Figure 16-15. Study the assembled view of the clutch-plate
differential. The clutch packs are sandwiched between the side
gears and differential case. The preload spring applies initial
force to the clutch packs but still allows enough slippage in the
clutch pack for normal differential operation. (Ford)

Figure 16-16. Exploded view shows the clutch pack of a
limited-slip differential. Each clutch pack has the same number
of clutch discs and plates. Note the internal teeth on the friction
discs and the external tabs on the steel plates. Grooves in the
discs and plates reduce the chance of slippage.
