Ford 8L8Z-4K138-A Shaft Assembly

To install the front driveaxle, follow these steps. Pry the old spring clip from the inner end of the driveaxle (left side) or outer end of the intermediate shaft (right side) and install a new one. Lubricate the differential or intermediate shaft seal with multipurpose grease and raise the driveaxle into position while supporting the CV joints. Push the splined end of the inner CV joint into the differential side gear (left side) or onto the intermediate shaft (right side) and make sure the spring clip locks in its groove. Apply a light coat of multipurpose grease to the outer CV joint splines, pull out on the steering knuckle assembly, and install the stub axle into the hub. Insert the ball joint stud into the steering knuckle and tighten the pinch bolt. Install a new driveaxle/hub nut and tighten it before lowering the vehicle to prevent wheel bearing damage. Grasp the inner CV joint housing (not the driveaxle) and pull out to ensure the driveaxle has seated securely in the transaxle or on the intermediate shaft.

To install the intermediate shaft, follow these steps. Lubricate the lips of the transaxle seal with multipurpose grease. Carefully guide the intermediate shaft into the transaxle side gear and then install the mounting nuts for the bearing support and tighten them. The remainder of the installation is the reverse of removal.
