2006 NISSAN PATROL wheel bearings

4. Measure outer diameter ``Dp'' of each crankshaft pin journal.
5. Calculate connecting rod bearing clearance.
Connecting rod bearing clearance=CþDp:
Standard
0.014 - 0.054 mm (0.0006 - 0.0021 in)
Limit
0.090 mm (0.0035 in)
If it exceeds the limit, replace bearing.
+If it still exceeds the limit even with a new bearing, regrind crank
pin and use undersized bearings.
+Refer to SDS for regrinding crankshaft and available ser-
vice parts.
Method B (Using plastigage)
CAUTION:
+Do not turn crankshaft or connecting rod while plastigage
is being inserted.
+If incorrect bearing clearance exists, use a thicker or
undersized main bearing to ensure speci®ed clearance.
CONNECTING ROD BUSHING CLEARANCE (Small end)
1. Measure inner diameter ``C'' of bushing.
2. Measure outer diameter ``Dp'' of piston pin.
3. Calculate connecting rod bushing clearance.
Connecting rod bushing clearance=CþDp
Standard:
0.025 - 0.044 mm (0.0010 - 0.0017 in)
If it exceeds the limit, replace connecting rod assembly or con-
necting rod bushing and/or piston set with pin.
REPLACEMENT OF CONNECTING ROD BUSHING
(Small end)
1. Drive in small end bushing until it is ¯ush with end surface of
rod.
Be sure to align the oil holes.
2. Ream the bushing so that clearance with piston pin is within
speci®cation.
Clearance between connecting rod bushing and pis-
ton pin:
0.005 - 0.017 mm (0.0002 - 0.0007 in)
FLYWHEEL/DRIVE PLATE RUNOUT
Runout (Total indicator reading):
Less than 0.15 mm (0.0059 in)
CAUTION:
+Be careful not to damage the ring gear teeth.
+Check the drive plate for deformation or cracks.
+Do not allow any magnetic materials to contact the ring
gear teeth.
+Do not resurface drive plate. Replace as necessary.

Front Axle and Front Suspension Parts
Check front axle and front suspension parts for excessive play,
cracks, wear and other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspensions nuts and bolts to the speci-
®ed torque.
Tightening torque:
Refer to FRONT SUSPENSION (FA-24).
+Check front axle and front suspension parts for wear, cracks
and other damage.
+Check shock absorber for oil leakage and other damage.
+Check knuckle ¯ange for grease leakage and knuckle ¯ange
grease seal for cracks and other damage.
Front Wheel Bearing
+Check that wheel bearings operate smoothly.
+Check axial end play.
Axial end play:
0mm(0in)
+Adjust wheel bearing preload if there is any axial end play or
wheel bearing does not turn smoothly.

19. Pack drive ¯ange groove with grease, apply grease to O-ring
and mating surface of drive ¯ange, and install ¯ange.
20. Place snap ring in drive shaft groove. Choose snap ring so that
the gap between groove and snap ring is 0.4 mm (0.016 in) or
less.
Refer to SDS for selection of snap ring.
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a prelimi-
nary 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 improper in¯ation.
2. Check wheel runout on outside and inside.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS (FA-27).
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that shock absorbers work properly.
7. Check vehicle posture (Unladen).
CAMBER, CASTER AND KINGPIN INCLINATION
Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, Caster and Kingpin inclination:
Refer to SDS (FA-27).
2. If camber, caster or kingpin inclination is not within
speci®cation, inspect front suspension parts. Replace damaged
or worn out parts.

8. Separate brake disc to hub.
Inspection
Thoroughly clean wheel bearings and wheel hub.
WHEEL BEARING
+Make sure wheel bearing rolls freely and is free from noise,
crack, pitting or wear.
WHEEL HUB
+Check wheel hub for crack by using a magnetic exploration or
dyeing test.
Assembly
1. Install bearing outer race with Tool until it seats in hub.
2. Install the sensor rotor using suitable drift and press. (Models
with ABS)
Always replace sensor rotor with new one.
Pay attention to the direction of front sensor rotor as shown in
®gure.
3. Pack multi-purpose grease to hub and hub cap.

Limited-slip differential gear
+ Use only approved or recommended limited-slip differential
gear oil.

(1) Lift both rear wheels off the ground.
(2) Turn one rear wheel by hand.
(3) If both rear wheels turn in the same direction simultaneously, vehicle is equipped with limited-slip differential.
Checking Front Wheel Bearing Grease
+Check that wheel bearings operate smoothly.
+ Check front wheel bearings for grease leakage and water or
dust entry.
+ Replace front wheel bearings or front wheel bearing grease if
wheel bearings do not turn smoothly.

age. Replace if necessary.
+When the vehicle comes into a light collision, check length ``L
1''
and ``L
2''.
Steering column length ``L
1'':
