On-Vehicle InspectionEDS0005R
Inspect to check that there is no excessive play, cracking, wear, or
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 tyre. 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. Refer
to BR-27, "
FRONT DISC BRAKE" .
CAUTION:
Avoid depressing the brake pedal with brake caliper removed.
3. Remove wheel sensor from steering knuckle. Refer to BRC-116, "
WHEEL SENSORS" .
CAUTION:
Do not pull on wheel sensor harness.

4. Remove cotter pin. Use a hub lock nut wrench to remove lock
nut from drive shaft.
5. Remove disc rotor from wheel hub.
6. Remove cotter pin. Use a ball joint remover to remove tie rod
from steering knuckle.
CAUTION:
When using a ball joint remover, install nuts temporarily.
7. Remove steering knuckle from strut.
8. Remove drive shaft from steering knuckle.
9. Remove cotter pin. Use a ball joint remover to remove trans-
verse link from steering knuckle.
CAUTION:
When using a ball joint remover, install nuts temporarily.
INSPECTON AFTER REMOVAL
Check for deformity, cracks and damage on each parts, replace if necessary.
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of transverse link ball joint. Refer to FSU-10,
"INSPECTION AFTER REMOVAL" .
INSTALLATION
Refer to FAX-7, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.
Disassembly and AssemblyEDS0005T
DISASSEMBLY
1. Set steering knuckle on bench vise at point where strut is
attached. Use a sliding hammer (SST) and attachment (SST) to
remove wheel hub and bearing assembly from steering knuckle.
CAUTION:
When placing onto vise, be careful not to damage strut
mounting surface of steering knuckle. Use an aluminum
plate or another suitable tool.
2. As shown in the figure, use a puller (suitable tool), drift (SST),
and bearing replacer (SST) to remove inner race of outer wheel
bearing from wheel hub.
3. Use a flat-bladed screwdriver or similar tool to remove snap ring.
CAUTION:
Be careful not to scratch the steering knuckle.
4. Fix steering knuckle to bench vise. Use a flat-bladed screwdriver
and hammer to remove splash guard from steering knuckle.

INSPECTION AFTER DISASSEMBLY
Wheel Hub
Check wheel bearings for damage, seizure, and corrosion. Also check wheel hubs for cracks (using a die
test or other method). Replace if any irregular conditions are found.
Steering Knuckle
Check steering knuckle for deformation, cracks, and other damage. Replace if any irregular conditions are
found.
Snap Ring
Check snap ring for wear or other damage. Replace if any irregular conditions are found.
ASSEMBLY
1. Use a drift (SST) to install splash guard onto steering knuckle.
CAUTION:
Discard the old splash guard; replace with a new one.
Install splash guard in position shown in the figure.
2. Use a drift (SST) and a press to press-fit wheel bearing onto
steering knuckle.
CAUTION:
Discard the old wheel bearing; replace with a new one.
3. Install snap ring onto steering knuckle.

4. Use a drift (SST) and a press to install wheel hub.
5. As shown in the figure, apply a load of 34,324 – 49,033 N
(3500 – 5,000 kg, 7718 – 11,025 lb). Rotate in forward and
reverse directions 10 times each to ensure a good fit.
6. At a rotation speed of 10±2 rpm, place a spring balance at the
point where strut is joined (upper-side bolt hole). Measure rotat-
ing torque. Refer to FA X - 1 9 , "
Wheel Bearing" .
NOTE:
If a load of 34,300 – 49,033 N (3,500 – 5,000 kg, 7718 – 11,025 lb) cannot be applied, carry out the fol-
lowing 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 10±2 rpm, place a spring balance on hub bolt to measure torque. Rotating torque : 1.645 N·m (0.17 kg-m, 15 in-lb) or
less
Spring balance
reading: 10.6 N (1.1 kg, 2.4 lb) or less
Rotation torque : 2.215 N·m (0.22 kg-m, 19 in-lb) or less
Spring balance reading : 37.2 N (3.8 kg, 8.4 lb) or less
