Description an
d Operation
Loca

tion
The differential
unit
is mounted between the wide mount ing bracket, pendulum assembly and the wishbone tie assembly.
Two tie rods are fitted between top rear of the final dr ive casing and the front of the wide mounting bracket.

Parts List
Description
The
type 14 HU final drive assembly is a hypoid unit with th
e pinion arranged on the cross-car centerline. The driveshaft
coupling utilizes a cassette type pinion oil seal, which is an in tegral part of the pinion flange. This type of seal cannot be
separated from the pinion fl ange and therefore may only be renewed as a complete seal / flange assembly
The axle shafts are driven by the output flanges which rotate on sealed bearings , these assemblies being retained in the
final drive unit by circlips.

Release the axle shaft 1. Remove and discard the (4) nuts axle shaft to differential output shaft
2. Clear the axle shaft from the output flange studs
3. Remove and keep safe the camber shim
10. NOTE: The axle shaft nuts may damage the studs upon
removal; check the thread conditio n by engaging a new nut 2 or 3
threads by hand.
Inspect the output flange studs and renew if there is evidence
of damage / distortion
