Low howling noise in driver-side front end?

[Fox Hunt]

I last night I did a 4x4 boost launch just to see my 0-60 and after I had this howling noise in my driver-side front end. I had this same noise before but it went away while driving and last night it didnt. When I speed up and then let off the noise is still loud like its not associated with the engine. Its not real loud but I guess a howling noise would best describe it. I dont know if its a wheel bearing or what. I 'v never had one go out so I dont know if that what it is or not. Anyone have any other ideas?

Sounds like a wheel bearing to me. Easiest way to tell would be to jack up that side and grab the wheel at top and bottom and check for play. Also spin the wheel and see if the bearing is making a growling sound.

Grabbing the top and bottom could give you a false reading for ball joints. You better off putting you hands at 3 o'clock and 9 o'clock position. After you jack up the wheel, have a helper push and pull on the tire, alternating the push/pull, while you look underneath at the rotor and a non movable part like the steering knuckle. While the helper is pushing and pulling, look for movement of the rotor compared to the knuckle. There should be no movement/clicking of the rotor.

For ball joints, have the helper put his hand at 12 o'clock and 6 o'clock position and push-pull alternating the movement. You can look at the upper and lower ball joint for movement. Again there should be no movement of the ball joint socket.

Okay thank you guys. I'll check it out. The not hearing it all the time is whats really throwing me off. I would if I had a problem like that it would be there all the time, but I guess we'll see.
