I am working on my integra's front suspension, but 3 bolts are rust welded. My impact gun managed to get one off, but the others wont budge. I hit them so much that the impact bit got too hot to the touch. Sprayed with penetrating fluid, hit it with a hammer etc.
My only other option is heat, but the problem is, that it's a wheel well and it traps heat, not to mention there is a brake hose which is very close to the area I will be heating.
How can I contain my propane torch heat to this specific bolt without damaging other areas?
No, I cannot, not enough vertical space for that. I have managed to remove the lower bolt on one side because it was greased before bolted in and I have to remobe both bolts to remove the strut.
To get the strut out, you also have to unbolt the upper control arm at the ball joint. I had this car for 16 years and have done it this way several times.
Edit: also unbolt the sway bar if have not done so.
