GENERAL MAINTENANCE
(2006/01- )
1. INSPECT STEERING LINKAGE AND GEAR HOUSING
(a) Check the steering wheel free play.
(b) Check the steering linkage for looseness or
damage.
(1) Check that the tie rod ends do not have
excessive play.
(2) Check that the dust seals and boots are not
damaged.
(3) Check that the boot clamps are not loose.
(4) Check that the steering gear housing is not
damaged.
(5) Check that the connectors are properly
connected to the steering gear housing.
2. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(1) Jack up the front of the vehicle and place
wooden blocks with a height of 180 to 200 mm
(7.09 to 7.87 in.) under the front tires.
(2) Lower the vehicle until the front coil spring has
about half its ordinary load. Place stands under
the vehicle for safety.
(3) Check that the front wheels are pointing
straight ahead. Use wheel chocks on all 4
wheels.
(4) Using a lever, pry up the end of the lower arm.
Check the amount of play.
Maximum ball joint vertical play:
0 mm (0 in.)
If there is any play, replace the ball joint.
(b) Check the dust cover for damage.
3. INSPECT DRIVE SHAFT BOOTS
(a) Check the drive shaft boots for loose clamps,
grease leakage, kinks or damage.
4. INSPECT AUTOMATIC TRANSAXLE FLUID LEVEL
(a) Visually check the transmission for fluid leakage. If
oil is leaking, find the cause and repair it.
5. INSPECT TRANSFER OIL (for 4WD)
(a) Visually check the transfer for oil leakage. If oil is
leaking, find the cause and repair it.
6. INSPECT REAR DIFFERENTIAL OIL (for 4WD)
(a) For the rear differential oil inspection, refer to the
following procedures (see page DF-3).

NOTICE:
Do not use an air gun to perform the
smooth operation check.
(d) Check the lock in the extreme retard position.
(1) Confirm that the camshaft timing gear is locked
at the extreme retard position.
5. INSPECT CAMSHAFT
(a) Inspect the camshaft for runout.
(1) Place the camshaft on V-blocks.
(2) Using a dial indicator, measure the circle runout
at the center journal.
Maximum circle runout:
0.03 mm (0.0012 in.)
If the circle runout is greater than the
maximum, replace the camshaft.
(b) Inspect the cam lobes.
(1) Using a micrometer, measure the cam lobe
height.
Standard cam lobe height:
47.306 to 47.406 mm (1.8624 to 1.8664 in.)
Minimum cam lobe height:
47.196 mm (1.8581 in.)
If the cam lobe height is less than the minimum,
replace the camshaft.
(c) Inspect the camshaft journals.
(1) Using a micrometer, measure the journal
diameter.
Standard journal diameter
If the journal diameter is not as specified, check
the oil clearance.
6. INSPECT NO. 2 CAMSHAFT
(a) Inspect the camshaft for runout.
(1) Place the camshaft on V-blocks.
(2) Using a dial indicator, measure the circle runout
at the center journal.
Maximum circle runout:
0.03 mm (0.0012 in.)
If the circle runout is greater than the
maximum, replace the No. 2 camshaft.

(b) Inspect the cam lobes.
(1) Using a micrometer, measure the cam lobe
height.
Standard cam lobe height:
45.983 to 46.083 mm (1.8104 to 1.8143 in.)
Minimum cam lobe height:
45.873 mm (1.8060 in.)
If the cam lobe height is less than the minimum,
replace the No. 2 camshaft.
(c) Inspect the camshaft journals.
(1) Using a micrometer, measure the journal
diameter.
Standard journal diameter
If the journal diameter is not as specified, check
the oil clearance.
7. INSPECT CAMSHAFT OIL CLEARANCE
(a) Clean the 10 bearing caps and camshaft journals.
(b) Place the 2 camshafts on the cylinder head.
(c) Lay a strip of Plastigage across each of the
camshaft journals.
(d) Install the 10 bearing caps (see page EM-84).
NOTICE:
Do not turn the camshaft.
(e) Remove the 10 bearing caps for the No. 2 camshaft
(see page EM-60) and camshaft (see page EM-61).
(f) Measure the Plastigage at its widest point.
Standard oil clearance
Maximum oil clearance
NOTICE:
Completely remove the Plastigage after the
measurement.
