<strong>01. </strong>From the factory, the F-150 2WD uses a cast-iron one-piece wheel hub/rotor. Whenever the rotor is a problem, you get to buy the whole assembly or deal with pressing in unit bearings. It’s a cheap factory solution but a poor choice for serviceability over the life of the truck. The big spindle nuts are not reusable and run $11 to $25 each, depending on where you purchase them.
