good to know. I think I will return my standard basic Valvoline and then get the Mobil 1.. just so i dont have to hunt down any additives. wish i had seen this thread before i bought..

if you had to choose between 75-140 and 75-90 which would you choose. it doesnt get cold here in Cali..

The chart on this thread says to use 2.5 ounces of friction modifier to front and rear axle.

This chart says to use 2.5 front and 4 ounces rear..

So, what is the real story?

Also, which rear differential do I have on my WJ 2000 with Quadra-Drive, 4.7 V-8? I believe it to be the Dana 44 but would like verification please.

And...What is the proper Mopar PN for the limited slip additive?

Another question regarding the Limited Slip Additive (LSD).

The link I provided says to "add" the LSD to the differential fluid.

Do you put the LSD into the differential fill hole and then top off with the 75w140?

Ha, I was reading this thread and didn't notice that it's info. pertaining to a WJ, not a ZJ, until more than halfway through it.... lol So, you WJ guys have LSD in the front of your Jeeps as well, huh???
