Have a question abut the two drive shaft bearings at the pinion end of the drive shaft. I'm refering to the two bearings in the differential. Do those bearings get lubricated soley by the diff oil, or do I need to pack tem with wheel bearing grease?? I can't find a clear and difinitive answer on this. Some literature states you should never introduce any oil other than the diff oil. Need some clear direction if you or anyone knowsm. Thanks
I also read somewhere, that you should never use wheel bearing grease on the front and rear pinion shaft bearings. I really don't know why?

Here Number 2, Under
Propeller Shaft and Pinion Assembly.
It says to oil the bearings with engine oil before reinstalling.
There is one difference that I know of, from the older year truck axles to the newer year truck axles.
GM started using a
oil retainer in front of the rear pinion shaft bearing. You can see it in this
Illustration in front of number 4 arrow.
To retard or slow the return of gear lube back into the axle housing.
Assuring the front pinion shaft thrust bearing is in a continuous bath of gear lube.
Passenger car axles, I believe never used a oil retainer.
The
Chevrolet's 1938 Shop Manual - Cut away illustration shows that there was no oil retainer.
I'm curious does your 1937 1/2 ton rear pinion shaft bearing have a oil retainer?
Can you post pictures of your entire propeller shaft.
Just one other thing.
Just to make sure it is done correctly.
Its a good idea to have someone around that has done a ring gear and pinion adjustment before.
Otherwise you could open up a can worms.
