3. WHEEL ARCH HEIGHT
1) Unload cargoes and set vehicle in curb weight
(empty) condition.
2) Then, check wheel arch height of front and rear
suspensions to ensure that they are within speci-
fied values.
3) When wheel arch height is out of standard, visu-
ally inspect following components and replace de-
formed parts.
• Suspension components [Front strut assembly
and rear shock absorber assembly]
• Body parts to which suspensions are installed.
4) When no components are deformed, adjust
wheel arch height by replacing coil spring in the
suspension whose wheel arch height is out of stan-
dard. <Ref. to FS-6, Wheel Alignment.> <Ref. to
RS-8, Wheel Alignment.>
4. WHEEL ALIGNMENT OF FRONT SUS-
PENSION
1) Check alignment of front suspension to ensure
that following items conform to standard values.
• Toe-in
• Camber angle
• Caster angle
• Steering angle
<Ref. to FS-6, Wheel Alignment.>
2) When caster angle does not conform to standard
value, visually inspect following components and
replace deformed parts.
• Suspension components [Strut assembly, cross-
member, transverse link, etc.]
• Body parts to which suspensions are installed.
3) When toe-in and camber are out of standard val-
ue, adjust them so that they conform to respective
service standard.
4) When right-and-left turning angles of tire are out
of standard, adjust to standard value.
5. WHEEL ALIGNMENT OF REAR SUS-
PENSION
1) Check alignment of rear suspension to ensure
that following items are within standard values.
• Toe-in
• Camber angle
• Thrust angle
<Ref. to RS-8, Wheel Alignment.>
2) When camber angle does not conform to stan-
dard value, visually inspect parts listed below. If de-
formation is observed, replace damaged parts.
• Suspension components [Shock absorber, link
F, link R, link UPR, arm R, sub frame, etc.]
• Body parts to which suspensions are installed.
3) When toe-in and thrust angle are out of standard
value, adjust them so that they conform to respec-
tive service standard.

6. OIL LEAKAGE OF STRUT AND SHOCK
ABSORBER
Visually inspect front strut and rear shock absorber
for oil leakage as instructed. Replace front strut and
rear shock absorber if oil leaks excessively.
7. TIGHTNESS OF BOLTS AND NUTS
Check bolts and nuts shown in the figure for loose-
ness. Retighten bolts and nuts to specified torque.
If self-lock nuts and bolts are removed, replace
them with new ones.
Front suspension: <Ref. to FS-3, COMPONENT,
General Description.>
Rear suspension: <Ref. to RS-3, COMPONENT,
General Description.>
8. DAMAGE TO SUSPENSION PARTS
1) Check the following parts and the fastening por-
tion of the vehicle body for deformation or exces-
sive rusting which impairs the suspension. If
necessary, replace damaged parts with new ones.
If minor rust formation, pitting, etc. are noted, re-
move rust and apply remedial anti-corrosion mea-
sures.
• Front suspension
• Transverse link
• Crossmember
• Strut
• Rear suspension
• Sub frame
• Link F
• Link R
• Link UPR
• Arm R
• Shock absorber
• In the district where salt is sprayed to melt snow
on a road in winter and coastal area, check suspen-
sion parts for damage caused by rust every months
or km (miles) specified in "MAINTENANCE
SCHEDULE 2".
