The Rear Axle
|
 |
The construction of the rear axle is alike for all models. It is a tubular dead axle with constant tread width and constant wheel camber.
The rear suspension consists two upper suspension arms,
one lower suspension arm, progressive spiral springs, perpendicularly arranged shock absorbers and a stabilizer.
Starting from the chassis number 2 453 081, models with the 16-N engine
were equipped with a lighter rear axle. With the difference of an other gear ratio, these lighter rear axles where also used for the 12-S models.

The Locking Differential:
In place of the standard rear axles there where also rear axles with locking differential available (except models with the 12-S engine and models with the 16-N engine and the lighter rear axle).
A locking differential can at any time subsequently used in a standart rear axle, because the rear axle housing is identical. But it is important to know, that you have to use a special oil, since otherwise the locking differential would be damaged.
