Any ring and pinion guru's out there?

Neveruse wheel bearing grease on pinion bearings, carrier bearings, or full floating axle bearings...All the manuals warn against it's use in those areas

Hmmmm, that is not what the factory service manual recommends:

Installation
1. Using a high melting point EP bearing lubricant,
liberally pack bearings and apply a light coat on I.D.
of hub bearing contact surface and O.D. of axle
housing tube.
2. Make sure inner bearing, oil seal, oil seal sleeve,
axle housing oil deflector, and inner bearing race and
oil seal are properly positioned.
3. Install hub and drum assembly on axle housing, exercising
care so as not to damage oil seal or dislocate
other internal components.
4. On the 11,000 axles, place outer bearing cone and
roller assembly on axle housing and press firmly
into hub with hand.
5. On 5200 through 11,000 lb. install thrust washer so
that tang on I.D. of washer is in keyway on axle
housing.
6. Install adjusting nut and complete the installation as
directed under "Bearing Adjustment"
