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
numbered 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 second 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 Nut Torque
• 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 nuts should first be firmly seated against the wheel. The nuts should then
be tightened to recommended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening the nut opposite to the
nut just previously tightened until final torque is achieved. Recommended
torques are shown in the following chart.
