CAUTION:
I
The rotation of the spiral cable (SRS “Air bag” 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.
I
Remove the steering wheel before removing the steering
lower joint to avoid damaging the SRS spiral cable.
I
Detach tie-rod outer sockets from knuckle arms with Tool.
1.
Remove stabilizer fixing bolts. Refer to SU-12, “Removal and

SST879C
I
Install pipe connector.
I
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)
I
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
I
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
I
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.
I
To install, set left and right dust boots to equal deflection.
Attach lower joint by aligning matching marks of pinion shaft
and pinion housing.
I
Tighten gear housing mounting bracket bolts.
Inspection

1.
Check rack sliding force on vehicle as follows:
a.
Install steering gear onto vehicle, but do not connect tie-rod to
knuckle arm.
b.
Connect all piping and fill with steering fluid.
c.
Start engine and bleed air completely.
d.
Disconnect steering column lower joint from the gear.
e.
Keep engine at idle and make sure steering fluid has reached
normal operating temperature.
f.
Pull tie-rod slowly to move it from neutral position to
±
11.5 mm
(
±
0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
197 - 255 N (20.1 - 26.0 kg, 44.3 - 57.3 lb)
BOOT
NLST0024S01
I
