Lesson 2/Learning Event 2
The geared hub includes a drive gear and a driven gear enclosed in a housing. The drive
gear is turned by the differential-driven half shaft and powers the driven gear which turns
the wheel spindle.
The geared hub is joined to the upper and lower control arm by ball joints bolted to the
outer end of each arm. The driven gear is splined to the wheel spindle, and the drive gear
is turned by the differential-driven half shaft. The radius arm and cover (steering arm and
cover) is connected to the center bar by the tie rod.
