The Mopar OEM 8 3/4 and Dana 60 axle bearings get packed in grease (like front wheel bearings) prior to pressing the assembly on the axle shaft. There is an inner grease seal in the housing that prevents rear end fluid from reaching the wheel bearings.

Thanks for refreshing my memory. At least I got the first part right.
I believe some of the other Mopar axles with c-clips and straight bearings use gear lube?

Re: Ring & Pinion Lube
 

You are correct! After pulling the rear apart I fully understand now. The rear in my car is a complete Moser fabricated unit using a stock housing. It is braced and has a Pro Gear and the axle bearings are sealed. I am still not comfortable with one quart and have put two quarts of Amsoil gear lube in. Boy, that aluminum chunk IS lighter than the iron one! Jim

Re: Ring & Pinion Lube
 

I have a question or an observation,If you want to know how little friction you are creating--why not mount a EGT in the rear and hook it to a data-logger so you can get a play back and look at the run and then make changes.

You can buy paint or tape kits that register temps.

Or, you could just watch the MPH clocks.

Back in the early days of Pro Stock, Bob Glidden fabricated a small sump like kick out in his rear end housing that had a bung welded in it for a heating element similar to a water heater, only smaller. The heater was plugged in between rounds to keep the gear oil up to temp. That was long before synthetic gear oil was up to speed.
