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.

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

DRIVE SHAFT ASSEMBLY
FRONT AXLE26-16
CAUTION
•Do not pull on the drive shaft; doing so will
damage the TJ; be sure to use the pry bar.
•When pulling the drive shaft out from the
transmission, be careful that the spline part of
the drive shaft does not damage the oil seal.
3. Insert a pry bar between the transmission case
and the drive shaft, and then pry and remove the
drive shaft from the transmission.4. Use special tool plug (MB991460) to prevent the
entry of foreign material into the transmission
case.
CAUTION
Do not apply pressure to the wheel bearing by
the vehicle weight to avoid possible damage
when the drive shaft is removed. If, however,
vehicle weight must be applied to the bearing in
moving the vehicle, temporarily secure the wheel
bearing by using the following special tools.
