Wheels and Hubs
Because they are often ex-
posed to water, trailer wheels
and tires require more atten-
tion than the wheels on a fam-
ily vehicle. e three major
items to check are lug nuts,
lubrication and tire pressure.
Maintain the proper torque on
the lug nuts attached to the
wheel bolts. Failure to do so
may result in serious injury
or property damage. An au-
thorized MasterCraft dealer
can provide the proper torque
specications (measured in
foot-pounds).
Keep the wheel bearings lubricated. Inspect the wheel bearings for proper lu-
brication before each use. Failure to do so may cause wheel failure and possible
wheel loss, which may result in serious injury or death and/or property damage.
As part of the regular maintenance, keep the axle assembly properly lubri-
cated. is procedure is best performed by your MasterCraft dealer. e fill plug
in the hub nose must be removed so that 50-weight oil can be added. “Never-
seize compound” should be applied to the fill plug, which is then reinstalled and
torqued to 7 ft-lbs. If at any time the oil in the hub appears milky, the system
must be serviced immediately.
Lug Nuts or Wheel Bolts
Loose wheel mounting nuts (lug nuts) can cause more than just an annoying
wheel wobble—it’s possible to lose a wheel. Before each trip check for loose or
missing lug nuts/wheel bolts.
