
