I'm going to be installing my Kaaz this weekend and forgot to order the diff fluid and I doubt anyone in town sells it. I was wondering if there was an alternative that just as good. Maybe some good oil with the GM LSD additive that I've heard about?

Just so you know, the diff is not new, I bought used from a local guy, so it has already been broken in and its already installed into the pumpkin, i just have to swap them out. Any suggestions?

 

Anyone?

 

It says any *non synthetic* 85w-90 GL-5. Which means petroleum stock oil - should be pretty easy to get.

I didn't realize that, i thought you were supposed to use their oil.

 

any old gear oil and some friction modifier from any gm ford or dare I say chrysler dealership will need to be added as well.
