Rhythmic sound while on the gas 07 Yukon Xl

[wjs0311]

I have a Rhythmic sound that almost sounds like bad tires when I accelerate. The noise is very audible from speeds over 20mph and will go away completely when I shift to N while coasting. The sound follows the rpm of the engine but it does not sound like it is coming from the engine bay. No sound while driving in reverse. No sound at idle. Put new tires on today and sound has continued. New in the last year are two front wheel bearings. My rotor is in rough shape and needs to be replaced but I can't see it making this noise.

Any ideas? Thanks in advance.

Rythmic is almost always drivetrain, a gear, a bearing, splines, yokes, etc. Start with the driveshaft's yoke and u-joints.

Thanks. Could you hear the sound in the video I took? My wife thinks im crazy but I hear it and so do a few other people I've had take a listen.

I did listen to the video but could not hear anything. With tinnitus, I don't hear much anyways but that constant ring.
