Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the fas-
teners matched to the cone angle of the wheel. Proper pro-
cedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure 36. DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 9.
3. Check to see if the lug nuts are tight after the first 10, 25
and 50 miles of driving and before each tow thereafter.
Wheel Rims
If the trailer has been struck, or impacted, on or near the
wheels, or if the trailer has struck a curb, inspect the rims for
damage (i.e. being out of round); and replace any damaged
wheel. Inspect the wheels for damage every year, even if no
obvious impact has occurred.
Wheels, Bearings and Lug Nuts
A loose, worn or damaged wheel bearing is the most
common cause of brakes that grab.
To check wheel bearings, jack trailer and check wheels for
side-to-side looseness. If the wheels are loose, or spin with
a wobble, the bearings must be serviced or replaced. Check
inflation pressure weekly during use to insure the maximum
tire life and tread wear.Most trailer axles are built with sealed
bearings that are not serviceable. Sealed bearings must be
replacedas complete units.
ALWAYS
wear safety glasses when
removing or installing force fitted parts
DO NOT attemp to repair or modify a
wheel. DO NOT install an inner-tube to
correct a leak through through the rim. If
the rim is cracked, the air pressure in the inner tube may
cause pieces of the rim to explode (break off) with great
force and cause serious eye or bodily injury.
WARNING - Flying Objects
NOTE
TIRE SAFETY
Lug nuts are prone to loosen after initial installation, which
can lead to death or serious injury. Check all wheel lug
nuts periodically.
WARNING - Lug Nut Inspection
NEVER! use an pneumatic
air gun to tighten wheel lug
nuts.
Over-tightening lug nuts will result in breaking the studs
or permanently deforming the mounting stud holes in the
wheels.
WARNING - Lug Nut Tightening
