If I go over any large bump in the road (ie a speed bump) I hear a creaking sound come from the front driver's side wheel area. What things are in that area that I could possibly lubricate so I don't hear that sound? I'm sure it's not a CV because all the boots in the area are just fine.

I know that the creaking sound from the rear of my car can be fixed with a little grease on the swaybar bushings.
