DYE have Grinding Noise in left rear with high rpm?

Question

Hi all,

I was driving along the motorway today and i noticed when I've pushed the engine to higher rpm's I start hearing a grinding noise towards my left rear side. I haven't done any servicing yet (just bought it second hand) but I am scared if something is really wrong with it.

Anyone know what it could be? I really enjoyed driving her today for the first time and I don't want her to suffer any irreparable damage :(

EDIT: Model is NB 2004 (base edition)

Any damage is repairable ;)

Is it related to rpm or wheel speed? Big difference

Rpm only, when I really push the engine.

That's strange. Does it also do that when you're standing still and revving the engine?

There isn't anything directly connected to the engine back there, so I'm not really sure what could be the culprit, unless something is resonating
