I know this is perhaps a long shot, but don't discount it being your CV half shaft. I have just replaced the driver's side at 170 000 KM. Started off as a grinding noise that oscilated approaching a stop. As the week went on, progressed to a steady noise at all speeds under transmission load (manual transmission). Keep tabs on it and see if it grows worse.
Failing that, could very well be your sway bar bushings. Recently replaced my sway bar end links and will now be replacing the bushings as well. That sounds more like a creaking/groan when stopping. You can simulate the noise by pushing down on the front end while stopped - open the hood, the noise will appear to be coming from behind the engine. If it's this, I wouldn't sweat it, it's just noise - turn up the radio - and head to Rock Auto when you get a chance! Under $5.00 a set
