Tires and Wheels<br />
Wheel Mounting and Fastening<br />
After the vehicle travels about 50 to 100 miles (80 to 160 km),<br />
wheel mountings “seat in” and will lose some initial torque.<br />
Check hub/wheel mountings after this initial period and<br />
retighten.<br />
Wheel Cap Nut Torque<br />
At the first scheduled lube interval, have all wheel cap nuts<br />
torqued to their specified value. See Table 13, “Wheel Cap<br />
Nut Torque,” Page 177 After that, check wheel cap nuts at<br />
least once a week. Contact an Authorized Service Center for<br />
information on the proper installation procedure for the<br />
wheels on your truck. This is a job you may not be able to do<br />
yourself if you do not have the right equipment.<br />
WARNING! Never use oil or grease on studs or<br />
nuts; improper torque readings will result, which<br />
could cause improper wheel clamping and could<br />
lead to a wheel failure resulting in an injury accident.<br />
Wheel Bearing Adjustment<br />
Preventive Maintenance<br />
For safe, reliable operation and adequate service life, your<br />
wheel bearings must be checked and adjusted properly at<br />
the recommended intervals. See Table 2, “Maintenance<br />
Schedule,” Page 113, and Table 3, “Maintenance Schedule,”<br />
Page 124. The person best equipped to do this is your Authorized<br />
Service Center's mechanic.<br />
Proper Torque and Sequence<br />
Proper wheel torque can best be obtained on level ground.<br />
Install lug nuts and finger-tighten in the numerical sequence<br />
as shown below, see “Crisscross Tightening Sequence” on<br />
page 179. This procedure will ensure that the wheel is drawn<br />
evenly against the hub. Torque each nut to the torque value<br />
listed in Table 13 on page 177.<br />
WARNING! Tighten wheel cap nuts properly. If<br />
they are not tightened properly, wheel nuts<br />
could eventually cause the wheel to become<br />
loose, to fail, and/or to come off while the vehicle<br />
is moving, possibly causing loss of control<br />
and/or serious personal injury or damage to the<br />
vehicle.<br />
