That could well be what it is. A lot of times that's what causes it. But to come on here and flat out tell somebody what it is for sure is flippin stupid. Yall don't know any more than the man in the moon what his problem is cause ain't none of yall put a damn mic on it. Bad Demon, I would recommend since you've broken more than one, that you check it yourself or have it done. Yeah, it's a pain in the butt, but sounds like that might be it. No way to diagnose one over the computer for sure. BUT, as per my original recommendation, runnin crap *** auto parts store parts ain't the way to fly. Even after you determine what the problem is, I recommend much better parts than from Autozone or the like. But as said....IF it's out of alignment, the best parts in the world are for naught. I would certainly check it out. I've seen junk aftermarket converters have the bolt pattern welded crooked. Imagine that.It could be several things. No way to know til it's checked out.
