Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
Indicated unbalance value
5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz)
5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
a. Install balance weight in the position shown in the figure at right.
b. When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the wheel
balancer indication position (angle).
CAUTION:
Always use genuine Nissan adhesion balance weights.
Balance weights are unreusable; always replace with new
ones.
Do not install more than three sheets of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 7.5 g (0.26 oz) each or below.
If either residual unbalance value exceeds 7.5 g (0.26 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
SMA054D
SEIA0271E
Maximum allowable
unbalanceDynamic (At rim flange) Less than 7 g (0.25 oz) (one side)
Static (At rim flange) Less than 14 g (0.50 oz)

Tire RotationNLS00088
After rotation the tires, adjust the tire pressure.
Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
Do not include the T-type spare tire when rotating the tires.
When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
Checking Brake Fluid Level and LeaksNLS00089
If fluid level is extremely low, check brake system for leaks.
Checking Brake Lines and CablesNLS0008A
Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasions, deterioration, etc.
Changing Brake FluidNLS0008B
1. Drain brake fluid from each bleed valve.
2. Refill until new brake fluid comes out from each bleed valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to BR-11, "
Bleeding Brake System" .
Refill with recommended Genuine Nissan Super Heavy Duty
Brake Fluid or equivalent DOT 3 (US FMVSS No. 116).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas.Tightening torque of wheel nut

Checking Power Steering Fluid and LinesNLS0008E
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80
C (122 to 176F)
or “COLD” range at fluid temperatures of 0 to 30
C (32 to 86F).
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 PartsNLS0008F
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.
Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

Checking Seat Belt, Buckles, Retractors, Anchors and AdjustersNLS0008I
CAUTION:
After any collision, inspect all seat belt assemblies, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in
use during a collision, unless not damaged and properly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision, and replace if damaged or improp-
erly operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal col-
lision where the driver and passenger air bags are deployed.
If any component of seat belt assembly is questionable, do not repair.
Replace as seat belt assembly.
If webbing is cut, frayed, or damaged, replace belt assembly.
Never oil tongue and buckle.
Use a genuine NISSAN seat belt assembly.
For details, refer to SB-33, "
Seat Belt Inspection" in SB section.
Check anchors for loose mounting
Check belts for damage
Check retractor for smooth operation
Check function of buckles and tongues when buckled and released
