It's hard to expalin, but it just feels like something is "loose" in the area of the right front tire. There are not particular sounds coming from the area, but I can feel a constant "humming" type vibration in the steering wheel, and just that sensation of something not being up to snuff. Had the ball joints replaced less than 1000mls ago. I know this is vague, but any ideas?

 

Take a close look at the trackbar. Have someone else fire up the motor and turn the steering wheel from lock to lock. While you're laying under the front bumper you should see the trackbar ball joint pop and move where it mounts to the frame; if it bad that is.

 

Maybe a wheel bearing starting to go? Possibly that combined with another problem?
