Diff Action --

Refers to how loose or tight a diff setting is. A diff setting that allows the opposing tires to spin freely is said to have a loose or light action, while a diff setting that provides more resistance to the opposing tires is said to have a tight or heavy action. A locked diff would have no action. Diff action can be tuned with the use of thinner or thicker diff fluid or grease. The action of a ball diff is adjusted by loosening or tightening the adjustment nut.
