Value changed: Self-locking nut, flex disk to rear propeller shaft or rear axle differential M12

see *BA41.10-P-1002-01H

	Remove/install
	Information on preventing damage to electronic components due to electrostatic discharge		see AH54.00-P-0001-01A
	Notes on self-locking nuts and bolts		see AH00.00-N-0001-01A
		While working on the rear axle care must be taken to ensure that the surface of all aluminum components do not get any scratches, cracks and notches. Otherwise the service life of the of the parts will be reduced.
1	Shift gear into "N" position
2	Switch off ignition	Do not remove ignition key, otherwise the transmission will be shifted into position "P".
3	Secure vehicle on the lifting platform		see AR00.60-P-0100SX
4	Remove exhaust system from flange connection back	Vehicles with gasoline engine	see AR49.10-P-7100SX
4	Remove exhaust system from flange connection back	Vehicles with diesel engine	AR49.10-P-7100SXI
5	Detach propeller shaft (1) from rear axle differential (2)		see AR41.10-P-0050-03SX
		Installation: Attach propeller shaft (1) to rear axle differential (2).	see AR41.10-P-0050-04SX
			see *BA41.10-P-1002-01H
	Clean
6	Clean electrical connector and its surrounding area at controller unit (A13)
7	Unlock and disconnect electrical connector on controller unit (A13)
8	Remove controller unit (A13) from bracket (3)		see AR42.20-P-0590SX
