Electrical System Inspections; Accessory Feed Connections; Suspension Inspection - Ford Low Cab Forward Truck Owner's Manual

Maintenance and Specifications

ELECTRICAL SYSTEM INSPECTIONS

Periodically inspect electrical connectors on the outside of the cab, on
the engine and frame for corrosion and tightness. Exposed terminals
such as the fuel sender, cranking motor, alternator and feed-through
studs should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft XG-3, or equivalent. This should include the ground
cable connector for batteries, engine and cab.

Accessory feed connections

Vehicle electrical systems are complex and often include electronic
components such as engine and transmission controls, instrument panels,
ABS, etc. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. Refer to
the Electrical Circuit Diagram Manuals, available from your vehicle's
manufacturer, to ensure that any additional body lights and accessories
are connected to circuits that are both appropriate and not overloaded.
No modification should be made to any vehicle control system without
first contacting your dealer.

SUSPENSION INSPECTION

Periodically:
• Check condition of spring leaves for evidence of fatigue, bending or
breaks.
• Check condition of suspension mounting brackets and bushings.
• Check that torque rod mounting fasteners are tight.
• Check to be sure the suspension alignment is maintained at all time.
• Check U-bolts after the chassis has been operating under load for
1,000 miles (1,600 km) or six months, whichever comes first, the
U-Bolt nuts must be re-torqued. The U-Bolt nuts thereafter must be
re-torqued every 36,000 miles (58,000 km). The U-Bolt and nut
threads and seats should be cleaned and lubricated to ensure a "like
new" condition when re-torquing.
Note: See the U-Bolt Nut Torque chart in this chapter.
