HiRay,
I don't see that anyone has aaddressed your post yet...

in my experience ..it's not the side bearings ..
it's the output flange being loose on the splined shaft it sits on.

in two cases I just tried  another less-worn output flange and that took
care of it.
My recommendation is never touch the side bearings adjustment.
   - maybe if you knew it was in really bad shape there and were just
trying to get a few more miles .
but otherwise..
that's a critical adjustment.  It affects ring gear left-right position
and gear contact patternon the pinion gear, and preload there too.  So
no-touchey ever in my book, unless you are doing a whole set up on the R
& Pand you really know what you are doing.

80 W 90 GL-5 sounds good to me for the final drive section.
I wouldn't use the MT-90there. ..it's a GL-4 for syncronizers .
