Thanks
I am going to try cleaning it up first
The meat head that owned it before said it always makes that noise at first start up
Well I felt that MB doesn't build stuff that squeals by design
so I pulled it apart
As DOC said It only works for start up so I thing it will rotate atleast
I cleaned everything and replaced the front frozen bearing (not the idler one)
what a mess to do
if only people would react when they hear something it would be alot easier
