ISSUE:
The use of a power impact wrench to install wheel nuts provides minimal torque control. Undertightening may allow the lug nuts to loosen,
and can result in the wheel separating from the vehicle. Overtightening of wheel nuts may cause brake rotor distortion that could result in a
brake shudder. Overtightening may cause distortion of the wheel. This can result in a change in the diameter of the center (axle) hole and
make it difficult to remove from the axle it is mounted on or difficult or impossible to install on another axle with a smaller center hole
diameter.
ACTION:
Use a manual torque wrench to tighten wheel nuts. Refer to the approriate Shop Manual for specific torque values.
