    Squeaking when turning after just starting up.

    Alrighty, here's the lay down. I just replaced the front wheel bearings, but still nothing different about the squeaking. I suppose I should have been smarter about it, since it has just come to my attention that the noise is not supposed to happen when going over speed bumps too. Mechanic...
