My most paranoid diagnosis is (1) the whinning/wavering noise is either
the transmission mainshaft bearing or the 3/4 slider hub (because it
seems to only make this noise in 4th gear...over 50 mph); and (2) the
rumbling/reverberating that occurs during accelleration and under load
and at a lower RPM than the other noise is a right rear cv joint.  A
little "knowledge" and a lot of fear...hope I'm wrong on (1).
