If the bolt fracture, the rear suspension linkage could detach from the knuckle and the rear wheel would be able to turn inboard or outboard. Sudden changes in vehicle handling could occur, particularly at higher speeds, and the driver may not be able to control the vehicle and a crash could occur without warning.
Certain passenger vehicles equipped with rear suspension knuckle bolts that are not to specification and could fracture under high loads that can occur in some driving conditions.
Dealers will replace both rear suspension knuckle bolts free of charge. The recall began on February 9, 2005. Owners may contact Chevrolet at 1-800-630-2438 or Pontiac at 1-800-620-7668.
