• 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 (if equipped) 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.
These dual rear wheels should be tightened as follows:
1. Tighten the wheel nuts in the num-
bered sequence to a snug fit.
2. Retighten the wheel nuts in the same
sequence to the torques listed in the
table. Go through the sequence a sec-
ond time to verify that specific torque
has been achieved. Retighten to
specifications at 100 miles (160 km)
and after 500 miles (800 km).
• It is recommended that wheel stud
nuts be kept torqued to specifications
at all times. Torque wheel stud nuts to
specifications at each lubrication
interval.
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.
