FRONT AXLE HUB ASSEMBLY

REMOVAL AND INSTALLATION

M1261001700450

CAUTION

• Do not disassemble the front wheel hub assembly.
• The vehicle speed detection magnetic encoder collects any metallic particle easily, because it is

magnetised. Make sure that the magnetic encoder should not collect any metallic particle. Check
that there is not any trouble prior to reassembling it.

• When the front wheel hub assembly is removed and installed, make sure that the vehicle speed

detection magnetic encoder does not contact with surrounding parts to avoid damage.

• When the front wheel speed sensor is removed and installed, make sure that its pole piece does

not contact with surrounding parts to avoid damage.

Post-installation Operation
• Check the dust cover for cracks or damage by pushing it

with your finger.

REMOVAL SERVICE POINTS
<<A>> DRIVE SHAFT NUT REMOVAL

CAUTION

Do not apply pressure to wheel bearing by the
vehicle weight to avoid possible damage when
drive shaft nut is loosened.

Use special tool end yoke holder (MB990767) to fix
the hub and remove the drive shaft nut.

<<B>> CALIPER ASSEMBLY REMOVAL

Secure the removed caliper assembly with wire, etc.

<<C>> BRAKE DISC REMOVAL

If the brake disc is seized, install a M8 x 1.25 bolts as
shown, and remove the disc by tightening the bolts
evenly and gradually.

<<D>> SELF-LOCKING NUT (TIE ROD
END CONNECTION) REMOVAL

CAUTION

• Do not remove the nut from ball joint. Loosen

it and use the special tool to avoid possible
damage to ball joint threads.

• Hang the special tool with cord to prevent it

from falling.

1. Install special tool ball joint remover (MB991897)

as shown in the figure.

2. Turn the bolt and knob as necessary to make the

jaws of special tool parallel, tighten the bolt by
hand and confirm that the jaws are still parallel.
NOTE: When adjusting the jaws in parallel, make
sure the knob is in the position shown in the
figure.

3. Tighten the bolt with a wrench to disconnect the

tie rod end.

<<E>> DRIVE SHAFT REMOVAL

CAUTION

•

The vehicle speed detection magnetic encoder

collects any metallic particle easily, because it
is magnetised. Make sure that the magnetic
encoder does not collect any metallic particle.

• When the drive shaft is removed, make sure

that it does not contact with the vehicle speed
detection magnetic encoder to avoid damage.

Use the following special tools to push out the drive
shaft from the hub.

• Puller shaft (MB990242)

• Puller bar (MB990244)

• Puller body (MB991354)

• End yoke holder (MB990767)

INSTALLATION SERVICE POINT
>>A<< WASHER/ DRIVE SHAFT NUT
INSTALLATION

CAUTION

• The vehicle speed detection magnetic

encoder collects any metallic particle easily,
because it is magnetised. Make sure that the
magnetic encoder should not collect any
metallic particle. Check that there is not any
trouble prior to reassembling it.

• When the drive shaft is installed, make sure

that it does not contact with the vehicle speed
detection magnetic encoder to avoid damage.

• Before securely tightening the drive shaft

nuts, make sure there is no load on the wheel
bearings. Otherwise the wheel bearings will
be damaged.

1. Be sure to install the drive shaft washer in the

specified direction.

2. Using special tool end yoke holder (MB990767),

tighten the drive shaft nut to the specified torque.

Tightening torque: 245

± 29 N⋅m

• Spacer (MB991000)

Tightening torque: 245

± 29 N⋅m

2. Hold front wheel hub assembly in a vice, using

wooden blocks.

3. Rotate the hub in order to seat the bearing.

4. Measure the wheel bearing rotation starting

torque by using the following special tools.

• Preload socket (MB990326)

• Torque wrench (MB990685)

Limit: 2.1 N

⋅m

5. If the rotation starting torque is not within the limit

when the nut is tightened to 245

± 29 N⋅m, replace

the front wheel hub assembly. If there is any signs
of binding or tight spots when the wheel bearing
turns, replace it too.

6. Use the special tool to measure to determine

whether the wheel bearing axial play is within the
specified limit or not.

Limit: 0.05 mm

7. If the play exceeds the limit when the nut is

tightened to 245

± 29 N⋅m, replace the front wheel

hub assembly.
