Hi all,

I've been wondering about this for a while. When I get on the gas and the drivetrain is under a heavier load, I have what I perceive as a drone coming somewhere from the front. When I let up on the gas it diminishes/goes away. When I'm highway cruisin' and light on the gas, I don't hear it.

Any ideas what this may be? I just recently did my full 90k mile service. This was there before and is still there.
