Direction of rotation of the axle shaft (arrows)
Locking slotted nuts on the left axle shaft as an example
1. Remove the axle shaft (see Section Removal and installation axle shafts).
2. Screw a pair of wheel bolts into the axle shaft hub flange (1) and clamp them in a vice.
3. Unlock and unscrew the slotted nuts (9).
4. Remove the locking plate (8).
5. Using special mandrels and a press, remove the tapered roller bearing (6) from the axle shaft (1) - try not to damage the ABS wheel sensor rotor.
6. Remove the gasket (4), cover (2) with seal (3) and brake shield (5).
7. Remove the seal (3) from the cover (2) and install a new one in its place, lightly lubricating its sealing lips - make sure that the depth of the seal in the seat of the cover is no more than 0.3 mm.
8. Place the cover (2) on the axle shaft (1), then install the brake shield (5), filling the space between the shield and the seal lips (3) with grease.
9. Place the bearing (6) on the axle shaft (1), pressing it with a NEW locking plate (8).
Caution! The locking plate (8) is installed with the flat side towards the slotted nut and must rest only against the inner bearing race! The anti-rotation lock of the locking ring must be aligned with the machined section of the axle shaft to avoid damage to the latter. Make sure that the outer bearing race rotates during pressing!
10. Install the slotted nut (9).
11. Lock both slots of the slotted nut (9) with the locking plate (8) - the nut must not loosen when the axle shaft is rotated in any direction.
12. Place the rectangular section sealing ring (7) on the bearing (6).
