I know this post is late to the game. I posted this information yesterday however I cannot seem to locate the post.
I had a conversation with Eaton on the phone. Person I spoke with was adamant that the electronically activated locker being used in the 2019 -2020 Ram is NOT an Eaton product.
He also stated that the clutch type LSD used by Ram is in fact an Eaton product. He also said that he saw no reason that the clutch type LSD could not be rebuilt if the parts needed were made available by FCM.
I know this goes against what we have thought. I pressed him pretty hard on the subject, pointing out the wording that FCM uses when describing the E-Locker. He seemed to be knowledgeable about the changes that have taken place through the years with the rear axle used in the Ram. This was not some desk jockey whose job is to answer the phone and supply canned responses to questions.
