Due to deterioration of internal lubrication, the front lower ball joint may wear prematurely, causing increased steering effort and possibly noise in the front suspension. If the vehicle is continually driven, the ball joint may separate from the knuckle and cause a loss of vehicle control. The recall began February 28, 2007. The Toyota recall number is 70B.
