Disassembly and AssemblyEDS0005T
DISASSEMBLY
1. Set steering knuckle on bench vise at point where strut is
attached. Use a sliding hammer and attachment to remove
wheel hub from steering knuckle.
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. As shown in the figure, use a puller, drift, and bearing replacer 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.

●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 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 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.

FRONT WHEEL HUB AND KNUCKLE
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.

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
