1996 F-150 and Bronco Workshop Manual
DESCRIPTION AND OPERATION

Operation

The rear axle drive pinion receives its power from the engine (6007) through the transmission (7003) and driveshaft (4602). The pinion gear rotates the differential case (4204) through engagement with the ring gear, which is bolted to the differential case.

Inside the differential case, two differential pinion gears (4215) are mounted on the differential pinion shaft (4211), which is pinned with the differential pinion shaft lock pin (4241)) to the differential case. These differential pinion gears are engaged with the differential side gears (4236), to which the axle shafts (4234) are splined. Therefore, as the differential case turns, it rotates the axle shafts and rear wheels. When conditions require one wheel and axle shaft to rotate faster than the other, the faster turning differential side gear causes the differential pinion gear to roll on the slower turning differential side gear to allow differential action between the two axle shafts.
