FRONT SUSPENSION PARTSNJSU0006Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspension nuts and bolts to the speci-
fied torque.
Tightening torque:
Refer to ªFRONT SUSPENSIONº, SU-5.
SFA392B
+Check strut (shock absorber) for oil leakage or other damage.
+Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
If ball joint dust cover is cracked or damaged, replace trans-
verse link.
SFA818AA
+Check spring height from top of wheelarch to the ground.
a) Vehicle must be unladen*, parked on a level surface, and tires
checked for proper inflation and wear (tread wear indicator
must not be showing).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
b) Bounce vehicle up and down several times before measuring.
Standard height: Refer to SDS, SU-15.
c) Spring height is not adjustable. If out of specification, check for
worn springs or suspension parts.
SSU031
+Check suspension ball joint end play.
a) Jack up front of vehicle and set the stands.
b) Clamp dial indicator onto transverse link and place indicator tip
on lower edge of brake caliper.
c) Make sure front wheels are straight and brake pedal is
depressed.
d) Place a pry bar between transverse link and inner rim of road
wheel.
e) While raising and releasing pry bar, observe maximum dial
indicator value.
Vertical end play: 0 mm (0 in)
f) If ball joint movement is beyond specifications, remove and
replace it.

PurposeNJBR0082The ABS consists of electronic and hydraulic components. It allows for control of braking force so that lock-
ing of the wheels can be avoided.
The ABS:
1) Ensures proper tracking performance through steering wheel operation.
2) Enables obstacles to be avoided through steering wheel operation.
3) Ensures vehicle stability by preventing flat spins.
ABS (Anti-Lock Brake System) OperationNJBR0083+When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
+The Anti-Lock Brake System (ABS) has self-test capabilities. The system turns on the ABS warning lamp
for 1 second after turning the ignition switch ON. The system performs another test the first time the vehicle
reaches 6 km/h (4 MPH). A mechanical noise may be heard as the ABS performs a self-test. This is a
normal part of the self-test feature. If a malfunction is found during this check, the ABS warning lamp will
come on.
+During ABS operation, a mechanical noise may be heard. This is a normal condition.
