Hello to all I am new to the forum I have a question I have a 2020 RAM 1500 BigHorn 5.7 with 13,600 miles I have been having issues with the rear differential thump when you stop and slight thump when you take off I have taken it to my local dealer with no luck I just took it to another dealer who says it might be the drive shift has anyone out there had the same or similar issue and had it fixed.
