I say use heat as a last resort since most people are not used to using torches. Lots of things can go wrong if used improperly LOL, there are plenty rubber parts in the area, and sometimes brake fluids, oil and gas residues can also create interesting surprises :)

Too little heat and nothing happens, too much heat and you're messing with the integrity of the metal. Using heat is a great tool to get stuff apart but you have to know what you're doing, so I always say, IF ALL ELSE FAILS, use heat and a hammer.
