My manual says to change the fluid every 50k. Was wondering what the deal is if I hardly ever use the truck in 4 wheel drive? I'll be changing the rear diff for sure as I'm approaching 60k with no hard driving and/or hauling. Thanks for any advice/info.

the recommended 4X4 fluid replacement of the drive train components is around 30,ooomi...
front rear diff. transfercase , and transmission...also fuel filter...
the components of the drive train cause the fluids to create acids that destroy the metals ,clutches seals....it's your call how much you want out of this vehicle...
I'm going on 10years no leaks or failures yet 125,ooomi...
