Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as
needed. Replace any components that have high effort
or excessive wear.
Do not lubricate accelerator and
cruise control cables.
Rear Axle Service
Check the gear lubricant level in the rear axle and add if
needed. See “Rear Axle” in the Index. A fluid loss may
indicate a problem. Check the axle and repair it if needed.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, 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.
