The rear axle drive pinion receives power from the engine through the transmission and
driveshaft. The drive pinion gear rotates the differential drive gear which is bolted to the
differential housing outer flange. Inside the differential housing, two differential pinion gears
are mounted on a differential shaft which is pinned to the differential housing. These
differential pinion gears are engaged with the differential side gears to which the halfshafts
are splined. As the differential gear turns, it rotates the halfshafts and rear wheels.

When it is necessary for one wheel and halfshaft to rotate faster than the other, the faster
turning differential side gear causes the differential pinion gears to roll on the slower turning
differential side gear. This allows differential action between the two halfshafts.
