REAR SUSPENSION ASSEMBLY

On-Vehicle Inspection and Service

INFOID:0000000005148129

Check all of the component mountings for any excessive looseness, or back lash. Check the components for

any excessive wear, damage, or abnormal conditions. Repair or replace the components as necessary.

SHOCK ABSORBER INSPECTION

• Check the shock absorbers for any air leaks or damage, and replace as necessary.

• Check the hoses for any air leaks or damage, and replace as necessary.

Wheel Alignment Inspection

Rear Wheel Alignment Adjusting Bolts

PRELIMINARY INSPECTION

WARNING:

Always adjust the alignment with the vehicle on a flat surface. Use CONSULT-III “EXHAUST SOLE-

NOID” active test to release the air pressure from the rear load leveling air suspension system.

NOTE:

If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before

making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”

means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in

their designated positions.

2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for runout and damage. Refer to 

WT-47, "Inspection"

 .

4. Check the wheel bearing axial end play.

5. Check the shock absorbers. Refer to 

RSU-15, "Removal and Installation"

 .

6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer to 

RSU-30, "Wheelarch Height (Unladen*

1

)"

 .

• If vehicle height is not within 

± 10 mm (0.39 in) of the specification, perform the control unit initialization

procedure. Refer to 

RSU-26, "Initialization Procedure"

 .

GENERAL INFORMATION AND RECOMMENDATIONS

1. A Four-Wheel Thrust Alignment should be performed.

• This type of alignment is recommended for any NISSAN vehicle.

• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel

is centered.

• The alignment machine itself should be capable of accepting any NISSAN vehicle.

• The alignment machine should be checked to ensure that it is level.

2. Make sure the alignment machine is properly calibrated.

• Your alignment machine should be regularly calibrated in order to give correct information.

• Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-

bration Schedule.

THE ALIGNMENT PROCESS

IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to 

RSU-29, "Wheel

Alignment"

 .

1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or

minus, Go/No Go). Do NOT use these indicators.

• The alignment specifications programmed into your alignment machine that operate these indicators

may not be correct.

• This may result in an ERROR.

2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-

pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”

method.

• Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the

vehicle and rotate the wheels 1/2 turn both ways.

• See Instructions in the alignment machine you are using for more information.

CAMBER

1. Measure camber of both the right and left wheels with a suitable

alignment gauge and adjust as necessary to specification.

2. If outside of the specified value, adjust the camber using the

adjusting bolt in the front lower link.

CAUTION:

After adjusting the camber then check the toe-in.

NOTE:

Camber changes about 0

° 5' with each graduation of the adjust-

ing bolt.

3. Tighten the adjusting bolt nuts to specification.

TOE-IN

1. Bounce the rear of the vehicle up and down two to three times to stabilize the vehicle height. Refer to

RSU-30, "Wheelarch Height (Unladen*

1

)"

 .

2. Push the vehicle straight ahead about 5 m (16 ft).

3. Put a mark on the base line of the tread (rear side) of both of the

tires at the same height as the center of the hub. This will be the

measuring points.

4. Measure the distance (A)  from rear side across from tire to tire.
5. Push the vehicle slowly ahead to rotate the wheels 180

° (a half

turn).

If the wheels are rotated more than 180

° (a half turn), then

repeat the above steps. Never push the vehicle backward.

6. Measure the distance (B) from front side across from tire to tire.

7. If the toe-in is outside the specified value, adjust the toe-in using

the adjusting bolt in the rear lower link.

CAUTION:

Be sure to adjust equally on RH and LH sides using the

adjusting bolt.

NOTE:

Toe changes about 1.5 mm (0.059 in) [one side] with each grad-

uation of the adjusting bolt.

8. Tighten the adjusting bolt nuts to specification.
