In 2006, the Ford Expedition has different caliper bolt sizes for the front brakes (9mm hex) and the rear brakes (7mm hex). When working on your car and adding or removing lug nuts, it's important to be careful not to damage them. If you tighten them too much, there's a risk of breaking or stripping them, especially if they are old or rusted. Stripped lug nuts will just spin in the socket, making it difficult to loosen them. In such cases, a mechanical press may be needed to push them out, but this could harm the wheel. If you break the bolts, you'll have to take out the wheel rotor and unscrew them from the back. These issues can be avoided by exercising caution while working on the car.
As mentioned, the hex refers to the bolt size, with the front brakes requiring a 9mm hex and the rear brakes needing a 7mm hex.
