Turbo Issues? Faint Siren Sound

Hey guys,

Starting to get a faint siren sound, think this is turbo related. The noise is there between 1000 - 2000rpm. More so when you lift off.

There seem to be no lose in boost or power. Any suggestion?

I'm going to strip down the front pipework over the weekend and check to see if there is any play in the spindle.

Any other suggestions would be great.
