>>A<< WHEEL BEARING INSTALLATION
CAUTION
• The magnetic encoder for wheel speed sensor is
installed in the wheel bearing. Install the wheel bearing
so that the encoder is positioned in the direction shown
in the figure.
• When press-fit the wheel bearing, push the outer race.
• After press-fit the wheel bearing, wipe off the extra
grease in order not to remain on the magnetic encoder.
1. Remove grease and foreign material cleanly from the inside
of knuckle bore.
2. Apply the specified grease thinly and evenly to the inside of
knuckle as shown in the figure.
Specified grease: Dowcorning/Molykote BR2 Plus
Amount to use: as required {1.0
− 1.5 g (0.04 −0.05
ounce)}
3. Use special tools MB990883 and MB 990890 to press-fit the
wheel bearing.
4. Remove excessive grease seeped out between knuckle and
wheel bearing outer race after press-fitting the wheel
bearing.
.
>>B<< DUST SHIELD INSTALLATION
Use special tools MB991388 and MB991576 to press-fit the

>>C<< HUB ROTATION STARTING TORQUE
CHECK
1. Set special tools MB991000 and MB991017 as shown in the
figure, tighten the nut to the specified torque, and press-fit
the hub into the knuckle.
Tightening torque: 144
− 176 N⋅m (107 − 129 ft-lb)
2. Rotate the hub to make the bearing well-greased.
3. Use Special tool MB990326 to measure the hub rotation
starting torque.
Limit: 1.5 N
⋅m (13 in-lb)
4. Hub rotation starting torque should be within the limit value,
and there should be no roughness and gritty feeling in
rotation.
.
>>D<< WHEEL BEARING END PLAY CHECK
1. Use special tools MB991000 and MB991017 to measure to
determine whether the wheel bearing end play is within the
specified limit or not.
Limit: 0.05 mm(0.002 inch)
2. If the end play is not within the limit range while the nut is
tightened to specified torque, the bearing, hub and/or
knuckle have probably not been installed correctly. Replace
the bearing and re-install.
Tightening torque: 144
− 176 N⋅m (107 − 129 ft-lb)
INSPECTION
