Lesson 2/Learning Event 2
The differential case consists of steel castings bolted together to form a single solid unit.
The right and left ends are machined to provide for the mounting of tapered roller
bearings. These roller bearings support the entire differential assembly in the axle
housing. The differential will rotate in the same direction as the wheels and tires. The
axle shafts enter the differential assembly from the right and left side. The ring gear of
the final drive is bolted or riveted to a mounting flange on the differential case.
