TIRES AND WHEEL Wheel Mounting and Fastening WARNING! Wheel Cap Nut Torque 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 acci- dent. Failure to comply may result in death, personal injury, equipment or property damage. At the first scheduled lube interval, have all wheel cap nuts torqued to their specified value listed in Wheel Cap Nut Torque chart below. 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. After the vehicle travels about 50 to 100 miles (80 to 160 km), wheel mountings seat in and will lose some initial torque. Check hub/wheel mountings after this initial period and retighten.
