Now and then, make sure all your belts, buckles, latch plates, retractors, anchorages and
reminder systems are working properly. Look for any loose parts or damage. If
you see anything
that might keep a restraint system from doing its job, have it repaired.
Inspect the froht 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 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

WHAT SHOULD BE DONE
Check the gear lubricant level and add if needed. See “Rear Axle” and “Four-Wheel Drive” in
the Index. A fluid loss may indicate a problem. Check the system(s), and repair the system(s) if
needed. Refer to “Scheduled Maintenance Services,” earlier in
this part, to determine when to
change the lubricant.
Inspect the complete system. Inspect brake lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Also
inspect
drum brake linings for 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 serv-
iced. Also,
if the brake system warning light stays on or comes on, something may be wrong
with either the regular or rear wheel anti-lock brake system, or both systems. See “Brake System
Warning Light” in the Index.
Check clutch pedal free travel and adjust
as necessary. See “Clutch Adjustment” in the Index. ..
