Section 05-00: Axle and Driveshaft—Service | 1994 Mustang Workshop Manual |
4 Wheel
The rear axle drive pinion receives power from the engine through the transmission and driveshaft (4602) . The pinion gear rotates the differential case (4204) through engagement with the ring gear which is bolted to the case outer flange. Inside the case, differential pinion gears (4215) are mounted on the differential pinion shaft (4211) which is pinned to the differential case . These pinion gears are engaged with the differential side gear (4236) to which the axle shaft (4234) shafts are splined. Therefore, the differential case turns and rotates the axle shafts and rear wheels. When it is necessary for one wheel and axle shaft to rotate faster than the other, the faster turning side gear causes the differential pinion gears to roll on the slower turning differential side gear to allow differential action between the two axle shafts.
