PRECAUTIONS
2005 Pathfinder
PRECAUTIONS
PFP:00001
Precautions
EES0019K
●
When installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.
●
Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.
●
After installing suspension components, check the wheel alignment.
●
Lock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.

Front Suspension Parts
EES0019P
Check front suspension parts for excessive play, cracks, wear and
other damage.
●
Shake each front wheel to check for excessive play.
If looseness is noted, inspect wheel bearing end play, then
check ball joint end play. Refer to
.
●
Make sure that the cotter pin is inserted in drive shaft end (4x4
only).
●
Retighten all nuts and bolts to the specified torque.
●
Check shock absorber for oil leakage and other damage.
●
Check suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel Alignment
EES0019Q
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
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 run out and damage. Refer to
.
4.
Check the wheel bearing axial end play. Refer to
FAX-5, "WHEEL BEARING INSPECTION"
.
5.
Check the shock absorbers for leaks or damage.
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
FSU-19, "Wheelarch Height (Unladen*
.
CAMBER AND CASTER
1.
Measure camber and caster 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 camber and caster using
the adjusting bolts in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.05
°
) minutes with each graduation
of one adjusting bolt. Refer to table below for examples of lower
link adjusting bolt effect on camber and caster.
3.
Tighten the adjusting bolt nuts to specification. Refer to
.
TOE-IN
WARNING:
●
Always perform the following procedure on a flat surface.
●
Make sure that no person is in front of the vehicle before pushing it.
1.
Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2.
Push the vehicle straight ahead about 5 m (16 ft).
3.
Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.
4.
Measure the distance “A” on the rear side of the front tires as
shown.
5.
Push the vehicle slowly ahead to rotate the wheels 180
°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180
°
degrees (1/2
turn), start this procedure again from the beginning. Never
push the vehicle backward.
6.
Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.

Adjust the toe-in by varying the length of the steering outer tie-
rods.
a.
Loosen the outer tie-rod lock nuts.
b.
Adjust the toe-in by screwing the outer tie-rods in or out.
c.
Tighten the outer tie-rod lock nuts to specification.
FRONT WHEEL TURNING ANGLE
NOTE:
Check front wheel turning angle after the toe-in inspection.
1.
Place front wheels on turning radius gauges in straight ahead
position and rear wheels on stands so that vehicle can be level.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
2.
Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.
●
Any turning angles are not adjustable. If any of steering
angles are out of the specification, check if the following parts
are worn or damaged.
–
Steering gear
–
Steering column
–
Front suspension components
If found that they are worn or damaged, replace them with new ones.
