I've been in the process of rebuilding my entire suspension, and you just need to replace the whole bushing, bolt, etc. There's going to be a couple of different ways to do it.
1. Push it out
2. Cut it out
3. Burn it out
Honestly, burning it out is going to be the least desireable, but it's what's ever going to be easiest. I wouldn't take it to a shop though, b/c you'll just feel bad spending the money later
