The magnetic encoder collects metallic particles easily,
because it is magnetized. Make sure that the magnetic
encoder should not collect metallic particles. Check
that there is not any trouble prior to reassembling it.
• When installing the front driveshaft, make sure that it
does not contact with the magnetic encoder (integrated
with the inner oil seal) to avoid damage.
• Do not apply the vehicle weight on the wheel bearing
before fully tightening the front driveshaft nut. Other-
wise, the wheel bearing may be broken.

Washer
1. Be sure to install the front driveshaft washer in the illustrated
direction.
2. Using special tool MB990767, tighten the driveshaft nut. At
this time, tighten the nut to the specified lower limit torque so
that the pin hole may align with cotter pin.
Tightening torque: 144
− 176 N⋅ m (107 − 129 ft-lb)
3. If the pin hole does not align with the pin, tighten the
driveshaft nut [less than 176 N
⋅ m (129 ft-lb)] and find the
nearest hole, then fit the cotter pin.

4. Measure the wheel bearing rotation starting torque by using
special tools MB990326 and MB990685.
Limit: 1.4 N
⋅ m (12.39 in-lb)
5. If the rotation starting torque is not within the limit range,
replace the front wheel hub assembly. If there is any signs of
binding or tight spots when the wheel bearing turns, also
replace it.

6. Measure to determine whether the wheel bearing end play is
within the specified limit or not.
Limit: 0.05 mm (0.002 inch)
7. If the play is not within the limit range while the nut is
tightened to 144
− 176 N⋅ m (107 − 129 ft-lb), replace the
front wheel hub assembly.

CAUTION
• The magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that
the magnetic encoder should not collect metallic particles. Check that there is not any trouble
prior to reassembling it.
• When removing and installing the front driveshaft assembly, make sure that the magnetic encoder
(integrated with the inner oil seal) does not contact with surrounding parts to avoid damage.
• When removing and installing the front wheel speed sensor, make sure that the pole piece at the
end does not contact with surrounding parts to avoid damage.
