N: To preserve 'drive line' refine
ment, individual parts, other than fixings, MUST NOT be renewed. In the event
of any balance or driveshaft component related problem, the complete assembly must be renewed. Under no circumstances
may the flexible (Jurid) coupling be remo ved from the driveshaft (or its fixings be loosened). Do not drop or subject the
driveshaft to damage.
1. Disc
onnect the battery ground
lead and raise the vehicle for
access
2. Remove the front exha ust muffler, 30.10.18

3. Re

the transmission flange.
If required, 'match mark'

the transmissi on flang and

Unscrew the fi xings (3)

4. Relea s

5. CAUTION: Under no circumstances must the
flexible coupling (or its fixings) be loosened or removed
from the drive shaft
1. 'Match mark' the FLEX IBLE COUPLING to the
differential DRIVE FLANGE
2. Remove the fixings (3)

6. CAUTION: Ensure that the driveshaft front and
rear sections do not become disengaged. Secure the front
and rear sections to preven t sliding joint disengagement
during transport

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.

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
