As for getting them out, i find that if they're in an area you can get a torch, even a mapp torch, some heat always works miracles. Heat them up good, when you think they're hot enough, heat them a bit more. They'll usually back out then. JUST BE AWARE OF THE AREA SURROUNDING THEM FOR POTENTIAL FLAMMABLES!!! ie. grease, rubber, plastic, fuel etc.,etc.
Torque wrench no. Heat Yes.
