+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.

3. Remove tie-rod outer sockets and boots.
4. Loosen tie-rod inner socket by prying up staked portion, and
remove socket and spacer.
5. Remove retainer.
6. Usea2to2.5mm(0.079 to 0.098 in) diameter drill to com-
pletely remove staked portion of gear housing end.
SST052C
7. Remove end cover assembly with a suitable tool.
8. Draw out rack assembly.
9. Remove rack seal ring.
+Using a heat gun, heat rack seal to approximately 40ÉC
(104ÉF).
+Remove rack seal ring.
Be careful not to damage rack.
SST472A
10. Remove center bushing and rack oil seal using tape wrapped
socket and extension bar.
Do not scratch inner surfaces of pinion housing.
InspectionNJST0024Thoroughly clean all parts in cleaning solvent or DEXRONTMIII or
equivalent. Blow dry with compressed air, if available.
BOOTNJST0024S01+Check condition of boot. If cracked excessively, replace it.
+Check boots for accumulation of power steering fluid.
RACKNJST0024S02Thoroughly examine rack gear. If damaged, cracked or worn,
replace it.
GEAR SUB-ASSEMBLYNJST0024S03+Check pinion gear. If it is worn or damaged, replace as a gear
sub-assembly.
+Manually spin bearing. If torque variations or free play are
noted, replace as a gear sub-assembly.
GEAR HOUSING CYLINDERNJST0024S04Check gear housing cylinder bore for scratches or other damage.
Replace if necessary.

16. Before installing boot, coat the contact surfaces between boot
and tie-rod with grease.
SST868C
17. Install boot bands.
+Securely install boot band to boot groove and clinch the root
section of the trapezoidal area.
+Make sure that there is a clearance of 3.5 mm (0.138 in) or less
at the clinched section of the boot band. Refer to the Figure at
left.
SST869C
+After installing gear in vehicle, make sure that the clinched
section of boot band is positioned toward the rear of vehicle (to
prevent interference with adjacent parts).
SST719C
AdjustmentNJST0026Adjust pinion rotating torque as follows:
1. Set rack to the neutral position without fluid in the gear.
2. Coat the adjusting screw with locking sealant and screw it in.
3. Lightly tighten lock nut.
4. Tighten adjusting screw to a torque of 4.9 to 5.9 N´m (50 to 60
kg-cm, 43 to 52 in-lb).
5. Loosen adjusting screw, then retighten it to 0.2 N´m (2 kg-cm,
1.7 in-lb).
SST862CB
6. Move rack over its entire stroke several times.
7. Measure pinion rotating torque within the range of 180É from
neutral position.
Stop the gear at the point of maximum torque.
8. Loosen adjusting screw, then retighten it to 4.9 N´m (50 kg-cm,
43 in-lb).
9. Loosen adjusting screw by 50É to 70É.

+Check stabilizer for deformation or cracks. Replace if neces-
sary.
+Check rubber bushings for deterioration or cracks. Replace if
necessary.
+Check ball joint can rotate in all directions. If movement is not
smooth and free, replace stabilizer bar connecting rod.
