NNV Posted May 14, 2021 Report Share Posted May 14, 2021 (edited) Hello. Help me solve the following problem: is it possible to install a rear axle gearbox from the 2011 model on a 2014 car? The original 2014 part number is, and the part number from the 2011 car is. Are they interchangeable or is such a replacement not possible? Thank you very much for your answers Edited June 11 by 1004ron Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 14, 2021 Report Share Posted May 14, 2021 Should be. Just have to update the ATC strategy code (from label on the unit) so the RDU can be controlled properly by the PCM. There are officially 3 revisions used in gen 1.5: Production Date: 06/2009-08/2010 08/2010-07/2012 07/2012-04/2014 I have not seen any mention of specific changes in the factory manuals, but there may be slight differences in mounting. Sometimes they like to eliminate fixtures they deem unnecessary. 1 Quote Link to comment Share on other sites More sharing options...
Bobintar Posted October 18, 2022 Report Share Posted October 18, 2022 Did this replacement work for you? My 2014 RDU is cooked and its about $2200 Cad plus shipping for a new one. I can find a used the S-154-A/D much cheaper than the new one. Also, has anyone tried to rebuild one of these RDUs? Quote Link to comment Share on other sites More sharing options...
powersound2007 Posted January 4, 2023 Report Share Posted January 4, 2023 I'm also trying to solve the problem with the AWD machine of 2013! I studied this topic as much as possible and concluded that the rear gearbox from 2011 is not suitable, since its gear ratio is 2.91 and on my gearbox it is 2.92!!!! It is not possible to find a new or used S 154 A or S 154 D!!! CAN someone give me some advice on what to do? Can someone share a link where you can order the gears of the main pair of the rear gearbox separately? Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted February 13, 2023 Report Share Posted February 13, 2023 Would something like this work? https://www.rigidaxle.com/products/1981-2014-ford-8-8-10-bolt-ring-and-pinion-gear-set-w-master-bearing-kit Quote Link to comment Share on other sites More sharing options...
jspec Posted June 11 Report Share Posted June 11 Did anyone actually replace the rear end with something other then a S154A. Would the s164A work? Seems like they are just revisions of the rear end. Quote Link to comment Share on other sites More sharing options...
