The inboard end of each axle shaft is connected to the transmission via a double offset joint
(DOJ) which can extend and retract in the axial directions.
D
The outboard end is supported by taper roller bearings located inside the axle housing via a
bell joint (BJ) which features a large operating angle. Both the constant velocity joint (DOJ and BJ)
ensure smooth, regular rotation of the drive wheels with minimum vibration.
D
The bearing is a preloaded, non-adjustable taper roller unit type.
Each hub is fitted in the axle housing via the taper roller bearing.
D
The BJ's spindle is splined to the hub and secured with an axle nut clinched to it.
D
The disc rotor is held in position by the hub bolts and wheel nuts together with the wheel. This
facilitates removal and installation of the disc rotor and thus improves serviceability.
