    Yes the rear diff is shifting a bit (not good) and this is caused by the rear lower control arms.
    There was a recall for them by dealership, free replacement if they have not been replaced yet.
    Type you VIN number in here to see the current status: https://www.mopar.com/en-ca/my-vehicle/recalls/search.html

    Be interested to know if you could look at the new arms, to see if they have a slot or a cut away, on the axle side rubber bushings of the new rear LCA's.
    If they do have the slot/cut a way...do what I did, fill the slot in with a marine polyurethane, or windshield urethane and the problem wont come back.
    Let cure for 3 days then install.
    It worked for me, on my 04, but I used the OEM LCA, with Spicer bushings and had them pressed in with a 4x4 shop that had a 25 ton press.
    They had to torch/ burn off the old ones, before pressing old ones out.

    I would also recommend that the upper rear boomerang & ball joint be inspected for movement and wear as well.
