    Normal broken bolt removal procedures should do it.

    1 lots of penitrating oil (pb blaster seems to work fastest, WD40 or Fluid Film will also work but take time)
    2 LEFT HAND DRILL BITS centered at LOW RPM to drill it out, often the heat from drilling plus the penitrating oil will unscrew the bolt as your drilling.
    3 if no left hand bits use a broken bolt extractor/drill combo (sears has them)
    4 you can use a normal drill bit again slowly and centered then a normal extractor (easy-out) but don;t break the easy out or the drill bit.

    5 heat the bolt and arm with a torch- heat will expand and crack the rust out tending to free the bolt, may be necessary for th easy-out to work.

    last resort is drill it out completely with a drill that it slightly undersized from the threads (avoiding t5he threads)

    Always chase the threads with a tap after removeing a broken bolt to clean them- if you drill close to thread size you can probabily save the threads and avoid having to retap it larger.

    Just learned a new one- vacuum motor on my front axle died- 2 bolts snapped removing the cover. If the bolts is sticking out enough get a normal nut (hex nut) that will fit over the threads (not screw on, slide over- 7/16 nut for a 1/4 bolt) and WELD it on to the exposed bolt. Mig works best for this. The heat helps to break it free and the nut gives you something to turn- don;t use vicegrips unless it's a last resort- they usually break the bolt worse.
