4. Attach the circlip to the shaft. The circlip must fit securely into
the shaft groove. Attach the nut to the joint sub-assembly.
Use a suitable tool to press-fit the circlip.
NOTE:
Discard the old circlip and use a new one for assembly.
5. Insert the specified quantit y of Genuine NISSAN Grease or
equivalent, into the housing from the large end of the boot. Refer
to MA-12, "Fluids and Lubricants"
.
6. Install the boot securely into the grooves (indicated by the * marks) as shown.
CAUTION:
If there is grease on the boot mating surfaces (indicated by
the * marks) of the shaft and housing, the boot may come
off. Remove all grease from the shaft surfaces.
7. Check that the boot installation length (L) is the specified length. Insert a flat-tip screwdriver or similar tool into the large end of
the boot. Bleed the air from the boot to prevent boot deforma-
tion.
CAUTION:
 The boot may break if the boot installation length is less than the specified length.
 Do not contact inside surface of boot with the tip of the screwdriver.
8. Secure large and small ends of the boot using new boot bands using tool as shown.
NOTE:
Discard the old boot bands and use new ones for assembly.
 Secure boot band so that dimension (M) meets specificationas shown.
9. After installing the housing to the shaft, rotate the boot to check that it is positioned correctly. If the boot is
not positioned correctly, remove the old boot bands then reposition the boot and secure the boot with new
boot bands. Grease capacity : 140

ON-VEHICLE MAINTENANCE
POWER STEERING FLUID
Checking Fluid LevelINFOID:0000000004187604
Check power steering fluid level with engine off, referring to the scale
on reservoir tank.
Use HOT range for fluid temperatures of 50 ° – 80 °C (122 ° – 176 °F).
Use COLD range for fluid temperatures of 0 ° – 30 °C (32 ° – 86 °F).
CAUTION:
 Do not overfill.
 Do not reuse any used power steering fluid.
 Recommended fluid is Genuine NISSAN PSF or equivalent. Refer to MA-12, "Fluids and Lubricants"
.
Checking Fluid LeakageINFOID:0000000004187605
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50 ° – 80 °C (122 ° –
176 °F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loos en flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to ST-17
.
6. Check steering gear boots for accumulation of fluid indicating a leak from the steering gear.
Air Bleeding Hydraulic SystemINFOID:0000000005873142
NOTE:
 When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from oil pump or gear. This noise is normal and does not affect any system.
 Incomplete air bleeding causes the fo llowing. When this happens, bleed air again.
- Air bubbles in reservoir tank.
- Clicking noise in oil pump.
- Excessive buzzing in oil pump.
1. Stop engine, and then turn steering wheel fully to right and left several times. CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds.
Then check for fluid leakage.
3. Repeat step 2 several times at about three second intervals. CAUTION:
Do not hold steeri ng wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that oil pump may be damaged.)
4. Check for air bubbles or cloudy fluid.
5. If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloud-
iness does not exist.
