5. Replace the gasket, and tighten to the specified
torque.
Tightening torque:
<4G1> 21 ± 4 N⋅m
<4G6> 20 ± 2 N⋅m
EGR PORT VACUUM CHECK <4G1>M1173002900167
1. Disconnect the vacuum hose (Green stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (Green stripe).
3. Start the engine and check that, after raising the
engine speed by racing the engine, purge vacuum
raises according to engine speed.
NOTE: If there is a problem with change in
vacuum, the throttle body purge port may be
clogged and require cleaning.
EGR PORT VACUUM CHECK <4G6>M1173002900156
1. Disconnect the vacuum hose (White stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (White stripe).
3. Start the engine.
4. Check that a fairly constant negative is generated
regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.
EGR CONTROL SOLENOID VALVE
CHECK <4G1>
M1173003100238
NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid
valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the
solenoid valve (refer to the illustration at left).
4. Check air tightness by applying a vacuum with
voltage applied directly from the battery to the
EGR control solenoid valve and without applying
voltage.

WHEEL BEARING AXIAL PLAY CHECKM1261000900224
1. Remove the caliper assembly and suspend it with
a wire.
2. Remove the brake disc from the front hub.
3. Attach a dial gauge as shown in the illustration,
and then measure the axial play while moving the
hub in the axial direction.
Limit: 0.05 mm
4. If axial play exceeds the limit, disassemble the
front hub assembly and check the parts.
5. Install the brake disc, caliper assembly and
tighten the caliper assembly mounting bolts to the
specified torque 100 ± 10 N⋅m.
HUB BOLT REPLACEMENTM1261001000291
1. Remove the caliper assembly and suspend it with
wire so that it does not fall.
2. Remove the brake disc.3. Use special tool hub bolt remover (MB991618) to
remove the hub bolts.
4. Install the plain washer to the new hub bolt, and
install the bolt with a nut while holding the hub
with special tool end yoke holder (MB990767).
