2. Check the brake disc for scoring and damage.
3. Check the knuckle for cracks.
4. Check the bearing for cracks or damage.

REASSEMBLY
1. Apply multipurpose grease to the contacting surface of the knuckle hub and bearing thinly.





2. Using the Special Tool (09495-33100), press-in the bearing to the knuckle.

NOTE:
^ Press-in the outer race of the wheel bearing to prevent damage to the bearing assembly
^ When installing a bearing assembly, always use a new one.

Specified torque Nm (kg~cm, flab): 200 ± 260 (2000 ± 2600, 159 ± 192)
8. Rotate the hub several times to seat the bearing.





9. Measure the hub bearing starting torque.
Hub bearing starting torque [Limit]: 1.8 Nm (18 kg cm, 16 inch lbs.) or less





10. If the starting torque is O Nm (O inch lbs.), measure the hub bearing axial play.
11. If the hub axial play exceeds the limit while the nut is tightened to 200 - 260 Nm (2000 - 2600 kgf-cm, 159 - 192 ft. lbs.), the bearing, hub and knuckle are not installed correctly. Repeat the disassembly and assembly procedure.
