Final Drive Gears and Differential
The final drive gears include the transfer shaft which has a
pinion gear on one end and the differential ring gear which
is driven by the transfer shaft pinion gear. The ring gear is
bolted to the differential case and when rotated drives the
case. The case drives the differential
gearset
and in turn, the
front axle shafts. The axle shafts then drive the front wheels.
The differential gears are typical in design and include; a shaft,
two pinion gears, and two side gears. The final drive gears
and the differential case each are supported by tapered roller
bearings. The transfer shaft and its tapered roller bearings
are set-up with a specific amount of
endplay.
The differential
ring gear and case assembly bearings are set-up with a specific
amount of preload. Follow the service manual procedures for
setting up these bearings to ensure long life of the bearings
and the components they support.
