It is recommended that wheel stud nuts
be kept torqued to specifications at all
times. Torque wheel stud nuts to specifi-
cations at each lubrication interval.
Wheel Nuts
All wheel nuts should be tightened occa-
sionally 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 op-
eration 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:
Disc Wheels
Nut Type Stud Size Hex Size Torque Ft Lbs Torque
Newton Meters
Cone M14 x 1.5 22 mm 130 176
Flanged M14 x 1.5 22 mm 140 190
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builders Guide for information on stowing your spare tire (if
equipped).
HOISTING
A conventional floor jack may be used at the jacking locations. Refer to the graphics
that show jacking locations. However, a floor jack or frame hoist must never be used
on any other parts of the underbody.
CAUTION!
Never use a floor jack directly under the differential housing of a loaded truck or
damage to your vehicle may result.
