2004 MITSUBISHI ENDEAVOR Wheel hub assembly

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 to WHEEL 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 front right wheel bearing (WHEEL BEARING END PLAY CHECK
). < AWD > Refer to WHEEL
BEARING END PLAY CHECK
).
DTC C1216 is set: Check the rear left wheel bearing (< FWD > Refer to
WHEEL BEARING END PLAY CHECK
). < AWD > Refer to
WHEEL BEARING END PLAY CHECK ).
Q: Is the wheel bearing end play is not 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 < FWD >):
Replace the rear hub assembly (Refer to REAR AXLE HUB
ASSEMBLY
). Then go to Step 16 .
NO (rear bearing end play is not within the standard value < AWD
>): Replace the rear hub assembly (Refer to , REAR AXLE HUB
ASSEMBLY ). Then
go to Ste
p 16. 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.

2004 DRIVELINE/AXLES
Front Axle - Endeavor
GENERAL DESCRIPTION The front axle consists of front hubs, knuckles, wheel bearings and drive shafts, and
has the following features:
The wheel bearing incorporates a unit ball bearing (double-row angular contact
ball bearing) for reduced friction. The front 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 driveshaft incorporates BJ-PTJ type constant velocity joints< FWD>, BJ-
DOJ < AWD-LH>and BJ-TJ< AWD-RH> with high transmission efficiency
for low vibration and noise. Due to the use of the inner shaft and bracket assembly, the right and left drive
shafts are approximately the same in length. This reduces noise, vibration and
torque steer.< FWD> ABS rotor for detecting the wheel speeds is press-fitted to the rear hub in
vehicles with ABS.

SYMPTOM PROCEDURES INSPECTION PROCEDURE 1: Noise During Wheel Rotation DIAGNOSIS
STEP 1. Check the wheel bearing end play.
1. Remove the caliper assembly and suspend it with a wire.
2. Remove the brake disc from the front hub.
3. Attach a dial gauge as shown in the illustration, and then measure the end
play while moving the hub in the axial direction.
Limit: 0.05 mm (0.002 inch)
Q: Is the wheel bearing end play within the limit?
YES: Go to step 2.
NO: Replace the part, then go to Step
5.

NO: There is no action to be taken.
STEP 5. Retest the system.
Q: Is the abnormal noise eliminated?
NO: Repeat to Step 1 .
YES: The procedure is complete.
INSPECTION PROCEDURE 2: Noise Due To Excessive Play Of Wheel In Turning Direction DIAGNOSIS
STEP 1. Check for play in the inner shaft and side gear serration, the
drive shaft and side gear serration, or the drive shaft and front hub
serration.
Q: Is the play found?
YES: Replace the part. Then go to Step 2.
NO: The procedure is complete.
STEP 2. Retest the system.
Q: Is the abnormal noise eliminated?
NO: Repeat to Step 1.
