2004 Cadillac CTS Axle Shaft

The procedure is to remove the large seal retaining clamp from the CV Joint, remove the CV joint assembly from the half shaft bar, remove the half shaft outboard seal from the half shaft bar, remove the first chrome alloy ball, remove the inner race from the cage, and then clean the half shaft bar.

The procedure is to raise and support the vehicle, clean any dirt from around the Differential drain plug, position a drain pan under the drain plug, and then remove the drain plug from the differential and drain the fluid.

You should replace the Driveshaft completely.
