GENERAL INFORMATION

M1261000100994

For the front axle, the unit bearing (double row angu-
lar contact ball bearing) in which the hub and ball 
bearing are incorporated has been adopted for the 
front wheel bearing, and the EBJ-ETJ type constant 
velocity joint for the front driveshaft.
There are the following features.

• The lightweight front driveshaft and compact 

EBJ-ETJ type constant velocity joint have been 
equipped.

• Due to the use of the output shaft, the right and 

left driveshafts have been approximately the 
same in length, reducing noise, vibration, and 
torque steer.

• The front driveshaft spline diameter on the 

wheel-side and differential-side has been 
increased, improving torsional strength.

• The ABS magnetic encoder for wheel speed 

detection has been integrated into the front wheel 
bearing, and the protector cover of magnetic 
encoder for wheel speed detection has been 
equipped to the driveshaft.

• The lead-free grease has been adopted for the 

constant velocity joint.

• Hexavalent chromium has been eliminated from 

the dust cover material and protector cover of 
magnetic encoder for wheel speed detection.

NOTE: 

.

EBJ (High Efficiency Compact Birfield 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.
