ASSEMBLY SERVICE POINTS

.

>>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 
knuckle into the dust shield.
NOTE: Use the bolts (M12) to align the caliper mounting holes.

>>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

M1261002000142

• Check the front hub and brake disc mounting surfaces for 

galling and contamination.

• Check the knuckle inner surface for galling and cracks.
