Wheel Cap Nut Torque
At the first scheduled lube interval,
have all wheel cap nuts torqued to
their specified value listed in Wheel
Cap Nut Torque on page 5-149. After
that, check wheel cap nuts at least
once a week. Contact an authorized
dealer 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.
