Wheel Nuts

All wheel nuts should be tightened occasionally to eliminate the possibility of wheel
studs being sheared or the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles/kilometers of operation to allow
the wheel nuts to become properly set. All wheel nuts should first be firmly seated
against the wheel. The wheel nuts should then be tightened to recommended torque.
Tighten the wheel nuts to final torque in increments. Progress around the bolt circle,
tightening the wheel nut opposite to the wheel nut just previously tightened until final
torque is achieved. Recommended torques are shown in the following chart.

8-Stud — Dual Rear Wheels
• Dual wheels are flat-mounted and center-piloted. The lug nuts are a two-piece
assembly. When the tires are being rotated or replaced, clean these lug nuts and
add two drops of oil at the interface between the hex and the washer.
• Slots in the wheels will assist in prop-
erly orienting the inner and outer
wheels. Align these slots when assem-
bling the wheels for best access to the
tire valve on the inner wheel. The tires
of both dual wheels must be com-
pletely off the ground when tightening,
to ensure wheel centering and maxi-
mum wheel clamping.
• Dual wheel models require a special
heavy-duty lug nut tightening adapter
(included with the vehicle) to correctly
tighten the lug nuts. Also, when it is
necessary to remove and install dual rear wheels, use a proper vehicle lifting
device.
NOTE:
When installing a spare tire as part of a dual rear wheel end combination, the tire
diameter of the two individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front location. The correct direction
of rotation for dual tire installations must also be observed.
