Front Hub/Knuckle

FRONT AXLE

FRONT HUB / KNUCKLE

COMPONENTS:

REMOVAL





1. Raise the vehicle and remove the front wheel.





2. Remove the wheel speed sensor (A) from the knuckle.








3. Remove the caliper assembly by loosening the bolts (A), and then suspend it with wire.





4. Remove the split pin (B), castle nut (A) and washer from the front hub assembly.





5. Remove the ball joint assembly mounting bolt (A) from the knuckle.
6. Remove the tie rod end split pin and castle nut.
Tightening torque Nm (kgf.m, ft. lbs.): 24 - 34 (2.4 - 3.4, 17 - 25)





7. Disconnect the tie rod end (A) from the knuckle using the SST (09568 - 4A000).





8. Loosen the screws and remove the brake disc (A) from the front hub assembly.





9. Remove the strut assembly mounting bolts (A) and nuts.
10. Remove the hub and knuckle as an assembly.

CAUTION: Be careful not to damage the boot and tone wheel.

DISASSEMBLY





1. Remove the snap ring (A).





2. Remove the hub from the knuckle assembly using the SST (09545-34100).





3. Remove the wheel bearing inner race from the hub using the SST (09432-11000, 09545-34100).





4. Remove the wheel bearing outer race from the hub using the SST (09216-21600, 09216-21100).

INSPECTION
Wheel Bearing Check





1. Raise the vehicle until the front tires are off the floor.
- Make sure the wheels are in a straight forward position.

NOTE: Make sure the wheel rotates freely and that the brake pads are retraced sufficiently to allow free movement of the tire and wheel assembly.
Spin the tire by hand to check the wheel bearings for roughness.





2. Grip each front tire at the top and bottom and move the wheel inward and outward while lifting the weight of the tire off the front wheel bearings.
3. If the tire and wheel (hub) is loose on the spindle, does not rotate freely, or has a rough feeling when spun, carry out one of the following.
On vehicles with inner and outer bearings, inspect the bearings and races for wear or damage. Adjust or install new bearing and races as necessary
4. Check the hub for cracks and the splines for wear.
5. Check the brake disc for scoring and damage.
6. Check the knuckle for cracks.
7. Check the bearing for cracks or damage.

REASSEMBLY
1. Apply the multi-purpose grease to the contacting surface of the knuckle and wheel bearing thinly.





2. Press-in the wheel bearing to the knuckle using the SST (09216-21100).

CAUTION:
^ Do not against the inner race of the wheel bearing because that can cause damage to the bearing assembly.
^ Always use a now wheel bearing assembly.

3. Install the snap ring into the groove the knuckle.
4. Press-in the hub to the knuckle using the SST (09454-21100).

CAUTION:
^ Do not against the outer race of the wheel bearing because that can cause damage to the bearing assembly.





5. Tighten the hub to the knuckle with the SST (09517-21500).
6. Rotate the hub to seat the wheel bearing.





7. Measure the wheel bearing starting torque.
8. Measure the hub run-out by using a dial gauge.
Run-out: 0.04 mm (0.00157 inch)
9. Remove the SST (09517-21500).

INSTALLATION





1. Installation is the reverse of removal.

CAUTION: The washer (B) should be assembled with convex surface outward when installing the castle (A) nut and split pin (C).
