2004 SUSPENSION
Rear Axle < AWD > - Endeavor
GENERAL DESCRIPTION The rear axle has the following features.
The wheel bearing incorporates a unit ball bearing (double-row angular contact
ball bearing) for reduced friction. The rear wheel hub assembly combines the hub, wheel bearing, housing, and
oil seal in a single unit for fewer parts, better durability, improved assembly
precision, and better structural organization. The drive shaft has BJ-DOJ constant velocity joints. ABS rotor for wheel speed detection is press-fitted onto the drive shaft in
vehicles with ABS.

SYMPTOM PROCEDURES INSPECTION PROCEDURE 1: NOISE DURING WHEEL ROTATION {{DRIVE SHAFT}} DIAGNOSIS
STEP 1. 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. Fit the dial gauge as shown in the diagram and move the hub in the axial
direction to measure the play.
Limit: 0.05 mm (0.002 inch)

WHEEL BEARING END PLAY CHECK 1. Remove the caliper assembly, and suspend the caliper assembly with a wire
and remove the brake disc.
2. Fit the dial gauge as shown in the diagram and move the hub in the axial
direction to measure the play.

3. If the play exceeds the limit, replace the wheel bearing (Refer to TRAILING
ARM ).
4. Install the brake disc and caliper assembly, and tighten the caliper assembly
mounting bolts to the specified torque.

3. Hold the rear wheel hub assembly in a vice using wooden blocks.
4. Measure the wheel bearing rotation starting torque by using special tools
MB990326 and MB990685.
Limit: 1.4 N.m (1.03 ft-lb)
5. If the rotation starting torque is not within the limit range when the nut is
tightened to 236 +/- 19 N.m (174 +/- 14 ft-lb), replace the front wheel bearing
assembly. If there is any signs of binding or tight spots when the wheel bearing
turns, replace it.
6. Measure to determine whether the wheel bearing axial play is within the
specified limit or not.
Limit: 0.05 mm (0.002 inch)

Q: Is the ABS sensor in good condition?
YES: Go to Step 6.
NO: Replace the ABS sensor. Then go to Step 16.
STEP 6. Check the wheel bearing for looseness.
DTC C1201 is set: Check the front right wheel bearing (Refer toWHEEL BEARING END PLAY CHECK
).
DTC C1206 is set: Check the front left wheel bearing (Refer to WHEEL BEARING END PLAY CHECK
).
DTC C1211 is set: Check the rear right wheel bearing (Refer to WHEEL BEARING END PLAY CHECK
).
DTC C1216 is set: Check the rear left wheel bearing (Refer to WHEEL BEARING END PLAY CHECK
).
Q: Is the wheel bearing end play within the standard value?
YES: Go to Step 7.
NO (front bearing end play is not within the standard value): Replace
the front hub assembly (Refer to FRONT AXLE HUB ASSEMBLY
, ).
Then go to Step 16.
NO (rear bearing end play is not within the standard value): Replace
the rear hub assembly (Refer to REAR AXLE
). Then go to Step 16.
STEP 7. Check the ABS rotor.
Check the ABS rotor, which DTC code indicates, for foreign material or
deformation.
DTC C1201 is set: Front right ABS sensor DTC C1206 is set: Front left ABS sensor
NOTE: If the wheel bearing is loose, the gap between the ABS
sensor and rotor may become excessive. Check the
wheel bearing, which DTC code indicates, for
looseness.
