TECHNICAL DESCRIPTION
Propeller shaft
The propeller shaft, which is the connect-
i ng link between the gearbox and the rear
axle, is divided into two sections. The for-
ward section is flexibly mounted at its rear
end in a rubberized ring.
Final drive
Engine torque is transmitted via the prop-
eller shaft to the rear wheels through the
final drive. The final drive is of the hypoid
type, that is, the drive pinion lies below the
centre line of the drive shafts.

Limited slip differential
On certain markets, a limited slip differ-
ential can be obtained as optional equip-
ment. A rear axle with a limited slip auto-
matically transmits the tractive power to the
wheel having the best road grip when a
wheel begins to spin. Except for the diffe-
rential unit, the rear axle is similar in design
to a conventional rear axle.
Do not rotate a jacked-up rear wheel if
the other rear wheel is still on the ground.
Due to the differential unit, there is still
drive on the wheel in contact with the
ground. Rotating the jacked-up rear wheel
would thus move the other rear wheel and
may cause the car to topple off the jack.
Rear axle
The rear axle is carried on two support
arms the front ends of which are bolted
to the body. The rear axle casing is se-
cured to the support arms by means of
l evers. Two torque rods are journalled on
the casing and the body. A torque rod pre-
vents lateral movement of the body and rear
axle in relation to each other.
