My 3.55 final drive has a little whine under load. Not enough to really DO
anything about, but slightly annoying. So I'm considering adding some MSO2
to try to quiet it a little. Before doing so, I thought I'd Google for
others' experience. Here's the only reply whose title seemed to address
noise:
"In this work, we present a study on the negative differential resistance
(NDR)behavior and the impact of various deformations (like ripple, twist,
wrap) and defects like vacancies and edge roughness on the electronic
properties of short-channel MoS2 armchair nanoribbon MOSFETs. The effect of
deformation (3°–7° twist or wrap and 0.3–0.7 nm ripple amplitude) and
defects on a 10 nm MoS2 ANRFET is evaluated by the density functional tight
binding theory and the non-equilibrium Green`s function approach. We study
the channel density of states, transmission spectra, and the ID–VD
characteristics of such devices under the varying conditions, with focus on
the NDR behavior. Our results show significant change in the NDR peak to
valley ratio and the NDR window with such minor intrinsic deformations,
especially with the ripple."
SO, can someone please advise me whether to expect quieter final drive
operation with MSO2?

MoS2 is, molybdenum disulfide which is a water insoluble lubricant. I have no idea as to what MS02or MSO2 are.

Ken, turn the radio up. If that doesn't work, try the MOS. I have used
both. Molybdenum is great stuff. Don't know much about it's ability to to
quiet gear whine, but if I had to guess, I would say that it is somewhat
limited.

Mac,
You're absolutely correct. But the erroneous "MSO2 Grease" has become such
common usage that "MoS2 Grease" is less used: 246,000 Goggle replies vs
233,000 for the correct term! Shamefully, I've subconsciously fallen into
using the wrong term. :-(

Molybdenum disulfide, MoS2.
It will run cooler. Not that it would be noticeable hooked up to an engine.
There will be less wear. although that has generally not been a problem.
However adding it will not hurt anything and it just might help with noise. If you decide to add the MoS2. Let us know how iif it worked.

The information you found sounds like someone was giving a lot gobble de gook or pseudo science.

Ken,
I think this explains it quite clearly:
"We establish the theory for perfect transmodal Fabry-Perot interferometers that can convert longitudinal modes solely to transverse modes and vice versa, reaching up to 100% efficiency. Two exact conditions are derived for plane mechanical waves: simultaneous constructive interferences of each of two coupled orthogonal modes, and intermodal interference at the entrance and exit sides of the interferometer with specific skew polarizations. Because the multimodal interferences and specific skew motions require unique anisotropic interferometers, they are realized by metamaterials. The observed peak patterns by the transmodal interferometers are similar to those found in the single-mode Fabry-Perot resonance, but multimodality complicates the involved mechanics. We provide their design principle and experimented with a fabricated interferometer. This theory expands the classical Fabry-Perot resonance to the realm of mode-coupled waves, having profound impact on general wave manipulation. The transmodal interferometer could sever as a device to transfer wave energy freely between dissimilar modes."

Ken, Ken, Ken. Don’t tell me you’ve forgotten your Green’s Function for
solving inhomogeneous differential equations?
Actually, it’s research paper review time of year again. I’ll have half a
dozen of these to try to understand we’ll enough to refute.

Ken,
What did you do?
Did you join facebook? I notice you did not give us the link.
Back in the 60's when we had a noisy differential, we use to cut up a few cork bottle stoppers and add them into the differential. A little bit of driving and they got ground up and mixed with the oil.
I am not sure of the long term effect, but I did do that to a 58 Chevy I had and I drove that car for another 3 or 4 years.

Ken,
Gear lubes, extreme pressure or otherwise, will do little to nothing to
reduce/eliminate gear noise. The noise usually is a result gear set design,
poor machining and wear. This is based on experience of engineers and techs
with upstream oil industry prime movers/gearsets as high as 250K BHP... And
also, on a more practical level, the experience/views of Corvette owners
https://www.corvetteforum.com/forums/c5-tech/3314396-what-gear-lube-for-a-wh
ining-set-of-gears.html
You're probably aware of this (from page 3C1, service manual X7725) "Final
drive gears are not absolutely quiet and are
acceptable unless some abnormal noise is present." This was written for the
OEM final drive but is probably applicable to your aftermarket final drive
as well. My OEM final drive had an annoying whine at about 40MPH. I bought
the GMC from the original owner with about 24K miles on it 25 years ago. I
mentioned it to him during my check ride with him. He said it was there
since new but the dealer told him "some noise is normal"... (I confirmed
that when I found it in the service manual). The noise did not change in the
next 116K miles when I had Cinnabar change it out for the GM 3.42 gear set.
To my surprise (and delight), the "3.42" has no annoying noise.

Ken,
Did you think it might be the bearing at the output shaft.
Did the noise increase.

Thanks to all for the advice. I'm gonna try the MSO2 (MoS2).
Re: The quotation I included. If you REALLY want more of those erudite
discussions, Google "MoS2" -- you'll be rewarded with lots of them. I've
finally figured out where all that comes from: The authors are all
furriners writing in what they THINK is English. They don't realize that
most of us are so poorly educated that we can't understand one sentence of
it! :-)
Jim, I don't think it's bearing noise nor that it's increased. Nor that
it's really anything to worry about. I'm going to try the MoS2 and will
let you listen to it at Amana.

A few years ago I tried Royal Purple oil in the manual trans of my Jeep JK. The change in noise and shifting was significant. I now use their products in all my vehicles, including the GMC.
