turbo wheel

So i decided to take my intake off to check my turbo wheel and check for play, when i looked at the wheel there is some motor oil not much sitting next to the wheel, the turbo wheel has up and down play didn't check in and out and also it spins freely then hits a spot where its hard to turn...

I just got done installing a new turbo wheel from Riff Raff diesel. When i finished i took the truck for a ride in my 120hp setting and when the turbo spools at high boost it makes a wining sound. Its not the turbo whistle. Could this be a boost leak? Or what? Any help would be much appreciated...
