Dorman - OE Solutions Drive Axle Shaft P/N:630-338A
Keep torque moving from the differential to the rear wheel with the Dorman OE Solutions Drive Axle Shaft 630-113A, a rear axle shaft that installs on either the left or right side. It fits many vehicles, among them the 1977-1985 Chevrolet Impala, 1977-1990 Chevrolet Caprice and 1985-1986 Buick Century. See the "Vehicles it fits" section for the full list of applications.
A factory axle shaft can fail outright or be damaged by rust or a collision. This Dorman replacement is engineered to help transfer torque and rotational power from the differential or transmission to the wheel, as the original shaft did.
Signs a rear axle shaft may need replacing include clunking or vibration from the rear of the car, a wheel that wobbles, or a shaft visibly damaged by rust or impact. If a worn or damaged axle shaft is the cause, this part replaces it. Consult the vehicle service information for the correct installation steps and fasteners.
