Mitsubishi Evolution X. Manual — part 850

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.

FRONT AXLE DIAGNOSIS

TROUBLESHOOTING STRATEGY

M1261005600251

Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a
front axle fault.
1. Gather information from the customer.

2. Verify that the condition described by the

customer exists.

3. Find the malfunction by following the Symptom

Chart.

4. Verify malfunction is eliminated.
