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 proper
hookup, binding, leaks, cracks, chafing, etc. Clean and then in\
spect 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 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 hooku\
p, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors 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
Idex under Brake System Warning Light. If your vehicle is equipped with
anti-lock brakes and the anti-lock brake system warning light stays on, comes on or flashes,
something may be wrong with the anti-lock brake system. See the
Index under Anti-Lock Brake
