InspectionNJST0020+When steering wheel does not turn smoothly, check the steer-
ing column as follows and replace damaged parts.
a) Check column bearings for damage or unevenness. Lubricate
with recommended multi-purpose grease or replace steering
column as an assembly, if necessary.
b) Check jacket tube for deformation or breakage. Replace if
necessary.
+When the vehicle comes into a light collision, check length ªLº.
Steering column length ªLº:
Refer to SDS, ST-33.
If out of the specifications, replace steering column as an assem-
bly.

CAUTION:
+The rotation of the spiral cable (SRS ªAir bagº component
part) is limited. If the steering gear must be removed, set
the front wheels in the straight-ahead direction. Do not
rotate the steering column while the steering gear is
removed.
+Remove the steering wheel before removing the steering
lower joint to avoid damaging the SRS spiral cable.
+Detach tie-rod outer sockets from knuckle arms with Tool.
1. Remove stabilizer fixing bolts. Refer to SU-11, ªRemoval and
Installationº.
2. Disconnect lower joint.
3. Remove gear housing mounting bracket fixing bolts.
4. Remove steering gear assembly.

+Install pipe connector.
+Observe specified tightening torque when tightening high-pres-
sure and low-pressure pipe connectors. Excessive tightening
will damage threads of connector or O-ring.
Connector tightening torque:
1 Low-pressure side
27 - 39 N´m (2.8 - 4.0 kg-m, 20 - 29 ft-lb)
2 High-pressure side
15 - 25 N´m (1.5 - 2.5 kg-m, 11 - 18 ft-lb)
+The O-ring in low-pressure pipe connector is larger than that
in high-pressure connector. Take care to install the proper
O-ring.
SST824A
+Initially, tighten nut on tie-rod outer socket and knuckle arm to
29 to 39 N´m (3 to 4 kg-m, 22 to 29 ft-lb). Then tighten further
to align nut groove with first pin hole so that cotter pin can be
installed.
CAUTION:
Tightening torque must not exceed 49 N´m (5 kg-m, 36 ft-lb).
NOTE:
Only the dust boot, tie-rod inner socket and tie-rod outer socket can
be disassembled on models for Europe.
SST819A
+Before removing lower joint from gear, set gear in neutral
(wheels in straight-ahead position). After removing lower joint,
put matching mark on pinion shaft and pinion housing to record
neutral position.
+To install, set left and right dust boots to equal deflection.
Attach lower joint by aligning matching marks of pinion shaft
and pinion housing.
+Tighten gear housing mounting bracket bolts.
SST862CB
DisassemblyNJST00231. Prior to disassembling, measure pinion rotating torque. Record
the pinion rotating torque as a reference.
+Before measuring, disconnect gear housing tube and
drain fluid.
+Use soft jaws when holding steering gear housing. Handle
gear housing carefully, as it is made of aluminum. Do not
grip cylinder in a vise.
2. Remove gear sub-assembly, O-ring and shim.
Gear sub-assembly cannot be disassembled. If it is faulty,
replace with a new one.

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.
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.
