Rear AxleandRear Suspension Parts

Check axleandsuspension partsforexcessive play,wear or
damage.
• Shake eachrearwheel tocheck forexcessive play.
• Retighten allnuts andbolts tothe specified torque.

Tightening torque:
Refer toREAR SUSPENSION (RA-8).

• Check shockabsorber for
oil
leakage orother damage.

Rear Wheel Bearing

• Check axialendplay.

Axial endplay:
0.05 mm(0.0020 in)orless

• Check thatwheel hubbearings operatesmoothly.
• Check tightening torqueofwheel bearing locknut.

(OJ:
186 •255 N.m (19-26 kg-m, 137•188 ft-Ib)

• Replace wheelbearing assembly ifthere isaxial endplay
or wheel bearing doesnotturn smoothly. RefertoREAR

CAMBER
Camber ispreset atfactory andcannot beadjusted.
Camber: Refer toSOS (RA-12).

• Ifthe camber isnot within specification, inspectandreplace
any damaged orworn rearsuspension parts.

TOE-IN
Toe-in ispreset atfactory andcannot beadjusted.
Measure toe-inusingfollowing procedure. Ifout of
specification, inspectandreplace anydamaged orworn rear
suspension parts.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce rearofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16
ft).

3. Putamark onbase lineofthe tread (rearside) ofboth tires at
the same height ofhub center. Thismark isameasuring point.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees (1/2turn), try
the above procedure againfromthebeginning. Neverpush
vehicle backward.

6. Measure distance"B"(front side).
