Broken Wheel Bolts

[Denis]

  Heat around the bolt and put penetrating oil.
  Let it cool then repeat it. It expand and unjamm the bolt, at least it help to remove it easier.
  Punch the center and make a hole trought the bolt. 1/4 inch

  Use a tool to unscrew it (i dont know the name in english) 
  I did many times but not on wheels.

  If it still hard, heat again around the bolt, not the bolt, add penet oil......

  The wheel must be got a good shoot to it  to broke 2 bolts ?

    Anybody faced this before:
    http://www.pbase.com/kneale_brownson/image/39122017  Those holes you can't
    see through have broken-off ends of wheel bolts in them.   The broken bolts
    are at    http://www.pbase.com/kneale_brownson/image/39121870

    I was wondering why I was hearing a strange noise.

    The Bolts were tightened by hand and torqued with a torque wrench, a
    process I've done many, many times.   I checked bolt tightness again after
    about 100 miles of driving.   Nothing was loose.

    Any guesses as to why the bolts broke?

    Any suggestions for removing the broken off stuff?  Since taking the pix I
    have bathed them in Kroil.  I have a set of those reverse drill bits with
    extractors.  Do I need to be accurate in centering one of the bits?  The
    exposed surfaces are uneven.  Should I use the largest size I have?
