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.

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.

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.

SYMPTOM PROCEDURESM1271004400222
INSPECTION PROCEDURE 1: Abnormal Noise
DIAGNOSIS
STEP 1. Check the rear hub assembly installation bolts for
looseness.
Q: Are the rear hub assembly installation bolts loosened?
YES : Tighten the rear hub assembly installation bolts to the
specified torque 73
7 Nm (54 5 ft-lb). Then go to
St e p 4 .
NO : Go to Step 2.
STEP 2. Check the wheel bearing end play.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Check the bearing's end play. Place a dial gauge against
the hub surface; then move the hub in the axial direction
and check whether or not there is end play.
Limit: 0.05 mm (0.002 inch)
Q: Is the wheel bearing end play within the limit?
YES : Go to Step 3.
NO : Replace the rear hub assembly, then go to Step 4.
STEP 3. Check the rear hub rotary-sliding resistance.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Turn the hub a few times to seat the bearing.
(3) Wind a rope around the hub bolt and turn the hub by pulling
at a 90
angle with a spring balance. Measure to determine
whether or not the rotary-sliding resistance of the rear hub
is within the limit value.
Limit: 24 N (5.4 lbs)
Q: Is the rear hub rotary-sliding resistance within the limit?
YES : Go to Step 4.
NO : Replace the rear hub assembly, then go to Step 4 .
STEP 4. Retest the systems.
Q: Are abnormal noises generated?
YES : Return to Step 1.
NO : The procedure is complete.

WHEEL BEARING END PLAY CHECKM1271000900474
1. Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
2. Check the bearing's end play. Place a dial gauge against the
hub surface; then move the hub in the axial direction and
check whether or not there is end play.
Limit: 0.05 mm (0.002 inch)
3. If the play exceeds the limit, replace the rear hub assembly.
4. After having finished the inspection, install the brake disc,
caliper assembly and tighten the caliper assembly mounting
bolts to the specified torque.

TORQUE CONVERTER STALL TESTM1231005400362
This test measures the maximum engine speed when the
selector lever is in the "D" or "R" position and the torque con-
verter stalls. This tests the operation of the torque converter,
starter motor and one-way clutch operation, as well as the hold-
ing performance of the clutches and brakes in the transmission.
Do not let anyone stand in front of or behind the vehi-
cle while this test is performed.
1. Check the transmission fluid level and temperature. Check
the engine coolant temperature.
Transmission fluid level: At the "HOT" mark on the dipstick
Transmission fluid temperature: 70 80C
Engine coolant temperature: 80 100C
NOTE: Measures transmission fluid temperature with
diagnostic tool MB991958 (MUT-III sub assembly).
2. Check both rear wheels.
3. Pull the parking brake lever on, with the brake pedal fully
depressed.
4. Start the engine. 9 Transmission

The throttle should not be fully open for any more than
five seconds.
If you repeat the stall test when the transmission fluid
temperature is greater than 80
C, move the selector
lever to the "N" position and let the engine run at
approximately 1,000 r/min for at least one minute. Wait
until the transmission fluid temperature returns to 80
C
or less.
5. Move the selector lever to the "D" position. Fully depress the
accelerator pedal and read the maximum engine speed at
this time.
Standard value: Stall speed: 2,100
2,600 r/min
6. Move the selector lever to the "R" position. Fully depress the
accelerator pedal and read the maximum engine speed.
Standard value: Stall speed: 2,100
2,600 r/min
TORQUE CONVERTER STALL TEST JUDGMENT
RESULTS
1. Stall speed is too high in both "D" and "R" range
Malfunction of the torque converter (Slippage on the splines
of the torque converter and the input shaft)
Low line pressure
Low-reverse brake slippage and malfunction of the one-way
clutch
2. Stall speed is too high in "D" range only
Underdrive clutch slippage
3. Stall speed is too high in "R" range only
Reverse clutch slippage
4. Stall speed is too low in both "D" and "R" ranges
Malfunction of the torque converter (Slippage of the
one-way clutch)
Insufficient engine output
HYDRAULIC PRESSURE TESTSM1231005500392
The transmission fluid temperature should be between 70
80C during the test.
1. Check the transmission fluid level and temperature. Check
engine coolant temperature.
Transmission fluid level: "HOT" mark on the dipstick
Transmission fluid temperature: 70 80C
Engine coolant temperature: 80 100C
2. Raise the vehicle so that the wheels are free to turn.
