FRONT AXLE PARTSNJAX0005Check 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 SU-9, ªFRONT SUSPENSIONº.
SFA805B
FRONT WHEEL BEARINGNJAX0006+Check that wheel bearings operate smoothly.
+Check axial end play.
Axial end play:
0.05 mm (0.0020 in)
If out of specification or wheel bearing does not turn smoothly,
replace wheel bearing assembly.
Refer to ªWheel Hub and Knuckleº, ªFRONT AXLEº, AX-5.

Precautions
PRECAUTIONSNJAX0022+When installing each rubber part, final tightening must be
carried out under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+Use flare nut wrench when removing or installing brake
tubes.
+After installing removed suspension parts, check wheel
alignment.
+Do not jack up at the trailing arm and lateral link.
+Always torque brake lines when installing.

REMOVALNJAX0029CAUTION:
+Before removing the rear wheel hub assembly, disconnect
the ABS wheel sensor from the assembly. Then move it
away from the hub assembly. Failure to do so may result
in damage to the sensor wires and the sensor becoming
inoperative.
+Wheel hub bearing does not require maintenance. If any of
the following symptoms are noted, replace wheel hub
bearing assembly.
1) Growling noise is emitted from wheel hub bearing dur-
ing operation.
2) Wheel hub bearing drags or turns roughly. This occurs
when turning hub by hand after bearing lock nut is tight-
ened to specified torque.

Precautions
PRECAUTIONSNJSU0001+When installing rubber parts, final tightening must be car-
ried out under unladen condition* with tires on ground.
Oil will shorten the life of rubber bushes. Be sure to wipe
off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Use flare nut wrench when removing or installing brake
tubes.
+Always torque brake lines when installing.
+Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off the new lock nut
before tightening.

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.

+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.
