Checking Power Steering Fluid and LinesNLS00070
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80 °C (122 to 176 °F)
or “COLD” range at fluid temperatures of 0 to 30 °C (32 to 86 °F).
CAUTION:

Do not overfill.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS"


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS00071
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Axial End Play

Apply load of 490 N (50 kg, 110 lb) to ball stud axially. Use a dial
gauge to measure the amount of the movement that the stud
makes. Check if the reading is within the specified below. If the
value is outside the standard, replace outer and inner sockets.
ASSEMBLY
1. Apply recommended fluid to O-ring. Put an O-ring into rack Teflon ring.
2. Heat rack Teflon ring to approximately 40 °C (104 °F) with a
dryer. Assemble it to mounting groove of rack.
3. To fit rack Teflon ring on rack, use rack Teflon ring installation tool (SST) from tooth side. Compress rim of ring with the tool.
4. Apply recommended grease to rack oil seal. Insert rack oil seal, then insert rack assembly to gear housing assembly.
CAUTION:

When inserting rack assembly, do not damage retainer
sliding part. If it is damaged, replace gear housing
assembly.

When inserting rack assembly, do not damage cylinder
inner wall. If it is damaged, it may cause oil leaks.
Replace gear housing assembly.

Attach rack oil seal. Both inner lip and outer lip should
face each other.
Outer socket 0.5 mm (0.02 in) or less
Inner socket 0.2 mm (0.01 in) or less

a. To avoid damaging inner rack oil seal, wrap an OHP sheet
[approximately. 70 mm (2.76 in) × 100 mm (3.94 in) around rack
tooth. Place oil seal on sheet. Then, pull oil seal along with OHP
sheet until they pass the toothed section of rack, then remove it.
b. Insert rack oil seal (inner) to piston (rack Teflon ring) position and push retainer to adjust screw side with fingers lightly, and
then make rack move in gear housing assembly, install rack oil
seal (inner) to fit with gear housing assembly.
c. When installing outer rack oil seal, cover the end of rack with an OHP sheet [70 mm (2.76 in) × 100 mm (3.94 in)]. It will avoid
damaging rack oil seal. Then place oil seal on sheet. Pull rack oil
seal along with OHP sheet until they pass rack end. Then
remove OHP sheet.
d. Install end cover assembly to rack, move it to gear housing assembly.
5. Using a 45 mm (1.77 in) open head (suitable tool), tighten end cover assembly at the specified torque.
CAUTION:
Do not damage rack surface. If it is damaged, it may cause
oil leaks. Replace rack assembly.
6. After tightening end cover assembly, caulk cylinder at one point as shown in the figure using a punch. This will prevent end cover
from getting loose.
7. Install pinion assembly to gear housing assembly. CAUTION:
In order to protect oil seal from any damage, insert pinion
assembly out straightly.
8. Apply recommended fluid to O-ring. Install O-ring to rear cover.
9. Use a rear cover wrench (SST), install rear cover to gear hous- ing assembly.

5. Remove cam ring, rotor, vane, front side plate, flow control valve
A, spring, flow control valve B assembly and O-ring from body
assembly.
CAUTION:
Be careful not to drop and deform flow control valve A and
flow control valve B assembly.
6. Remove suction pipe from body assembly.
7. Remove O-ring from suction pipe.
8. Remove bracket from body assembly.
INSPECTION AFTER DISASSEMBLY
Body Assembly and Rear Cover Inspection
Check body assembly and rear cover for internal damage. Replace rear cover if it is damaged. Replace oil
pump assembly if body assembly is damaged.
Cartridge Assembly Inspection
Check cam ring, rotor and vane for damage. Replace cartridge assembly if necessary.
Side Plate Inspection
Check side plate (front and rear) for damage. Side plate (front and rear) must be replaced as a set if they are
damaged.
Flow Control Valve Inspection
Check flow control valve A, flow control valve spring and flow control valve B assembly for damage. Replace if
there are.
ASSEMBLY
NOTE:
Fix oil pump in vise as occasion demands.
CAUTION:
When retaining drive shaft in a vise, always use copper or aluminum plates between vise and shaft.
1. Apply recommended grease to oil seal lips. Apply recommended fluid to around oil seal, and then install oil seal to body assembly
using the drift [SST].
2. If dowel pin has been removed, insert it into body assembly by hand. If it cannot be inserted by hand, lightly tap with a hammer.
3. Install flow control valve A, flow control valve spring and flow control valve B assembly to locations shown in the figure.
