6	Remove tapered roller bearing cap (2) and dust shield (5) from the rear axle shaft (1).
7	Remove radial shaft sealing ring (3) of tapered roller bearing cap (2)
	Assemble
8	Press radial shaft sealing ring (3) into tapered roller bearing cap (2)	Replace radial shaft sealing ring (3). Fill the space between the dust and sealing lip with grease. Apply a thin coating of grease to the sealing lip. Installation position: Flush, up to max. 0.3 mm in tapered roller bearing cap (2). Drift	Fig 6

9	Slide tapered roller bearing cap (2) and dust shield (5) onto rear axle shaft (1)
10	Slide tapered roller bearing (6) onto rear axle shaft (1)
11	Press tapered roller bearing (6) with the locking plate (8) onto the rear axle shaft (1)	Replace locking plate (8). The flat side of the locking plate (8) must face the slotted nut with right-hand thread (9.1) or the slotted nut with left-hand thread (9.2). The locking plate (8) is put on to ensure that, when pressing on, pressing on only occurs over the bearing inner race The anti-twist lock of the locking plate (8) must align with the milled section of the rear axle shaft (1) as otherwise the rear axle shaft (1) will be damaged. The tapered roller bearing outer race must be rotated throughout the pressing-on procedure, in order to avoid any damage to the tapered roller bearing (6).	AR35.30-P-7351-01GX
