1. Remove the caliper assembly and suspend it with
a wire.
2. Remove the brake disc from the front hub.
3. Attach a dial gauge as shown in the illustration,
and then measure the axial play while moving the
hub in the axial direction.
Limit: 0.05 mm
4. If axial play exceeds the limit, disassemble the
front hub assembly and check the parts.
5. Install the brake disc, caliper assembly and
tighten the caliper assembly mounting bolts to the
specified torque 100 ± 10 N⋅m.
HUB BOLT REPLACEMENTM1261001000291

>>A<< STABILIZER
RUBBER/SELF-LOCKING NUT
(STABILIZER BAR CONNECTION)
INSTALLATION
Install the stabilizer rubber and collar as shown in the
figure, and tighten the self-locking nut so that the
protruding length of the stabilizer bar mounting bolt
protruding part meets its standard value (A).
Standard value (A): 22 ± 1.5 mm
>>B<< WASHER/ DRIVE SHAFT NUT
INSTALLATION
CAUTION
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.

REASSEMBLY SERVICE POINTS
>>A<< WHEEL BEARING INSTALLATION
1. Fill the wheel bearing with multipurpose grease.
2. Apply a thin coating of multipurpose grease to the
knuckle and bearing contact surfaces.
CAUTION
Press the outer race when pressing-in the wheel
bearing. Otherwise the wheel bearing will be
damaged.
3. Press-in the bearing by using the following special
tools.
•Rear suspension bushing arbor (MB990883)
•Rear suspension bushing base (MB990890)
>>B<< HUB STARTING TORQUE CHECK
1. Tighten the following special tools to the specified
torque, and then press-in the hub into the knuckle.
•Front hub remover and installer (MB991017)
•Spacer (MB991000)
2. Rotate the hub in order to seat the bearing.3. Measure the hub starting torque by using the
following special tools.
•Torque wrench (MB990685)
•Preload socket (MB990326)
Limit: 1.8 N⋅m
4. The starting torque must be within the limit and
the hub rotation must be smooth.
>>C<< WHEEL BEARING AXIAL PLAY
CHECK
1. Measure to determine whether the wheel bearing
axial play is within the limit or not by using the
following special tools.
•Front hub remover and installer (MB991017)
•Spacer (MB991000)
Limit: 0.05 mm
2. If the play is not within the limit range while the nut
is tightened to 245 ± 29 N⋅m, the bearing, hub
and/or knuckle have probably not been installed
correctly. Replace the bearing and re-install.
INSPECTIONM1261002000078
•Check the front hub and brake disc mounting
surfaces for galling and contamination.
•Check the knuckle inner surface for galling and
