PERIODIC MAINTENANCE

REAR SUSPENSION ASSEMBLY

On-vehicle Service

INFOID:0000000009177390

• Check the suspension parts for excessive play, cracks, wear or damage. Shake each rear wheel to check for

excessive play.

• Retighten all nuts and bolts to the specified torque.

• Make sure that each cotter pin is installed (if equipped).

• Check the shock absorber for oil leakage or other damage.

• Check the wheelarch height. Refer to

RSU-23, "Wheelarch

Height"

• Check the suspension ball joint for grease leakage and the ball

joint dust cover for cracks or other damage.

Inspection

INFOID:0000000009177391

SHOCK ABSORBER ASSEMBLY

• Check for smooth operation through a full stroke for both compression and extension.

• Check for oil leakage on the welded or gland packing portions.

• Check the shock absorber piston rod for cracks, deformation or other damage and replace if necessary.

SUSPENSION ARM

• Check the suspension arm for damage, cracks, deformation and replace if necessary.

• Check the rubber bushings for damage, cracks and deformation. Replace suspension arm if necessary.

• Check the ball joint. Replace the suspension arm assembly if any

of the following conditions exist:

- Ball stud is worn.

- Joint is hard to swing.

- Check if the swinging force (A), rotating torque (B), or vertical end

play (C) is out of specification using Tool.

NOTE:

Before checking specifications, turn the ball joint at least 10 revolu-

tions so the ball joint is properly broken in.

RADIUS ROD

• Check the radius rod for any deformation, cracks, or damage and replace if necessary.

• After installing the radius rod, check the wheel alignment and adjust if necessary. Refer to

RSU-23, "Wheel

Alignment (Unladen*)"

FRONT LOWER LINK

• Check the front lower link for any deformation, cracks, or damage and replace if necessary.

UPPER AND LOWER RUBBER SEATS

• Check the upper and lower rubber seats for deterioration or cracks and replace if necessary.

REAR SUSPENSION ASSEMBLY

• Check the rear lower link and coil spring for any deformation, cracks, or other damage and replace if neces-

sary.

STABILIZER BAR

• Check the stabilizer bar and clamps for any deformation, cracks or damage and replace if necessary.

• Check the rubber bushings for deterioration or cracks and replace if necessary.

Inspection and Adjustment

INFOID:0000000009177392

Before checking the rear wheel alignment, make a preliminary inspection.

• Measure the wheel alignment under unladen conditions.

NOTE:

Unladen conditions mean that fuel, engine coolant, and lubricants are full and that the spare tire, jack, hand

tools and mats are in their designated positions.

PRELIMINARY INSPECTION

• Check the tires for wear and for improper inflation.

• Check the wheels for deformation, cracks, and other damage. Remove the wheel and check the wheel

runout. Refer to

WT-58, "Adjustment"

• Check the rear wheel bearings for looseness.

• Check the rear suspension for looseness.

• Check that the rear shock absorbers work properly.

• Check the wheelarch height in the unladen condition. Refer to

RSU-23, "Wheelarch Height"

GENERAL INFORMATION AND RECOMMENDATIONS

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

• This type of alignment is recommended for any NISSAN/INFINITI 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/INFINITI 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-23, "Wheel

Alignment (Unladen*)"

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. Most camera-type alignment machines are equipped with both "Rolling Compensation" method and

optional "Jacking Compensation" method to "compensate" the alignment targets or head units.

"Rolling Compensation" is the preferred method.

• If using the "Rolling Compensation" method, after installing the alignment targets or head units, push or

pull on the rear wheel to move the vehicle. Do not push or pull the vehicle body.

• If using the "Jacking Compensation" method, after installing the alignment targets or head units, raise

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

NOTE:

Do not use the "Rolling Compensation" method if you are using sensor-type alignment equipment.

• Follow all instructions for the alignment machine you're using for more information.

CAMBER

• Measure the camber of both the right and left wheels using a suitable alignment gauge and adjust using the

following procedure.

RSU-23, "Wheel Alignment (Unlad-

en*)"
