Your front wheel hub is one piece with the rotor. You will need NAPA part number 86446. They also have a second line that is a little less expensive. You will also need a br5 inner wheel bearing and a br3 outer bearing, along with a 19784 seal. Make sure you pack the bearings properly. ! Inspect the spindle VERY CARFULLY as this may be damaged by the assembly coming off. If so, replace the spindle as well. Also, make sure you inspect the other side to avoid it from coming off.
Hope this helps.
