elka Posted January 19, 2019 Report Share Posted January 19, 2019 I have a 2013 (9/13 manufacture date) MKX with S-154-A (DT4W-4000AB) differential assembly/axle carrier with axle code 3F (which I think means it has a 3.39:1 gear ratio) that has failed pinion bearing/gear. Will a 2015 S-162-A (F2GW-4000AA) fit if I replace the 6 bolt input flange with the older 4 bolt input flange from the S-154-A and replace the later aluminum brackets with the earlier stamped steel. Oh, and what numbers must match on the diff label/bar code to avoide needing a reflash of the 4X4 module? Much thanks. I have been researching a lot, but am still a little vague on the significance of the numbers James Attached pics of both the existing diff tag and the potential donor tag for comparison. Thanks Quote Link to comment Share on other sites More sharing options...
