Unloading of diffs...can someone explain

[suicideneil]

Simplest way to explain is a demonstration- grab a wheel, then hit the throttle; the opposite wheel will spin twice as fast as it 'unloads' (same theory with a center diff). Its all to do with the internal gearing of a diff and its design to split power/ allow one wheel to turn faster or slower when turning a corner. Thicker diff fluid will tame then effect, which can help or hinder steering performance depending on the track etc.

I thought that is was something like that...thanks for the info!

So the center diff fluid would be the one to change, correct.

Us thicker center diff fluid if you notice the front tires spinning faster, and growing very big on hard acceleration. If you go too thick You may notice that the truck does not turn as tight as before. The thicker fluid helps the diff put the power to the rear wheels, but will also limit the difference in speed between the front and rear diff when turning.
