Now that is what I call support - not only does Eddie explain in the forum, he even calls me to be sure I understand. [:-] Wait a minute - does that mean he thinks I am slow to pick it up?? [&:]

I think I get it now.

In the front, you want both wheels driving all the time so you get good handling and steering without pulling to one side or the other. The thick diff oil is especially needed when turning as one wheel will tend to lose traction as the vehicle leans into a turn, and you do not want the power going to one wheel.

In the back, you want the wheels to be able to turn different rates as you turn. If they can not, you will lose traction in the rear and tend to fishtail when turning. So thinner diff oil is in order.

In the center, you want both front and rear to be driving so you can get maximum grip on the ground. So again, thick is in order.

I will change mine around and report back how it reacts. Current is 3F, 10R, 7C - I am going to 7F, 3R, 10C.
