Mitsubishi Outlander XL. Manual — part 1274

REAR AXLE FWD

M22700000020USA0000010000

The rear axle has the following features:

｠

The wheel bearing is a unit ball bearing (double-row
angular contact ball bearing) which incorporates the
oil seals and is highly resistant to thrust loads.

｠

The number of parts has been reduced by
integrating the magnetic encoder for ABS wheel
speed detection into the wheel bearing.

REAR AXLE AWD

M22700000030USA0000010000

For the rear axle, the unit bearing (double-row angular
contact ball bearing) in which the hub and ball bearing
are incorporated has been adopted for the wheel
bearing, and the EUJ-ETJ type constant velocity joint
for the driveshaft.
The following features are also available.

｠

The lightweight and compact EUJ type constant
velocity joint has been installed on the wheel side
of the driveshaft, and the lightweight compact ETJ
type constant velocity joint has been installed on the
differential side.

｠

Adoption of the electronic control AWD optimizes
the size of the driveshaft constant velocity joint and
reduces weight.

｠

Lead-free grease for the constant velocity joint has
been adopted.

｠

Hexavalent chromium has been eliminated from the
dust cover material.

｠

The number of parts has been reduced by
integrating the magnetic encoder for ABS wheel
speed detection into the wheel bearing.

NOTE:

EUJ (High Efficiency Compact Undercut 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.

With the introduction of the electronic control AWD,
the electronic control coupling has been installed in
front of the differential.
The electronic control coupling transfers the drive
force to the rear wheels by pushing the clutch in
according to the strength of the magnetic attraction

generated by the magnetic coil (For more details, refer
to Electronic Control AWD P.27-18).
The following features are also available.

｠

Aluminum differential carrier reduces weight.

｠

Optimization of the hypoid gear ratio reduces the
torque loss.

｠

Adoption of the hypoid gear with the same teeth
height increases the strength of the coupling.
