What are the codes involved.There is a TSB that sound like it might apply PIT5569a. I have a similar issue but with no comm. loss that is at the chevy dealer who has been unable to repair for over two months. I do not believe they are trying very hard. I have a 2016 3500 4wd dually that sets rear wheel speed sensor codes every time i tow my travel trailer more then 100 miles. At first it was just the right sensor. But now it is both. The right senor was replaced under warranty but did not fix anything. If it is the updated AAM 11.5 rear end the sensors are not at the wheel ends as is normal but at the side of the diff. housing.
