TECHNICAL DESCRIPTION
Propeller shaft
The propeller shaft, which is the link up
between transmission and rear axle, is
divided into two sections. The forward sec-
tion is journalled at its rear end in a rub-
berized ring.

Final drive
Engine torque is transmitted via the pro-
peller 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 center line of the drive shafts
.

Limited slip differential
A limited slip differential can be obtained
as extra equipment. A rear axle with a li-
mited slip automatically transmits the trac-
tive power to the wheel having the best
road grip when a wheel begins to spin
.
Except for the differential, the rear axle is
sim ilar in design to a conventionai rear
axle.
Do not rotate a jacked-up rear wheel if the
other rear wheel is still on the ground. Due
to the differential
,
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
ear to topple off the jack.
Rear axle
The rear axle is carried on two support
arms the front end s of which are bolted
to the body. The rear axle casing is se-
cured to the support arms by means of
levers. 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.
