So FCA calls for 75w85 GL5 synthetic fluid for front and rear differential service. And NO additional limited slip friction modifier needed.
Red Line makes a 75w90 GL5 in both a limited slip variety and non-limited slip variety.
I want the non-limited slip variety for front and rear, right?
I have the 4.10's with the rear limited slip.
Just checking in for opinions...
(Update: So after digging a little, it seems that the reason that FCA calls for no limited slip additive is that the limited slip function is actually computer controlled. I guess they are using the brakes on the spinning wheel to fool the other wheel into driving... that's a guess.)
