one of my lug nuts is broken, if i buy the disc will it come with the lug stud in there already or is there a hub?
stud's you can replace the stud buy removeing rotor and drivig the stud downward. to install start stud in whole with a few taps .then iinstall a few washers and tighten nut till stud is flush with rotor backing.total cost a couple bucs.
you can buy the an individual stud for about a buck... a new rotor does come with new studs, but if the rotor is good... just buy a stud. Take a lug nut with you to make sure the lug nut behind the counter doesnt give you the wrong part.
