	Remove
1	Detach wheel and tire assemblies of rear axle.		AR40.10-P-1102XG
2	Drain oil from rear axle differential (1).		AR35.31-P-0523XGA
3	Detach propeller shaft (2) from joint flange (4) and secure to prevent it from falling.	Model 463 with engine 176, 177 as of model year 2019	AR41.10-P-0050XGA
		Model 463 with engine 264 as of model year 2019	AR41.10-P-0050XGF
4	Turn joint flange (4) by hand and check end play of bearing.	The bearing must have no axial play. Otherwise the bearing and the gear set in the rear axle differential (1) will be damaged. If there is axial play or if there is wear debris (shavings) in the drained oil,
		↓
		Replace rear axle.	AR35.10-P-0010XG
5	Determine and note down friction torque on joint flange of drive pinion (4).	Determine friction value at approx. 50 RPM Use a cordless screwdriver for the measurement.
		Torque meter	Fig 3
6	Remove twelve-point collar nut (3).	To do so, screw in retainer wrench using 2 screws into joint flange (4) and counter hold joint flange (4) using retainer wrench.
		Retainer wrench	Fig 7
7	Detach joint flange (4).	Puller	Fig 5
8	Remove cover (5).
9	Pry radial shaft sealing ring (6) out of rear axle differential (1) using a suitable tool.	Do not damage the seat of the radial shaft sealing ring (6) in the rear axle differential (1). Otherwise leakage may occur.
	Install
10	Clean seat of radial shaft sealing ring (6) in rear axle differential (1).	Assembly cleaner	*BR00.45-Z-1028-04A
11	Check seat of radial shaft sealing ring (6) in rear axle differential (1) for damage.	If damage is found,
		↓
		Replace rear axle.	AR35.10-P-0010XG
12	Coat radial shaft sealing ring (6) on inner sealing lip with transmission oil.
	Universal hypoid gear oils (specification 235.7)		BB00.40-P-0235-07A
		Do not apply any transmission oil to sitting surface and outer circumference of radial shaft sealing ring (6). Otherwise leakage may occur.
		Replace radial shaft sealing ring (6).
13	Press radial shaft sealing ring (6) into rear axle differential (1).	Drift	Fig 2
14	Install cover (5).
15	Attach joint flange (4) to drive pinion.		AR35.30-P-0472-02XGA
