Your are correct, I went off the deep end and was thinking of rear end oil. Guess I didn’t read your comments clearly. Speed reading does that.

And I agree that rear end oil can work in the OD. However. its thickness precludes proper sun gear “bearing” lubrication and “WILL” eventually cause bearing failure. Ok, so someone who is a casual user of an OD may get away with it but extended OD use like interstate driving will eventually get the bearings in trouble.

I do not recommend rearend oil use in trans or OD….period. I’ve seen the damage. It may be a band-aid for an owner but it is just that, a Band-aid to solve another problem that is then aggravated by use of the Band-aid.
