Rear axle

Oil recommendations
On vehicles with single gear, the oil is filled up to the
edge of the level hole.
On vehicles with hub reduction, the hub is first filled
with oil in accordance with the table above. The
differential is then filled with oil up to the edge of the
level hole.
For a number of reasons not all rear axles can have the
same service recommendations. They have therefore
been divided into service categories.
The service categories, numbers or letters, can be
found on the ID plate on the final drive. The categories
are G, 1 and 2.
Two different service recommendations can be applied
to rear axles:
• Standard service recommendation
• Alternative service recommendation
The alternative service recommendation provides
longer service intervals than standard service
recommendation. The alternative service
recommendation demands the use of special oil.
The standard service recommendation and alternative
service recommendation both consist of three parts.
The three parts are oil grade, viscosity and service
intervals. These can be found in the same order on the
following pages.
The following procedure can be very useful when
deciding which oil to use.
1 Find out which service category the component
belongs to
2 Use the information in the table under Service
intervals and decide which service
recommendation will be used
Note!
If the rear axle has no entry under
service category on the ID plate, it
belongs to service category G.
