DRIVE SHAFT ASSEMBLY
FRONT AXLE26-17
4. If the inner shaft is hard to remove from the transaxle, strike
the bracket assembly lightly with a plastic hammer and
remove the inner shaft.
Do not apply pressure to the wheel bearing by the vehicle
weight to avoid possible damage when the drive shaft is
removed. If, however, vehicle weight must be applied to
the bearing to move the vehicle, temporarily secure the
wheel bearing by using special tools MB991000 and
MB990998.
INSTALLATION SERVICE POINTS
.
>>A<< DRIVE SHAFT AND INNER SHAFT ASSEM-
BLY RH DRIVE SHAFT INSTALLATION
When installing the drive shaft or the drive shaft and inner
shaft assembly, be careful that the spline part of the drive
shaft or the drive shaft and inner shaft assembly do not
damage the oil seal.
.
>>B<< DRIVE SHAFT NUT INSTALLATION
1. Be sure to install the drive shaft washer in the specified
direction.
Before securely tightening the drive shaft nuts, make sure
there is no load on the wheel bearings. Otherwise the
wheel bearing will be damaged.
2. Using special tool MB990767, tighten the drive shaft nut to
the specified torque.
Tightening torque: 226
29 Nm (167 21 ft-lb)

GENERAL DESCRIPTION
REAR AXLE27-2
GENERAL DESCRIPTIONM1271000100326
The rear axle has the following features:
The wheel bearing incorporates a unit ball bear-
ing (double-row angular contact ball bearing) for
reduced friction.
The rear wheel hub assembly combines the hub,
wheel bearing, and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.
ABS rotor for detecting the wheel speeds is
press-fitted to the rear hub.

INTRODUCTION TO REAR AXLE DIAGNOSISM1271004100254
Noise from the rear axle may be caused by defects in
the components.
REAR AXLE DIAGNOSTIC TROUBLESHOOTING STRATEGYM1271004200273
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
rear 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
Procedures.
4. Verify malfunction is eliminated.

3. Connect the special tools (3.0 MPa (427 psi) oil pressure
gauge [MD998330] and adapters [MD998332, MD998900])
to each pressure discharge port.

4. Restart the engine.
5. Check that there are no leaks around the special tool port
adapters.
6. Measure the hydraulic pressure at each port under the
conditions given in the standard hydraulic pressure table,
and check that the measured values are within the standard
value ranges.
7. If the pressure is not within the standard value, stop the
engine and refer to the hydraulic pressure test diagnosis
table.
8. Remove the O-ring from the port plug and replace it.
9. Remove the special tool, and install the plugs to the
hydraulic pressure ports.
10.Start the engine and check that there are no leaks around
the plugs.
