Sometimes. Remember that the engine isn't under any load when your
in neutral. The bit about feeling the vibration leads me next to U joints
but since you have 2WD, that would more likely come from the back.

Next time it happens try putting the Jeep in Neutral and see if the
vibration goes away. If it doesn't try lightly pressing the brakes.

If it goes away with pressing the brakes you might have a dragging shoe
or your pads are so thin the wear indicator is making noise.

Good luck,

There isn't really a vibration as much as the squealing noise. It is
very off and on. Squeal for a second or two and then stop for a few
seconds. While driving on the interstate this afternoon at about
65mph, I dropped it into neutral and let the engine idle at about
700~800 rpms. There was no change in the squealing sound as the
engine speed changes. It definately seems directly related to the
vehicle speed though. Being 2wd, about the only thing I can think of
is wheel bearings or brakes, as you mentioned. Thanks for the tip and
I'll check that out.
