Inspect the front and rear suspension and

lubrication. Inspect the power steering
lines and hoses for proper hookup,
binding, leaks, cracks, chafing, etc.
Clean and
then inspect the drive axle
boot seals
for damage, tears or leakage.
Replace seals if necessary.
Inspect the complete exhaust system.
Inspect the body near the exhaust
system. Look for broken, damaged,
missing or out-of-position parts as
well
as open seams, holes, loose connections,
or other conditions which could cause a
heat build-up
in the floor pan or could let
exhaust fumes into the vehicle. See
“Engine Exhaust”
in the Index.
Inspect the throttle linkage for
interference
or binding, and for
damaged
or missing parts. Replace

brake lines and hoses for proper
hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition.

wear and cracks. Inspect other brake
parts, including drums, wheel
cylinders, calipers, parking brake, etc.
Check parking brake adjustment.
You
may need to have your brakes inspected
more often if your driving habits or
conditions result
in frequent braking.
NOTE: A low brake fluid level can
indicate worn disc brake pads which
may need
to be serviced, Also, if the
brake system warning
light stays on or
comes on, something may be wrong
with the brake system. See “Brake
System Warning Light”
in the Index. If
your anti-lock brake system warning
light stays on, comes on
or flashes,
something may be wrong with
the
anti-lock brake system. See “Anti-Lock
Brake System Warning Light”
in the
Index.
