WHAT SHOULD BE DONE
Inspect the front and rear suspension and steering system for damaged, loose or missing parts,
signs of wear, or lack of lubrication. Inspect the power steering lines and hoses for pro\
per
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 an or could let exhaust fumes
into
the vehicle. See the Index under Engine Exhaust.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
-~~
Inspect the complete system. Inspect brake lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rot\
ors for surface condition. Inspect
other brake parts, including 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 the Ida under Brake System Warning Light. If your vehicle is
equipped with anti-lock brakes and the anti-lock brake system w\
arning light
stays on, comes on
or flashes, something may be wrong with the anti-lock brake system. See the
Index under Anti-
Lock Brake System Warning Light.
