To remove the left side of a vehicle, first loosen the wheel lug nuts, raise the vehicle, place it securely on jackstands, and remove the left front wheel. Then, remove the differential carrier splash shield from under the front axle and the left driveaxle. Drain the lubricant from the front differential and pull the left axle shaft out with a slide hammer and adapter. Remove the deflector and seal from the differential and remove the bearing using a slide hammer and bearing remover attachment. To install the left side, first install the bearing with the square shoulder facing in, using a bearing driver or a socket with an outside diameter slightly smaller than that of the bearing. Then, install a new seal and deflector, lubricating the lips of the seal with multi-purpose grease. Carefully drive in the axle shaft with a soft-face hammer and fill the differential with the proper lubricant. Install the driveaxle and differential carrier splash shield, then install the wheel and lug nuts. Lower the vehicle, tighten the lug nuts to the proper torque specifications, and check for proper operation.
