No previous sounds, squeaks or anything.
Been out in the car tonight, and it's making a lot of noise underneath.
Squeaking, rattling, and a kind of rubbing noise.
If I drive on a straight, smooth road, it's ok.
Can anyone shed any light please?

Been through any road works ? Stone trapped behind the disc try driving in reverse see if it falls out. 2008 G4 RRSport TDV8 current

A stone did enter my thoughts, and done as you suggested.
It is however, a lot more noise than just a stone.

I've just noticed, it's squeaking when I lift and lower the suspension.

Might be a dry joint, see if you can identify which corner. 2008 G4 RRSport TDV8 current

I'll get under it tomorrow, and see what's going on.

Cheers.

Nothing seems loose, or about to fall off!
I recon it's a dry joint or 2.

Mine was making a lot of squeaking when my lower arms were worn out. Front bush and ball joint were ok but the rear hydro-bushes on both arms were completely cactus. Get a pry-bar on the rear bush and test the movement. MY16.5 RRS SDV6 AB Carpathian Grey/black 154k km

Had it looked at today.
ARB bushes making all the noise. No play in them, so the garage lubricated them, and the noise seems to have gone for now.
Would non OEM bushes cause this?
