Suspension
PERIODIC MAINTENANCE SERVICES
17.Suspension
A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out
along the shaft. If relative movement is observed
between the brake disc cover (A) and end of front
arm (D), ball joint (C) may be excessively worn.
3) Grasp the end of front arm and move it up and
down. Relative movement (A) between the housing
(D) and front arm (C) boss indicates ball joint (B)
may be excessively worn.
4) If relative movement is observed in the step 2),
3), remove and inspect the ball joint. If the free play
exceeds standard value, replace the ball joint.
5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the front arm.
(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with a
new ball joint.
NOTE:
When the front arm ball joint has been removed or
replaced, check the toe-in of front wheel. If the front
wheel toe-in is not at specified value, adjust the
toe-in.
2. FRONT, REAR SUSPENSION BUSHING
Apply pressure with tire lever etc, and inspect the
bushing for wear or crack. Replace the bushings
and the arm assembly or link assembly if there is
wear or there are cracks.
3. WHEEL ARCH HEIGHT
1) Unload the cargo and set the vehicle in curb
weight (empty) condition.
2) Check the wheel arch height of the front and rear
suspensions to ensure that they are within speci-
fied values.
3) When the wheel arch height is out of standard,
visually inspect following components and replace
deformed parts.
•Suspension components [Front strut assembly
and rear shock absorber assembly]
•Parts connecting suspension and body
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.
