– Check axle mountings also for following damage:
♦ Complete separation of rubber and metal parts.
♦ Large play between mounting and suspension link, which
has a considerably negative effect on the function of the
mounting.
Note
♦ Superficial cracks and cuts as well as minor separations of
the rubber element from the metal part do not significantly
affect the operation of the elasto-kinematic mounting and do
not constitute a basis for a complaint.
♦ Damage to the thin rubber skin over cavities due to con‐
struction is also permissible.
♦ Play between bearing and axle component is permissible as
long as there is no negative effect on the function of the
bearing.
4.2
All-wheel drive coupling: changing oil
NOTICE
On vehicles with all-wheel drive coupling the drain plugs
and sealing plugs of both systems are often interchanged
owing to the integrated housing construction of all-wheel drive
coupling and final drive. Caution must be exercised during
maintenance and servicing as incorrect fitting can cause the
all-wheel drive coupling and the final drive to fail.
The all-wheel drive coupling and the final drive are one sys‐
tem with separate oil systems.
