Wrrr sound...

[healtoeit]

I got a wrrrrrr noise coming from my front end. It happens at moderate speeds and above, not at slow speeds. This started happening when I put in new springs (H&R) and shocks(Bilsteins). At the time I had used 540i struts laying around, so I assembled the front struts outside of the car useing the 540i ones. I am wondering if the wrrr could be bad wheel bearings.
Thanks
P.S. the car handles great (except for the tie rod ends, which need to be replaced)

Me thinks bearings too.

Alright man, I'll get the ones off of my old strut back on.
How hard are they to get off?
