"Wallet lightening?" Well, gear oil changes may be futile if good quality
correct type oil is in there to begin with. But if you don't know for sure
that it is, it seems to me like a very smart thing to do.


Also, there are cheap ($20 or so) yet very useful fluid transfer pumps
available at your FLAPS. They work great for jobs like this, especially for
diffs when you can't use gravity to help you out.

Cheers,
Brady

"Yucky" ?   That's how most gear oil smells.  Many, including old type 
Kendall (one of the best!), look the way you describe.  Be SURE the gear oil

you use in the tranny is "GL-4" and the oil you use in the rear diff is 
"GL-5".  No mixes, no combos, just the straight type.  Gear oil doesn't 
suffer from the deterioration motor oil does, so changing it (other than to 
look at the magnet) is basically an exercise in wallet lightening.
