hi all i have a 2000 s10 4x4 that has developed a noise, like a rubbing or something. the noise grows with speed when going straight or turning to the left...when i turn to the right it goes away. 4x4 is working fine and noise is same in 2 or 4 wheel drive. one friend says its a bearing or something and another said maybe a cv joint maybe. i think neither of them know what they are talking about. any help would be appreciated.
