  1. NOTE: When performing the next step, position a drain pan under the carrier assembly to catch the lubricant when the carrier is separated from the arm.

    Support the carrier with a suitable jack and remove the bolts retaining the carrier to the support arm.

  1. Separate the carrier from the support arm. Remove the carrier from the vehicle.

  1. Place the carrier in Bench Mounted Holding Fixture T57L-500-B and Differential Housing Spreader Adapters T80T-4000-B.

Installation

  1. Make sure the bearing bore is free from nicks and burrs. Install a new caged needle bearing on Needle Bearing Replacer T83T-1244-A with the manufacturer name and part number facing outward toward the tool. Drive the needle bearing until it is seated in the bore using Driver Handle T80T-4000-W.





  1. Coat the seal with High Temperature 4x4 Front Axle and Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A. Drive the seal into the carrier using Needle Bearing Replacer T83T-1244-A.





  1. Install the slip-yoke and shaft assembly into the carrier so the groove in the shaft is visible in the differential case.

  1. NOTE: Do not tap on the center of the snap ring. This may damage the snap ring.

    Install the snap ring in the groove in the shaft. Force the snap ring into position with a screwdriver as shown. Remove the carrier from the holding fixture.





  1. Clean all traces of gasket RTV sealant from the surfaces of the carrier and support arm and make sure the surfaces are free from dirt and oil.

  1. NOTE: The bead should be continuous and should not pass through or outside the holes.

    NOTE: The carrier must be installed on the support arm within five minutes after applying the RTV sealant.

    Apply a bead of Silicone Rubber D6AZ-19562-AA (clear) or -BA (black) or equivalent meeting Ford specifications ESB-M4G92-A and ESE-M4G195-A, in a bead 3-6mm (1/8-1/4-inch) high and wide.

  1. Position the carrier on a suitable jack. Install carrier in position on the support arm using guide pins to align. Install the attaching bolts and hand-tighten. Tighten the bolts in a clockwise or counterclockwise pattern to 41-54 Nm (30-40 lb-ft).

  1. Install support arm tab bolts to side of carrier. Tighten bolts to 115-135 Nm (85-100 lb-ft).

  1. Install both front wheel spindles and the left and right shaft and joint assemblies as described in the Removal and Installation portion of this section.
