lug nut may be a size that does not hold the wheel securely against
the hub, even when fully tightened. Be certain a replacement lug
nut is an exact match for the original.
Ensuring that lug nuts on trailer wheels are tight and properly
torqued is an important responsibility for maintaining your trailer
in a safe operating condition. Inadequate and/or inappropriate lug
nut torque (tightness) is a major reason that lug nuts can loosen
during use. Loose lug nuts can rapidly lead to a wheel separation
from the hub, with potentially serious safety consequences.
Check the lug nut tightness often, especially during the first few
hundred miles of the trailer’s use. You should always check the
torque prior to beginning any long trip and every time a wheel is
removed and reset.
You must use a torque wrench to accurately indicate the amount
of torque that you are applying to the lug nut. Four-way wrenches,
ratchets, and similar tools can be useful for short-term emergency
repairs but are not appropriate tools for accurately checking lug
nut torque.
Keep a record of the date and approximate mileage when the
lug nut torque is checked. Note any lug nut(s) that lost torque.
Investigate the reason(s) if the lug nut torque is not maintained
over more than one retightening because this can be indicative
of a possible problem with the lug nuts, nut studs, wheels and/or
hubs and that should be corrected.
Contact an authorized MasterCraft dealer immediately if any
persistent lug nut loosening (or any other lug, wheel or axle
problem) occurs.
In the event of a wheel separating from the trailer during use,
notify an authorized MasterCraft dealer. Seek prompt professional
assistance in assessing the trailer and its gear, and retain but
do not reuse involved lug nuts, wheels and studs. Do not repair
or service the trailer yourself. Instead, call a trained, authorized
MasterCraft service technician.
Use the following pattern to tighten lug nuts. On first torquing
pass tighten to 45 lb.-ft. On second pass tighten to 70 lb.-ft.
On third pass tighten to 90 lb.-ft. On fourth pass tighten to a
reading between 110 lb.-ft. and 120 lb.-ft. Follow the pattern below.
