Im in a spot of bother with trying to remove one of my trailing arms.. got one off fine (well as fine as it goes after 20 years of being on!).. But my other one, well.. the bolt snapped on one of them and that bolt wont hammer+punch out, and on the other side the nut came off fine, but the bolt doesn't really turn so I assume its well.. stuck in the bush.
Now ive beated then bolts with my best hammer and they are winning! Can I use a heat gun or small blow torch to heat up the entire lot and "soften" the bushes into letting me get the bolts out?
- I plan on replacing the bushes and power-coating the arms.. thats why i was removing them.
Any advice would be great received

Many Thanks,
Matt.
