Axle Shaft Assembly: Description and Operation

GENERAL INFORMATION

For the front axle, the unit bearing (double row angular 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 compared 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 compared with the conventional TJ has been installed.
