2 Drain oil out of front axle transmission (1) TORQUE SPECIFICATION Drain screw at front axle transmission *BA33.30-P-1008-03G 
3 Detach collar nut (4m) using retainer wrench from drive flange (4) and remove adjusting ring (4a) from drive flange (4) NOTES  
    SPECIAL TOOL Counterhold retainer wrench using locking handle. To do so, an SPECIAL TOOL assembly wedge must be placed between the breaker bar and the front axle carrier.
Otherwise damage may occur.
IMPORTANT The SPECIAL TOOL retainer wrench is secured to the drive flange with just one bolt (4).
