Sir,

.... a most recent feature though since the Equator passed through the
Poles less than 12 000 years ago !
Have you studied the True Geology ? if so the proof of that mighty
turn around & resulting torque are seen all over the relief, and have
been surveyed with great interest by Dr Don Findlay amongst others !

Your comments re differential rotation are not clear to me though, in
the sense that you do not indicate what is _ in your view _ the cause
of Earth spin !
Still if you intent is to convey some idea of magmatic migration
generating that present Equatorial bulge, consecutive to 90° approx
Earth catastrophic rotation of Earth axis 11 700 years ago, you are
correct.
But if you believe some differential rotation of some alleged magmatic
bands are sliding over one another in the core or mantle, you are
wrong indeed, simply for the reason the hub of a wheel turn in phase
with its periphery .

Again probably re-adjustment of magma underlying the Lithosphere is
taking place right now, since the masses of water having disappeared
and the immense new lakes created artificially would have already sent
the Earth out of the balance if those say buffer system did not exist
to alleviate Mankind crass Ignorance
