FRONT WHEEL HUB AND KNUCKLEPFP:40202
On-Vehicle InspectionEDS0005R
Inspect to check that there is no excessive play, cracking, wear, o r
other damage to front axle.
●Turn front wheels (left/right) and check the play.
●Check that no nails or other foreign objects are embedded.
●Retighten all axle nuts and bolts to the specified torque.
FRONT WHEEL BEARINGS
With the vehicle raised, inspect the following.
●Move wheel hub in the axial direction by hand. Check that there is no looseness of front wheel bearings.
●Rotate wheel hub and check that there is no unusual noise or other irregular conditions. If there are any
irregular conditions, replace the wheel bearing.
Removal and InstallationEDS0005S
REMOVAL
1. Remove tire. Remove brake hose lock plate from strut.
2. Remove brake caliper from steering knuckle. Hang it in a place where it will not interfere with work.
CAUTION:
Avoid depressing the brake pedal with brake caliper removed.
3. Remove ABS wheel speed sensor from steering knuckle.
CAUTION:
Do not pull on ABS wheel speed sensor harness.

4. Use a drift and a press to install wheel hub.
5. As shown in the figure, apply a load of 49,030 N (5,000
kg,11,025 lb). Rotate in forward and reverse directions 10 times
each to ensure a good fit.
6. At a rotation speed of 8 - 12 rpm, place a spring balance at the point where strut is joined (upper-side bolt
hole). Measure rotation torque. Refer to FAX-17, "
Wheel Bearing" .
NOTE:
If a load of 49,030 N (5,000 kg, 11,025 lb) cannot be applied, carry out the following actions.
●Assemble drive shaft and tighten wheel hub lock nuts to specified torque. Then rotate in forward and
reverse direction 10 times each to ensure a good fit.
●At a rotation speed of 8 - 12 rpm, place a spring balance on hub bolt to measure torque.
SDIA0592E
Rotation torque : 1.645 N·m (0.168 kg-m, 15 in-lb) or less
Spring balance reading : 10.6 N (1.1 kg, 2.4 lb) or less
Rotation torque : 2.125 N·m (0.217 kg-m, 19 in-lb) or less
Spring balance reading : 37.2 N (3.8 kg, 8.4 lb) or less

FRONT DRIVE SHAFT
●When the drive shafts listed below have been removed, check that a circular clip is attached to the end.
×: Applicable
–: Not applicable
●Remove installation bolt from right-side drive shaft support bearing bracket. Then remove bracket from
engine.
●Remove installation bolt from right-side drive shaft and remove drive shaft from side shaft.
INSPECTION AFTER REMOVAL
●Move joint in up/down, left/right, and axial directions. Check for
motion that is not smooth and for significant looseness.
●Check for cracking and damage of boots, and for grease leak-
age.
INSTALLATION
●Install support bearing bracket onto engine and tighten installation bolts to specified torque.
●Install drive shaft to side shaft and tighten installation bolts to specified torque.
1. In order to prevent damage to differential side oil seal, first fit a
protector onto oil seal before inserting drive shaft. Slide drive
shaft slide joint and tap with a hammer to install securely.
CAUTION:
Be sure to check that circular clip is securely fastened.
2. Insert drive shaft into steering knuckle. Install lock nut and then
temporarily tighten lock nuts.
3. Install installation bolt for steering knuckle and strut.
4. Use lock plate to fix brake hose to strut.
5. Install tie rod to steering knuckle.
6. Install ABS wheel speed sensor.
7. Tighten lock nuts to specified torque.
8. Install cotter pin.
CAUTION:
Discard the old cotter pin; replace with a new one.

2. Remove wheel hub lock nuts.
CAUTION:
Discard the old hub lock nuts; replace with new ones.
3. Remove brake caliper from axle housing and hang it up some-
where.
CAUTION:
Avoid depressing the brake pedal while the brake caliper is
removed.
4. Remove disc rotor and parking brake assembly from back plate
and axle housing.
5. Remove ABS wheel speed sensor from axle housing.
6. Remove axle housing from strut.
7. Remove nut and bolt from axle housing side of radius rod.
8. Remove nuts and bolts from axle housing sides of front and rear parallel links. Remove axle housing from
vehicle.
INSTALLATION
●Refer to component parts drawing for tightening torque. For installation, follow removal procedure in
reverse order.
Disassembly and AssemblyEDS00067
DISASSEMBLY
1. Set axle housing on bench vise. As shown in the figure, use
attachment and sliding hammer to remove wheel hub from axle
housing.
CAUTION:
When placing onto bench vise, be careful not to damage
strut mounting surface of steering knuckle. Use an alumi-
num plate or another suitable tool.
2. Use a bearing replace, puller, and adapter to remove inner race
of outer-wheel bearing from wheel hub.
3. Remove back plate installation bolt and anchor block. Remove
back plate from axle housing. Refer to PB-5, "
Components"
4. Use a flat-bladed screwdriver or similar tool to remove snap ring.
5. Use a drift to remove wheel bearing from axle housing.

5. After completing step 4, apply an additional load of 34,300 -
49,000 N (3,500 - 5,000 kg, 7,718 - 11,025 lb). Rotate axle hous-
ing in forward and reverse directions 10 times each to ensure a
good fit.
