Sure, there is better stuff that will show lower wear over time compared to the the ST stuff, but it's not like it's destroying your differential.I've got Super Tech in there from &8^### mart right now.
My "FRIEND" oke: gave it to me so I put it in.
Is this decent stuff? What's the best out there.
Also, I'm running NO LS additive, for a while truck didn't chatter or anything and will hook up both tires, on blacktop everytime.
Now I think I have a chatter when I turn. Hope I didn't hurt anything. How much LS additive should I add to start with? 2 oz ?
I want just enough to stop the chatter but want it to still hook up.
As far as the LSD additive...I would add one bottle of the Ford stuff and see how it works and do a bunch of tight "figure eights" in a parking lot. If you still have the moaning/groaning after that, then add 2oz at a time until problem is solved.
