My buddy has this 4.0l Explorer 4x4 auto and it keeps breaking flywheels! It's just a daily driver and is stock, no big horspower or anything. We went to put a new fly wheel in it, bolted everything up and the now the damn thing won't even turn over. I mean we put a breaker bar on the crank and you can't turn the motor over, so we unbolted the tranny and then every thing turns over...WTF! U^$$^@#%^@&*^@#R%*(^) sorry...Any ideas?
