GENERAL DESCRIPTION

M1261000100370

The front axle consists of front hubs, knuckles, wheel
bearings and drive shafts, and has the following fea-
tures:

• The wheel bearing incorporates double-row

angular contact ball bearing <2.4L>, a unit ball
bearing (double-row angular contact ball bearing)
<3.8L>for reduced friction.

• The front 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.
<3.8L>

• The driveshaft incorporates BJ-TJ type constant

velocity joints <2.4L> and BJ-PTJ type constant
velocity joints <3.8L> with high transmission effi-
ciency 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.<3.8L-RH>

• The dynamic damper is mounted on the LH drive-

shaft <2.4L, 3.8L> and on the RH driveshaft
<2.4L> to reduce differential gear noise.

• ABS rotor for detecting the wheel speed is

press-fitted to the BJ.

TROUBLESHOOTING STRATEGY

M1261005600240

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
front 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

Chart.

4. Verify malfunction is eliminated.
