Use 75W-90 non-synthetic gear oil w/ posi additive.

Run the Redline Shockproof (Heavy). You wont be sorry - it's fantastic fluid.

I installed a TA rear end cover about a month ago and refilled it with Lucas 75W90 synthetic and LSD additive.

Guys with Torsens (98+) should use synthetic... guys with Auburns (anything else) should use non-synthetic. And, of course, the posi additive, but I hear the torsens don't need it.

A question for us guys not running an lsd- I need to change the diff. fluid, and was wondering if either the Lucas heavy duty oil

or the Lucas heavy duty oil stabilizer

is any good. The second one says that it's good for differentials, but I'm not 100% sure about using it. I love using it when I change my oil though. Great stuff
