REMOVAL AND INSTALLATION

Removal Service Points
[A] Caliper Assembly Removal

NOTE: Secure the removed caliper assembly with wire, etc.





[B] Drive Shaft Nut Removal

[C] Lower Arm Ball Joint/Tie Rod End Disconnection





CAUTION:
1. Using the special tool, loosen the tie rod end mounting nut. Only loosen the nut; do not remove it from the ball joint.
2. Support the special tool with a cord, etc. to prevent it from coming off.

Installation Service Point
]A[ Drive Shaft Nut Installation





1. Be sure to install the drive shaft washer in the specified direction.
2. Using the special tool, tighten the drive shaft nut.

CAUTION: Before securely tightening the drive shaft nuts, make sure there is no load on the wheel bearings.

INSPECTION
- Check the front hub and brake disc mounting surfaces for galling and contamination.
- Check the hub for cracks and spline for wear.
- Check the oil seal for damage.
- Check the knuckle for cracks.
- Check for defective bearing.

NOTE: If the meshing of the wheel bearing outer race and the knuckle, or if the wheel bearing inner race and the hub, are loose, replace the bearing or damaged parts.






DISASSEMBLY AND REASSEMBLY

Disassembly Service Points
[A] Hub Removal





CAUTION: When removing the hub, always replace the wheel bearing with a new part.

[B] Wheel Bearing Removal





1. Remove the wheel bearing inner race (outside) from the front hub by using the special tool.

CAUTION: When removing the inner race (outside) from the hub, be careful not to let the hub drop.





2. Install the inner race (outside) that was removed from the hub to the wheel bearing, and then use the special tools to remove the wheel bearing.

Reassembly Service Points
]A[ Wheel Bearing Installation





Press-in the bearing by using the special tools.

CAUTION: Press the outer race when pressing-in the wheel bearing.

]B[ Wheel Bearing Breakaway Torque Check/Hub End Play Check
1. Use the special tool to mount the hub onto the knuckle.





2. Tighten the nut of the special tool to 177 - 275 Nm (130 - 203 ft. lbs.).
3. Rotate the hub in order to seat the bearing.





4. Measure the wheel bearing breakaway torque (hub breakaway torque) by using the special tools.
Limit: 1.8 Nm (15.62 inch lbs.) or less
5. The breakaway torque must be within the limit and, in addition, the bearing must not feel rough when rotated.





6. Measure to determine whether the end play of the hub is within the specified limit or not.
Limit: 0.05 mm (0.002 inch)
7. If the breakaway torque and hub end play are not within the limit range while the nut is tightened to 177 - 275 Nm (130 - 203 ft. lbs.), the bearing, hub and/or knuckle have probably not been installed correctly. Remove the bearing and re-install.

INSPECTION
Check the knuckle inner surface for galling and cracks.
