LUG NUT TORQUE
SEQUENCE
The axle and wheel assemblies of your Lance Trailer
are designed differently than those on your car.
The overall size, weight and center of gravity of a
recreational vehicle subject the wheels to pressures
unique to trailering. During normal cornering, the tires
and wheels experience a considerable amount of
stress called “side-load”. Therefore, the lug nuts
on your recreational vehicle require periodic
re-torqueing.
These instructions will show you how to maintain
proper lug nut torque by following these important
steps:
1. Check torque before every trip.
2. Use proper tools.
3. Follow the appropriate star pattern sequence.
4. Torque lug nuts in the correct stages and follow-
up intervals after any wheel reinstallation.
For further information on these steps, you may want
to refer to the axle manufacturer’s owner manual.
Remember, torque is the amount of rotating force
applied to a fastener, such as a lug nut. Proper torque
of lug nuts can only be achieved by using a torque
wrench and a socket.
Note: Some wheel assemblies require an extension.
DO NOT USE a flexible extension. Also, DO NOT
USE a 4-way socket or any other type of wrench
which does not measure the actual pressure applied
to the lug nut.
Using Torque Wrenches
• Most torque wrenches are required to be set at “0”
when not in use to maintain calibration.
• Please refer to the manufacturer’s instructions for
further information on use and maintenance.
Setting Torque Value on a Dial Indicator Wrench:
1. Make sure your indicator needle is set to “0”.
2. As you apply clockwise pressure to the lug nut,
both needles will show the current amount of
torque being applied.
3. When you reach your desired torque value, stop
applying pressure and your indicator needle will
stay at the highest torque value reached.
Setting Torque Value on an Adjustable Dial
Wrench:
1. Unlock the handle and set the dial to your desired
torque value.
2. Lock the handle back in place.
3. As you apply clockwise pressure to the lug nut,
you will hear and audible “click” when the desired
torque wrench value is reached. Do not apply
further pressure once you hear the “click”.
Always remember:
• Check lug nut torque before every trip. Lance
recommends this maintenance procedure to
ensure proper torque has been applied to lug nuts
before heading out on the road.
• Lug nuts should be torqued to 110-120 ft/lbs.
• Always follow the appropriate star pattern as indi
-
cated to assure proper torque.
Pre-Trip Procedure:
1. Set your torque wrench to 110-120 ft/lbs.
2. Begin with the appropriate bolt for your wheel
(12 o’clock position for 8 and 6 hole wheels and
2 o’clock position for 5 hole wheels) and apply
torque to all lug nuts following the star pattern
indicated.
3. Complete the procedure on each wheel. Before
moving to each new wheel, be sure to verify your
preset torque wrench value.
WARNING
Under or over-torque of wheel lug nuts can
cause the wheel to separate from the axle
and could lead to property damage, serious
injury or loss of life.
After removing a wheel from your RV for any reason,
you must carefully follow a 2 step process:
1) Wheel Reinstallation
2) Follow-up
