4. Steering Linkage: Inspect the connecting
links, arms, and rods for worn, damaged,
loose, or missing components.
5. Tire: Check the tread depth and tire
inflation. Note if the tread is evenly
worn. Minimum tread depth is 3 mm
(4/32 in) on all tires. Look for cuts or
other damage to the tread or sidewalls.
See if the valve caps and stems are
missing, broken, or damaged.
6. Brake Pads and Rotor: With the brakes
released, check to see that the brake
linings (where visible) are not worn
excessively thin, less than 6 mm
(0.25 in), or contaminated by lubricant.
Where visible, check the disc brake
caliper wear indicator to see that the
brake pads/rotor are not worn
excessively.
7. Hub: Check for obvious leaks on the
outboard or inboard sides of the wheel.
Verify that the oil level in the hub is
correct.
8. Wheel and Lug Nuts: Check for damaged
or bent wheel. Check to see that all the
lug nuts are present and not loose. Look
for rust trails around the nuts. Ensure
that no cracks or damage are present at
the wheel mount holes.
9. Spring Suspension: Check the condition
of the spring for cracks, breaks,
or shifting. Inspect the spring hanger
fasteners, shackles, U-bolts, and nuts for
wear, damage, and tightness.

Service and Maintenance
Warning (Continued)
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
2. Coolant Level: Do not remove the
pressure cap unless the coolant is cool.
Ensure the fluid level, if cold, is within
the minimum and maximum fluid level
range as marked on the plastic
translucent reservoir. If hot, the fluid
level must be above the minimum mark,
but below the fill neck.
3. Air Cleaner: Check the air cleaner housing
and hoses for loose connections or
damage. For element replacement, see
Engine Air Cleaner/Filter 0 276.
4. Radiator and Charge Air Cooler: Check for
loose mounting and damage. Inspect the
condition of all the hoses for damage,
cracks, and leaks. Inspect for foreign
material on the face of the cooling
package. Carefully brush away the
collected materials without bending the
cooling fins to maintain proper airflow
through the cooling package.
