ON±VEHICLE WHEEL BALANCING
NOTICE:
1. When doing on±vehicle wheel balancing on a fulltime 4WD
vehicle, to prevent the wheels from rotating at different
speeds or in different directions from each other (which
could lead to damage to the center differential or trans-
axle gears), always be sure to observe the following pre-
cautions:
(1) A11 four wheels should be jacked up, completely clear
of the ground.
(2) The wheels should be driven by both the engine and
the wheel balancer.
(3) The center differential control switch should be in the
OFF condition.
(4) The mode select lever on the transaxle should be in
the LOCK position.
(5) The parking brake lever should be fully released.
(6) None of the brakes should be allowed to drag.
2. Avoid sudden acceleration, deceleration and braking.
3. Carry out the wheel balancing with the transmission in D
range.
1. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
OFF
(1) Check that the center differential control indicator light
goes off.
(2) Further check that hydraulic multiplate clutch control of
the center differential is in OFF condition.

BRAKES
13. INSPECT BRAKE LINE PIPES AND HOSES
HINT: Check in a well lighted area. Check the entire circum-
ference and length of the brake hoses using a mirror
as required. Turn the front wheels fully right or left before
checking the front brake.
(a) Check all brake lines and hoses for:
wDamage
wWear
wDeformation
wCracks
wCorrosion
wLeaks
wBends
wTwists
(b) Check all clamps for tightness and connections for
leakage.
(c) Check that the hoses and lines are clear of sharp
edges, moving parts and the exhaust system.
(d) Check that the lines installed in grommets pass through
the center of the grommets. 10. INSPECT FUEL LINES AND CONNECTIONS
Visually check the fuel lines for cracks, leakage, loose con-
nections, deformation or tank band looseness.
11. INSPECT EXHAUST PIPES AND MOUNTINGS
Visually check the pipes, hangers and connections for se-
vere corrosion, leaks or damage.
12. ADJUST VALVE CLEARANCE
3S±FE (See page EM±11)
2VZ±FE (See page EM±15)
Valve clearance (Cold):
3S±FE Intake 0.19 ± 0.29 mm
(0.007 ± 0.011 in.)
Exhaust 0.28 0.38 mm
(0.011 0.015 in.)
2VZ±FE Intake 0.13 ± 0.23 mm
(0.005 ± 0.009 in.)
Exhaust 0.27 ± 0.37 mm
(0.011 ± 0.015 in.)
± MAINTENANCEMaintenance OperationsMA±7

(d) Settle the parking brake shoes and drum. When per-
forming the road test in item 23, do the following:
wDrive the vehicle at approx. 50 km/h (30 mph) on a safe, lev-
el and dry road.
wWith the parking brake release button pushed in, pull on the
lever with 9 kg (20 Ib, 88 N) of force.
wDrive the vehicle for approx. m (1 /4 mile) in this condition.
wRepeat this procedure 2 or 3 times.
wCheck parking lever travel.
If necessary, adjust the parking brake.
15. INSPECT BRAKE PADS AND DISCS
Front (See page BR±26)
Rear (See page BR±42)
(a) Check the thickness of the disc brake pads and check
for irregular wear.
Minimum pad thickness: 1.0 mm (0.039 in.)
HINT: If a squealing or scraping noise comes from the brake
during driving, check the pad wear indicator to see if it is
contacting the disc rotor. If so, the disc pad should be re-
placed.
Minimum disc thickness:
Front 24.0 mm (0.945 in.)
Rear 9.0 mm (0.354 in.)
Maximum disc runout:
Front 0.07 mm (0.0028 in.)
Rear 0.15 mm (0.0059 in.)
CHASSIS
16. INSPECT STEERING LINKAGE
(a) Check the steering wheel freeplay.
Maximum steering wheel freeplay: 30 mm (1.18 in.)
With the vehicle stopped and pointed straight ahead, rock
the steering wheel gently back and forth with light fin-
ger pressure. 14. INSPECT BRAKE LININGS AND DRUMS
Drum brake (See page BR±31)
Disc brake (See page BR±47)
(a) Check the lining±to±drums contact condition and lin-
ing wear.
Minimum lining thickness: 1.0 mm (0.0039 in.)
(b) Check the brake drums for scoring or wear.
Maximum drum inside diameter:
Drum brake 230.6 mm (9.079 in.)
Disc brake 171.0 mm (6.732 in.)
(c) Clean the brake parts with a damp cloth.
HINT: Do not use compressed air to clean the brake parts.
