1998 NISSAN PICK-UP wheel alignment

lAll dimensions indicated in figures are actual ones.
lWhen using a tracking gauge, adjust both pointers to equal length. Make sure there is no free play.
lWhen a measuring tape is used, check to be sure there is no elongation, twisting or bending.
lMeasurements should be taken at the center of the mounting holes.
lAll measurements and mounting hole diameters are expressed in millimeters (mm).
lAn asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.
lThe coordinates of the measurement points are the distances measured from the respective dimension
lines in the directions of ``x'', ``y'' and ``z''.
Dimension lines: ``x'' line Ð Center line of vehicle
``y'' line Ð Center line of front axle (Any measurement point in front of the dimension
line refers to a minus ``Ð'' value.)
``z'' line Ð Datum line (Any measurement point under the dimension line refers to a
minus ``Ð'' value.)

Precautions
lWhen installing rubber parts, final tightening must be
carried out under unladen condition* with tires on
ground.
* Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
lAlways torque brake lines when installing.

PRECAUTIONS AND PREPARATION
FA-1

7. Turn wheel hub several times in both directions.
8. Retighten wheel bearing lock nut with Tool.
: 0.5 - 1.5 N´m (0.05 - 0.15 kg-m, 4.3 - 13.0 in-lb)
9. Measure wheel bearing axial end play.
Axial end play: 0 mm (0 in)
10. Measure starting force ``A'' at wheel hub bolt.
11. Install lock washer by tightening the lock nut within 15 to 30
degrees.
12. Turn wheel hub several times in both directions to seat wheel
bearing correctly.
13. Measure starting force ``B'' at wheel hub bolt. Refer to step
10.
14. Wheel bearing preload ``C'' can be calculated as shown
below.
C=BþA
Wheel bearing preload ``C'':
7.06 - 20.99 N (0.72 - 2.14 kg, 1.59 - 4.72 lb)
15. Repeat steps 3 through 14 until correct axial end play and
wheel bearing preload are obtained.
16. Install free-running hub.
Front Wheel Alignment
Before checking front wheel alignment, make a preliminary
inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and proper inflation.
2. Check outside and inside wheel runout.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly by using the
standard bounce test.
