Installed a front right Timken bearing. Now it's like screaching but not continuously just randomly on and off and it's worst at high speeds. And when I turn there's like a grinding noise. Before it was a humming so I knew the bearing was bad now that I replaced it I figured it'd be okay now this sound. Any ideas? Solutions?

 

It's sounds to me that the installation was not done correctly. Go back and retrace your steps

 

did you end up with a bunch of extra parts lying around?

j/k...

sounds like the install didn't go so smooth. Also, did you check the hub as well? I rode on my bad wheel bearing a bit longer than I should have an ended up having to replace the hub and bearing.
