Rear of vehicle
Air/Electric linesVerify air hoses and electrical line insulation are
not cut, cracked, chafed or worn. Listen for
audible air leaks. Verify air and electrical lines are
not tangled, crimped or pinched or being dragged
against any truck parts. None of the air or
electrical line should be spliced or taped. Inspect
for corrosion on pins and in electrical sockets to
ensure continuity and reduced heat build-up
potential.
Deck plateVerify deck plate is clean, securely bolted to the
frame and clear of loose objects.
Signal/Brake
lightsVerify both brake lights illuminate when the
brake pedal is applied, each signal flashes and
that four-way flashers work properly.
Lights, reflectorsVerify all lights illuminate and are clean,
reflectors are clean, unbroken and of proper color
(red on rear, amber elsewhere) and that running
lights are also clean and unbroken. Rear running
lights must be inspected separately from signal,
flasher and brake lights.
Tractor - coupling system
Mounting boltsInspect for loose or missing mounting brackets,
clamps, bolts or nuts. Both fifth-wheel and slide
mounting must be solidly attached.
PlatformInspect for cracks or breaks in the platform
structure.
Safety latchVerify safety latch is engaged.
Release armVerify safety latch is in the engaged position and
that any safety latch is in place.
Kingpin/ApronVerify kingpin is not bent or worn, the apron lies
flat on the fifth-wheel skid plate and that the
visible part of the apron is not bent, worn,
cracked or broken.

All tires with Steel Carcass Plies (if equipped):
This type of tire utilizes steel cords in the sidewalls. As such, they
cannot be treated like normal light truck tires. Tire service, including
adjusting the air pressure, must be performed by personnel trained,
supervised and equipped according to Federal Occupational Safety and
Health Administration (OSHA) regulations. For example, during any
procedure involving tire inflation, the technician or individual must
utilize a remote inflation device, and ensure that all persons are clear of
the trajectory area.
WARNING:An inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and
property.

Rotating tires from one wheel position to another is a way often used to
even out many types of irregular wear or to avoid it altogether. Some of
the more effective tire rotation programs are:
•Steer tires that have developed some type of irregular wear pattern
can be rotated to drive axles if rib tires are being used on all wheel
positions. Applying steer tires to a drive position often cleans them
and they can be moved back to the steer axles or run out to re-tread
stage on the rear axle.
•Another rotation possibility for fleets with rib tires in all wheel
positions is to break in the new steer tires in the drive axle positions,
then move them to steer axles. This wears away tread rubber
relatively quickly in the early life of a tire when it is most likely to
develop an unusual wear pattern.
•Drive axle tires may be placed on the other end of the same axle so
that direction of rotation is reversed. This is often helpful if a heel and
toe or alternate lug wear pattern has developed.
Irregular wear can be minimized by:
•Using the right inflation pressure for the load being carried.
•Maintaining proper front wheel alignment -especially toe-in-to
specifications.
•Maintaining proper tire and wheel balance.
•Maintaining shock absorbers and suspension components.
Use of tire chains
Refer to chain manufacturer’s recommendation for correct tire chain
usage, installation and removal.
