Toothed Ring

NOTE: To service the speed sensor ring, the differential case must be removed from the axle housing.






REMOVAL
1. Remove the bolts retaining the ring gear to the differential case. Remove the ring gear by striking at alternate holes around the gear.

CAUTION: Extreme care should be taken not to scratch, dent, chip or otherwise cause damage to anti-lock brake sensor ring teeth while handling or during assembly.

NOTE:
^ Before removing ring gear inspect it and determine if ring runout check is necessary.
^ Do not remove anti-lock speed sensor ring unless replacement is required. It does not have to be removed for ring gear replacement.






2. If replacement is required remove the anti-lock brake sensor ring by tapping with a soft-faced hammer. Discard the anti-lock speed sensor ring.

CAUTION: The anti-lock speed sensor ring must be discarded upon removal. If removed, a new anti-lock brake sensor ring must be installed.






INSTALLATION
1. Position the ring gear and anti-lock speed sensor ring on the differential case. The tab on the anti-lock speed sensor ring must be aligned with the slot in the differential case as shown. Start two ring gear retaining bolts through the differential case into the ring gear to make sure case-to-ring gear bolt hole alignment is achieved.

CAUTION:
^ Extreme care should be taken not to scratch, dent, chip or otherwise cause damage to anti-lock speed sensor ring teeth while handling or during assembly.
^ The tab on the anti-lock speed sensor ring must be aligned with the slot in the differential case.

2. Press the ring gear and anti-lock speed sensor ring on the differential case using the ring gear as a pilot.






3. Coat the threads of the ring gear retaining bolts with Stud and Bearing Mount EOAZ-19554-BA or equivalent meeting Ford specification WSK-M2G349-A1. Install the bolts and alternately and evenly tighten to 95-115 Nm (70-85 ft. lbs.).
