GENERAL INFORMATION

The rear axle has the following features.

• The wheel bearing is a unit ball bearing (dou-

ble-row angular contact ball bearing) which incor-
porates the oil seals and is highly resistant to a 
thrust load.

• The number of parts has been reduced by inte-

grating the magnetic encoder for ABS wheel 
speed detection into the wheel bearing.

• ETJ-type on the differential side and EUJ-type on 

the hub side constant velocity joints are featured 
in the driveshaft.

• Adoption of the electronic control AWD optimizes 

the size of the driveshaft constant velocity joint 
and achieves the weight saving.

• Adoption of the Super All Wheel Control (S-AWC) 

<Vehicles with S-AWC>

• Lead-free grease for the constant velocity joint 

has been adopted.

• Hexavalent chromium has been eliminated from 

the dust cover material.

• The electronic control coupling installed in front of 

the differential, which transfers the drive force to 
the rear wheels by pushing the clutch in accord-
ing to the strength of the magnetic attraction gen-
erated by the magnetic coil (For more details, 
refer to Electronic Control AWD).

• Aluminum differential carrier is used for weight 

saving.

• Optimization of the hypoid gear ratio reduces the 

torque loss.

• Adoption of the hypoid gear with the same teeth 

height realizes the downsizing and increases the 
strength of the coupling.

NOTE: 

.

EUJ (High Efficiency Compact Undercut Joint): The 

lighter and smaller constant velocity joint com-
pared with the conventional BJ has been 
achieved by adopting the eight small balls.

ETJ (High Efficiency Compact Tripod Joint): The 

lighter and smaller constant velocity joint com-
pared with the conventional TJ has been 
installed.

For the Super All Wheel Control (S-AWC), refer to
