REAR AXLE
DRIVESHAFT SYSTEM
3. Rear Axle
A: GENERAL
1. EXCEPT DOHC TURBO MODELS
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.
The outboard end of the axle shaft is supported by angular contact ball bearings located inside
the axle housing via a bell joint (BJ) which features a large operating angle. Both the constant ve-
locity joints (DOJ and BJ) ensure smooth, regular rotation of the drive wheels with minimum vibra-
tion.
The bearing is a preloaded, non-adjustable angular contact ball unit type. Each hub is fitted in the
axle housing via the angular contact ball bearing.
The BJ's spindle is splined to the hub and is secured with an axle nut clinched to it.
The disc rotor or brake drum is held in position by the hub bolts and wheel nuts together with the
wheel. This facilitates removal and installation of the disc rotor or brake drum and thus improves
serviceability.

2. DOHC TURBO MODELS
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.
The outboard end is supported by taper roller bearings located inside the axle housing via a high
efficiency compact ball fixes joint (EBJ) which features a large operating angle. Both the constant
velocity joint (DOJ and EBJ) ensure smooth, regular rotation of the drive wheels with minimum vi-
bration.
The bearing is a preloaded, non-adjustable taper roller unit type. Each hub is fitted in the axle
housing via the taper roller bearing.
The EBJ's spindle is splined to the hub and is secured with an axle nut clinched to it.
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.
