Just back from a reasonably long journey. On the way down I could swear I was hearing a background droning noise not heard before. Thought I was maybe over thinking it but appeared more prevalent on way back. Due a service so will ask them about it, but I've read on here a wheel bearing issue is not uncommon. Was thinking it could be exhaust related while in the car but can't really replicate it by reving the engine at a standstill. Any thoughts? Thank you.
