Went back and reread your first post. Every engine Ive pulled apart and rebuilt, there is a crankshaft behind the harmonic balancer not a balance shaft as your "mechanic" told you. You may want to look for a new mechanic as I would be questioning this guys skills.
Yeah he printed me out an engine diagram and everything and showed me the balance shaft sleeve connected to the HB, then it hit me the other day that I should check into it myself and looked for pics online, it looked totally different. So I asked ford for an engine diagram and I immediately recognized the part, and it sit above the crankshaft, and they said it would take an INCREDIBLE amount of force to damage or crack that piece.
Thanks man I will let you know! And yes I'm pretty sure (for the most part) that its just the harmonic balancer because before I replaced it the car shook noticeably but when the new one was installed it was bad enough that it shook the snow off my car. So I'm thinking the correct balancer will have it running good again (hopefully!) If not then I'm more than happy to work out a deal with you
