I've tried the breaker bar method, it worked on the passenger side but the driver side is stubborn. I stuck a monkey wrench in there because the breaker bar would slip out, still wouldn't work. I tried putting the jack on the monkey wrench to pry it apart, didn't work either; It just jacked the car up. Only thing I haven't tried is using a jaw puller; mainly because I have a 6" 3-jaw puller but need a 2-jaw one. Do you think heat will help get it loose or simply just using a jaw puller will work?
