Removal

1. Remove the differential carrier.
   Refer to: Differential Carrier - Vehicles With: Electronic Limited-Slip Differential (205-02 Rear Drive Axle/Differential - Vehicles With: Ford 9.75 Inch Ring Gear, Removal and Installation).
   

1. Using the general equipment, remove and discard the differential bearing.
   Use Special Service Tool: 205-D072 (D97L-4221-A)  2 Jaw Puller. , 205-D061 (D83T-4205-C2)  Step Plate.

1. NOTE: Do not use power tools to remove the component.

   NOTE: The retainer threads are left handed.

   1. Remove two bolts of ring gear mounting to install the special tool.
      Use Special Service Tool: 307-003 (T57L-500-B)  Holding Fixture, Transmission. , 205-1049  Socket, 9.75 Plenum 4 pin.
   2. Apply heat to the hydraulic actuator area to soften the Loctite before using the special service tool.
      
   3. Using the special tool, remove the hydraulic actuator retainer by turning in the direction shown.
      Use Special Service Tool: 307-003 (T57L-500-B)  Holding Fixture, Transmission.

1. NOTICE: Do not disassemble the hydraulic actuator bearing stack or damage to the bearings can occur.

   Remove the hydraulic actuator assembly from the eLSD carrier.
   

1. NOTE: Do dot mix the hydraulic actuator bearings and washers or damage to the bearings can occur.

   NOTE: The hydraulic actuator can be reused if the differential carrier is being inspected for gear noise issue.

   NOTE: Always properly secure the hydraulic actuator assembly with cable ties to prevent the disassembly of the component.

   Using general equipment, secure the hydraulic actuator assembly.
   Use the General Equipment: Cable Ties

Installation

1. NOTE: Do dot mix the hydraulic actuator bearings and washers. The hydraulic actuator bearings and washers must be reassembled in the same sequence.

   NOTE: If bearing found damaged, make sure a new hydraulic actuator assembly is installed.

   If disassemble.
   Assemble the hydraulic actuator assembly bearings and washers in the sequence shown.
   

1. NOTE: Do dot mix the hydraulic actuator bearings and washers or damage to the bearings can occur.

   NOTE: The hydraulic actuator can be reused if the differential carrier is being inspected for gear noise issue.

   Remove the cable tie before installing the hydraulic actuator.
   Use the General Equipment: Cable Ties

1. NOTE: Verify the eLSD hydraulic actuator orientation is correct.

   NOTE: Verify the eLSD hydraulic actuator bearing stack is correct.

   NOTE: Replace the eLSD hydraulic actuator if necessary.

   
   Install the new hydraulic actuator assembly to the electronic limited-slip differential carrier.
   
   1. The eLSD hydraulic actuator piston side and thick washer towards the eLSD .
      
   2. Alignment pin faces away from eLSD .
      

1. NOTE: Do not use power tools to install the component.

   NOTE: The retainer threads are left handed.

   Using the special tool, install a new hydraulic actuator retainer and torque it by turning in the direction shown.
   Use Special Service Tool: 205-1049  Socket, 9.75 Plenum 4 pin. , 307-003 (T57L-500-B)  Holding Fixture, Transmission.
   Torque: 125 lb.ft (169 Nm)

1. 
   
   1. Remove special tools.
      Remove Special Service Tool: 205-1049  Socket, 9.75 Plenum 4 pin. , 307-003 (T57L-500-B)  Holding Fixture, Transmission.
   2. Install two bolts to the ring gear.
      Torque: 140 lb.ft (190 Nm)

1. NOTE: Make sure that the eLSD hydraulic actuator rotates freely on the eLSD assembly in both directions.

   Verify free rotation of the eLSD hydraulic actuator on eLSD and that bearing washers are not pinched.
   

1. Using the special tool, install the new differential bearings.
   Use Special Service Tool: 205-D044 (D81T-4221-A)  Installer, Differential Carrier Bearing. , 205-153 (T80T-4000-W)  Handle.

1. Install the differential carrier.
