Default Friction Modifier?

Hello,

I just bought an 03 FX4 manual tranny..
I am doing all the fluid changes for peace of mind and was wondering if I need friction modifier for the rear end? Also do I need it for the Front Axle as well?

The rear axle is 75W-140.. if I use royal purple it has friction modifier in it no?

the Fornt uses 80W-90.. Do I use there too?

Thanks

Read the axle code. And then Decode it here

L/S means limited slip

open mean open gears. (non L/s)

If you have a limited slip you will need modifier.
