Thanks for the feedback guys

I'm pretty sure its not tyres, i struggle to see how it could start all of a sudden and no handbrake turns or extreme driving

I'm not sure if its connected but i heard/felt a "ping" sound from the front right of my car turning onto my drive a few weeks back. Initially i thought i had scraped the underside going onto my drive, but as i straightened the steering it "pinged" again (hasn't done it since).
I'm currently waiting for 4 new monza's to arrive under warranty. I reported this sound i heard 2 days before the warranty ran out so they will be looking into this noise at the same time. Hopefully i can convince them this noise has now resulted in this "moaning" noise. Which to be honest, i think it has been there ever since??
How easy is it to diagnose bearing problems?

Sounds like I might get fobbed off

I dont mind paying to be honest- as long as its fixed, i will be shipping the car on if this sound is going to be joining me on a daily basis
