Default 96 Bonneville-Cracked rt rear control arm

I noticed the rear of my car squirming when I went over expansion joints yesterday. So looked under the car and the right hand lower rear control arm is cracked pretty badly. I have a donor car so I started to take mine off today. I got it down to the point that I am trying to get the bolts out of the bushings and I am having a hell of a time.

Has anyone replaced their control arm bushings and if so, how in the heck did you get the bolts out of the bushings? I tryed pushing them out with an air chisel with pusher type of insert in the tool and it neither bolt wants to budge. Also, the bolt on the front side of the arm looks like it might not come out without dropping the gas tank-I hope that it is not so. Any ideas/

Thanks
Andy

Mine broke. Its a Real PITA to get those bolts out sometimes. I had to Torch mine. Heating them up. trying to break them loose. Then spraying them with some PB Blaster.

Its hard, but can be done.

Where you able to save the bolts or did you have to cut them off flush to get the arm off? Did you have to drop the tank?

Thanks

Drop the tank. no. you dont have to do that.

I did not have to cut the bolts. just kept working them until they came undone.

Lots a PB Blaster, and a Good Torch will do the trick. i mean not the huge ones like at shops. those would work the best. but all you really need is a good Propane one or the Yellow bottle ones. i forget the gas name on those.


also, do you have a good LONG breaker bar? if not. go get a good 1/2 drive one thats like 24" long.

I got them out today. I went and bought a bottle of MAPP gas and hit them with an air chisel to push them out. Thanks for your tips and suggestions.
