Is it only when the engine is under load (i.e. does it happen in 5th gear and not 2nd gear)?

I'm suspecting it may be your universal joint, but next time you fuel it up, try putting premium in it. If it is in fact detonation, that should make it go away. If it's still happening with premium fuel, and it is in fact coming from the back of the engine, my guess is that your universal joint is on the way out - which means it's only going to get worse.
