2003 GMC C4500 Recall

Campaign:
02V202000 on 07/31/2002
Component:
Suspension:rear
Manufactured:
07/31/2001 - 05/30/2002
Affected:
952
Defect:
Certain medium duty trucks equipped with 11,000 lb. rear axle have a condition where the rear axle anchor plate may fracture. as the anchor plate fractures, there is an audible "bang." if this indication of a condition requiring the driver's attention went unnoticed or was ignored, and under certain rebound, braking, or cornering maneuvers, the rear axle would be free to move fore and aft and provide unexpected steering inputs to the vehicle.
Consequence:
If this happens while the vehicle is moving, a crash could result.
Correction:
Dealers will install a new rear axle anchor plate and spacer. owner notification began august 16, 2002. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020 or gmc at 1-800-462-8782.
Notes:
Also, customers can contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).
