Turbo howling noise

[tbocruiser]

2.4 turbo

So heres how it started.

My cruiser started making loud wind noises,and the turbo stopped working.

After a few days it started back working as i could tell from the speed.

Then it started making the wind noises again and stopped working once more.

After a day or so it was making alot of grinding noises,so i removed the turbo and found out the shaft was broke and had chewed up the fan propeller,

i bought a used turbo (same kind that was originally on it) after putting it back together,i test drive it and its making the LOUD wind noises and not working abviously cause how slow its driving.

any ideas or solutions?
