	Removing
1	Remove front axle drive shafts		AR33.30-W-0100A
2	Remove differential lock shift cylinder (3)	 Only with differential lock (interwheel differential lock).
3	Remove through-drive shaft		AR33.30-W-0491A
4	Remove propeller shaft at differential assembly	 Support propeller shaft.	AR41.10-W-0050A
5	Remove differential lock connector (10)	 Only with differential lock (interaxle differential lock).
6	Remove differential lock compressed air connection (8)	 Only with differential lock (interaxle differential lock).
7	Remove differential assembly (6)
	Install
8	Install shift cylinder (3) with parts (4 and 5)	 Only with differential lock (interwheel differential lock).
9	Screw bolt M18x1.5 (1) into the shift cylinder (3) until the differential lock is engaged	 Only with differential lock (interwheel differential lock). Engaging the differential lock prevents the shift collar from falling down when the differential assembly is installed.

13	Tighten bolts (7)		*BA33.30-N-1001-06A
14	Install differential lock compressed air connection (8) with new sealing rings (9)	 Only with differential lock (interaxle differential lock).
15	Install differential lock connector (10)	 Only with differential lock (interaxle differential lock).
16	Install shaft of through-drive		AR33.30-W-0491A
17	Install differential lock shift cylinder (3)	 Only with differential lock (interwheel differential lock).	*BA33.40-N-1002-01A
18	Install propeller shaft		AR41.10-W-0050A
