Chris,

I assume you mean wheel stud when you say lug.  These studs are pressed
into the flange, and if you have enough clearance behind it you can
drive it out, stick in a new one and use the lugnut to pull it into
place (usually with the wheel in place).  If you don't have enough
clearance between the flange and the backing plate behind it, you will
have to remove the flange.  Refer to the Bently or Haines for this
procedure.

Good luck!
