ing against wheel face. Hex size is 33 mm (same as 1-

•
Inner and outer cap nuts

fers on wheels. Inner nut has 13/16 in. square end.
Outer nut has 1-1/2 in. hex.
WARNING!
Do not mismatch wheel compo-
nents. Equipment that does not exactly match
original specifications or that is mismatched
could cause the wheels to break and separate
from the vehicle causing death or personal
injury. Each mounting system is engineered for
use only with its correct mating part. Be sure
properly matched components are used for each
type of mounting.
Wheel Cap Nut Torque
At the first 100 miles, have all wheel cap nuts torqued to
their specified value. After that, check wheel cap nuts at
least once a week. Contact the Service Department at
your dealership for information on the proper installation
procedure for the wheels on your truck. This is a job you
may not be able to do yourself. You need the right torquing
equipment to do it.
WARNING!
• Never use oil or grease on studs or nuts;
improper torque readings will result, which
could cause improper wheel clamping and
could lead to a wheel failure resulting in an
accident causing death or personal injury.
• Tighten wheel cap nuts properly. If they are
not tightened properly, wheel nuts could even-
tually cause the wheel to become loose, to
fail, and/or to come off while the vehicle is
moving, possibly causing loss of control if the
vehicle and death, serious personal injury or
damage to the vehicle.
Wheel Bearing Adjustment
For safe, reliable operation and adequate service life, your
wheel bearings must be checked and adjusted properly.
The person best equipped to do this is your authorized
dealer’s service mechanic.
