FRONT WHEEL HUB AND KNUCKLE

Removal and Installation


REMOVAL

Wheel Hub and Bearing Assembly
1.Remove tires with power tool.
2.Remove wheel sensor from steering knuckle. Refer to "FRONT WHEEL SENSOR : Exploded View" ABS (without VDC), "FRONT WHEEL SENSOR : Exploded View" VDC/TCS/ABS (with VDC).

CAUTION:
Never pull on wheel sensor harness.
3.Remove lock plate from strut assembly. Refer to "FRONT : Exploded View" Exploded View.
4.Remove torque member mounting bolts with power tool. Hang torque member not to interfere with work.
Refer to "BRAKE CALIPER ASSEMBLY : Exploded View" Exploded View.

CAUTION:
Never depress brake pedal while brake caliper is removed.
5.Remove disc rotor. Refer to "BRAKE CALIPER ASSEMBLY : Removal and Installation" Removal And Installation.

CAUTION:
- Put matching marks on the wheel hub and bearing assembly and the disc rotor before removing the disc rotor.
- Never drop disc rotor.
6.Remove cotter pin and adjusting cap, and then loosen wheel hub lock nut with power tool.





7.Patch wheel hub lock nut with a piece of wood. Hammer the wood to disengage wheel hub and bearing assembly from drive shaft. Remove the wheel hub lock nut.

CAUTION:
- Never place drive shaft joint at an extreme angle. Also be careful not to overextend slide joint.
- Never allow drive shaft to hang down without support for housing (or joint sub-assembly), shaft and the other parts.
NOTE:
Use suitable puller, if wheel hub and bearing assembly and drive shaft cannot be separated even after performing the above procedure.
8.Remove wheel hub and bearing assembly.





9.Remove hub bolts (1) from wheel hub and bearing assembly, using the ball joint remover (A) (commercial service tool).

CAUTION:
- Remove hub bolt only when necessary.
- Never hammer the hub bolt to avoid impact to the wheel hub and bearing assembly.
- Pull out the hub bolt in a direction perpendicular to the wheel hub and bearing assembly.
Steering Knuckle
1.Remove wheel hub and bearing assembly, and then remove splash guard.
2.Remove transverse link from steering knuckle.
3.Remove steering knuckle from strut assembly.





4.Loosen the nut (black arrow) of steering outer socket.
5.Remove steering outer socket (1) from steering knuckle (2)
using the ball joint remover so as not to damage ball joint boot (3).

CAUTION:
Temporarily tighten the nut to prevent damage to threads and to prevent the ball joint remover from suddenly coming off.
6.Remove steering knuckle from vehicle.

INSTALLATION

Note the following, and install in the reverse order of the removal.





- Place a washer (A) as shown in the figure to install the hub bolts (1) by using the tightening force of the nut (B).

CAUTION:
- Check that there is no clearance between wheel hub and bearing assembly, and hub bolt.
- Never reuse hub bolt.
- Never reuse steering knuckle and transverse link fixing nut.
- Clean the matching surface of wheel hub lock nut and wheel hub and bearing assembly.

CAUTION:
Never apply lubricating oil to these matching surface.





- Clean the matching surface of drive shaft, wheel hub and bearing assembly. And then apply paste [service parts (440037S000)] to surface (A) of joint sub-assembly of drive shaft.

CAUTION:
Apply paste to cover entire flat surface of joint sub-assembly of drive shaft.

Amount paste: 1.0 - 3.0 g (0.04 - 0.10 oz)

- Use the following torque range for tightening the wheel hub lock nut.






CAUTION:
- Since the drive shaft is assembled by press-fitting, use the tightening torque range for the wheel hub lock nut.
- Be sure to use torque wrench to tighten the wheel hub lock nut. Never use a power tool.
- Never reuse wheel hub lock nut.
NOTE:
Wheel hub lock nut tightening torque does not over torque for avoiding axle noise, and does not less than torque for avoiding looseness.
- Align the matching marks that have been made during removal when reusing the disc rotor.





- When installing a cotter pin (1) and adjusting cap (2), securely bend the basal portion to prevent rattles.

CAUTION:
Never reuse cotter pin.
- Perform the final tightening of each of parts under unladen conditions, which were removed when removing wheel hub and bearing assembly and steering knuckle.
