Lug Nut Torquing

Trailer wheels must carry much
higher loads per wheel than passenger car or truck wheels. Each
wheel may carry 1000 pounds and higher.
When going around corners, especially on slow, tight turns, the
wheels are subject to very strong side loads. This tends to flex
the wheel and gradually loosen the wheel nuts. Although the
materials and manufacturing methods are maximized for this kind
of service, these extra loads can cause stress, which can result
in flexing and loosening of lug nuts.
Before each trip and any time
a wheel is replaced, be sure
to tighten the wheel nuts,
following the lug-pattern
sequence shown here. If the
wheel was replaced, check
the torque every 10, 25 and
50 miles.
If you notice wheel wobbling
or hear a rattling sound
coming from a wheel, a lug
nut may have come loose. This problem is usually caused by
improper tightening or by faulty or damaged lug bolt threads.
If suspicious of a loose lug nut, safely stop vehicle as soon as
possible. Put up warning devices. Tighten all lug nuts to the
specified torque using a torque wrench. If stud threads are
damaged or faulty, get professional service help.
NOTE
Use a torque wrench to tighten lug nuts.
Tightening by hand or with an impact wrench is not
recommended. Torque Aluminum Wheels to 110 ft.
lbs and Steel Wheels to 100 ft. lbs..

Spare Tire Carrier

The Nest spare tire is stored under the front of the trailer. The
front handle of the tire carrier is a 1-in. tube protruding out from
under the frame on the curbside. It is secured by a bracket and
bolt along the inside of the frame rail. Removing the bolts allows
the front on the tire carrier to be lowered and the spare tire to be
removed.
WARNING
The spare tire carrier is designed to carry an
undamaged tire and rim assembly of the type and
size specified for the trailer. Never place a severely
damaged wheel assembly with a partial tire, or a
rim only, in the carrier.

Brakes

Due to normal brake lining wear, the brakes and the controller
setting should be checked every six months or 10,000 miles,
whichever comes first.

Breakaway Switch

To prevent corrosion within the breakaway switch, pull the
plunger pin out and spray the inside of the switch through the pin
insertion hole with an electric contact cleaner. Applying a drop
of light household oil on the plunger pin and the groove near the
base of the pin will allow the pin to operate freely. Immediately
reinsert pin. Perform these procedures every 90 days.
CAUTION
Allow no more than 20 to 30 seconds of plunger
pin separation from switch as damage to brake
magnets may occur.
For more information regarding the Breakaway Switch refer back
to Section 7-2.
