Removal and InstallationNGS0000B
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-40, "
Removal and Installation" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller A.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-10, "Removal and Installation" .
NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to SRS-42, "
Removal and
Installation" . Tool number A: ST27180001 (J-25726-A)

INSPECTION AFTER REMOVAL

Check if there is something wrong with jacket tube of steering column assembly and collar etc. And then if
they are damaged, replace with new one.

If vehicle has a collision light shocked, check column length “L”
as shown in the figure. Then if it is out of the specified value,
replace with new one.

Check the turning torque of steering column with preload gauge
(SST: ST3127S000 [J-25765-A]). If it is out of the specified
value, repair it or replace with new one.
INSTALLATION
1. Install collar to lower shaft.
2. Install yoke of column shaft to collar, tack bolt and nut.Specified value
Steering column length “L”: 548 mm (21.57 in)
Specified value
Turning torque : 0 - 0.2 N·m (0 - 0.02 kg-m, 0 - 2 in-lb)

STEERING COLUMN
Revision: 2006 November2007 350Z
3. Put steering column assembly (installation hole “P”) on bolt for
steering member side and install nut “A” then tighten it together
with the other bolts at the specified torque.
4. Connect yoke and collar with bolt, tighten nut at the specified
torque.
INSPECTION AFTER INSTALLATION

After installing steering column to vehicle, check tilt device and
its operation range “L
1” , “L2” .

Check if steering operation can turn to the end of the left and
right smoothly.
SGIA0371E
Tilt operating range “L1 ” : 28 - 32 mm (1.10 - 1.26 in)
“L
2 ” : 13 - 17 mm (0.51 - 0.67 in)

c. Lock adjusting bolt, then remove lock nut.
d. Remove adjusting bolt, adjusting stopper, column mounting
bracket, tilt lever stopper and tilt lever from jacket tube.
INSPECTION AFTER DISASSEMBLY

Check if there is something wrong with steering column shaft and bearing. And then if they are damaged,
replace with new one.

Check if there is something wrong with the component of tilt device. And then if it is damaged, replace
with new one.
ASSEMBLY
1. Install tilt device to jacket tube. Refer to PS-15, "Disassembly and Assembly" .
NOTE:

Turn tilt lever to unlock side while at work to make it easier.

That can avoid column shaft's sudden descent when tilt lever
is operated on vehicle.
2. When tilt lever is in the locked position (operation range is about
40°), tighten lock nut at the specified torque to make tilt lever
locked.
3. Apply grease to the part shown in the figure of component. Refer
to PS-15, "
Disassembly and Assembly" .
4. Install steering column shaft to jacket tube, tighten steering col-
umn shaft lock nut at the specified torque.

Tightening torque:
13.5 - 18.6 N·m (1.4 - 1.8 kg-m, 10 - 13 ft-lb)
Tightening torque : 25 - 34 N·m (2.6 - 3.4 kg-m, 19 - 25 ft-lb)

8. Loosen bolt on upper yoke of lower joint and remove bolt on
lower yoke of joint, then slide lower joint into lower shaft. Sepa-
rate steering gear assembly from lower shaft.
9. Tack bolt on upper yoke of lower joint, fix lower joint to lower
shaft.
10. Remove the fixing bolt and remove steering gear assembly, rack
mounting bracket and insulator from vehicle.
INSTALLATION

Refer to PS-17, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

When steering wheel is set in the straight ahead direction, con-
firm slit of lower joint fits with the projection on rear cover cap,
furthermore marking position on steering gear assembly nearly
fits with the projection on rear cover cap.

After installation, bleed air from piping. Refer to PS-6, "Air
Bleeding Hydraulic System" .

11. Heat rack Teflon ring to approximately 40°C (104°F) with a
dryer, then remove it and O-ring A from rack assembly.
CAUTION:
Be careful not to damage rack. If it is damaged, change to a
new one to avoid oil leaks.
12. Use a taped 29 mm (1.14 in) socket and an extension bar.
Remove rack oil seal from gear housing assembly.
CAUTION:
Be careful not to damage gear housing assembly and cylin-
der inner wall. If it is damaged, gear housing assembly
must be replaced. Otherwise, oil leaks will result.
INSPECTION AFTER DISASSEMBLY
Boot
Check boot for cracks and deformation. Replace it, if necessary.
Rack Assembly
Check rack for damage and wear. Replace it, if necessary.
Gear-sub Assembly

Check pinion gear for damage or wear. Replace if necessary.

Rotate pinion and check for torque variation or rattle. Replace if necessary.
Gear Housing Assembly
Check gear housing assembly for damage and scratches (inner wall). Replace it, if necessary.
Outer Socket and Inner Socket
Swing Torque

Hook a spring balance at the point shown in the figure. Confirm
if the reading is within the specification. When ball stud and
inner socket start moving the measured value must be within the
specification. If the reading is outside the specification, replace
socket.
