All-wheel drive coupling: changing oil  
Note  
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 system  
with separate oil systems.  
-1- Sealing plug for filler hole of all-wheel drive coupling oil  
-2- Drain plug for all-wheel drive coupling oil  
-3- Sealing plug for gear oil filler hole  
-4- Drain plug for gear oil  
Special tools and workshop equipment required
