Place hub on a wood workbench or a block of wood
approx. 6º by 6º to protect the wheel stud ends and
threads.

Install wheel stud, using a hammer.
NOTE: Be sure wheel stud is started squarely and seats
completely.
2. Install the hub unit bearing to the knuckle.
Tighten the bolts to the specified torque.
Hub unit bearing bolt
Torque: 103+10 N´m (10.5 + 1 kg´m)
If there is rust on the bearing and knuckle contact
surfaces, use sandpaper to remove it before installation.
3. Install the ABS sensor connector.
4. Install the disc rotor.
5. Install the brake caliper to the bracket.

Disassembly
1. Move the transfer case lever to the 2WD position.
2. Raise the vehicle with a jack. Support the frame with
chassis stands.
3. Remove the brake caliper from the bracket. Secure
the caliper with a wire that it does not interfare with the
work process.Refer to
Front disc caliper assembly in Section 5C of this
Manual.
4. Remove the disk rotor.
Apply penetrating oil to the bearing and disc rotor contact
surfaces if the surfaces are stuck together because of
rust.
5. Inspect the hub unit bearing. Refer to
inspection
below.

6. Use a dial gauge to measure the bearing axial rattle.
Bearing axial rattle: 0.05 mm max
411R200002If abnormal conditins are discovered during
inspection, go to Step 7. If there are no abnormal
conditions, reassemble the front discrotor and
caliper.
NOTE: Hub, wheel bearing and spindle is integrated to
the hub unit bearing so it must not be disassembled. If it
has abnormal rattle or noize, replace the hub unit bearing.
7. Loosen the caulking around the front drive shaft nuts.
8. Remove the nuts and discard them (they cannot be
reused).
9. Remove the 4 bolts fixing the hub unit bearing to the
knuckle.
Apply penetrating oil to the bearing and knuckle contact
surfaces if the surfaces are stuck together because of
rust.
10. Temporarily install long bolts to 2 of the fixing bolt
holes (the bolts must have the same diameter and
thread width).

11. Strike the long bolts with a hammer to loosen and
remove the hub unit bearing from the knuckle.

Take care not to strike the front drive shaft.

Take care not to drop the bearing.
12. Remove the ABS rotor sensor from the bearing.
13. If necessary, replace the wheel pin in the following
manner.

Place hub on a suitable work surface and remove
wheel studs, as required, using a hammer.
