    Ahhh... that would finally explain that weird "humming/whining" noise I was getting from the rear end. I only ever noticed it on one day when I was driving about an hour away for a wedding and back. Bummed me out pretty hard since it was quite loud and I figured the dealership would never figure out what was causing it (without breaking more stuff along the way).

    Is this a lengthy/major repair?

    Interesting. My driveshaft has been put in my car four times now, all with different whines emanating....

    OEM placement - whine at 40-50 mph
    Second placement - NO whine at any speed
    Third placement - NO whine at any speed
    Fourth placement and currently - whine at 60-70 mph

    Defective CF 4" DIA shaft - much louder whine 60-70 mph

    Oh hell, might as well let everyone try again!

    Will the prop shaft be replaced even if no issue is reported?

    How do you know when your car was built? My car was delivered in late November I have had this whine from day one.

    Driver's side door tag...a little cryptic, but you can decipher...your Dealer can run the VIN and tell you also

    My cat was born on 11/15/15 and has a definite whine above 60 MPH. Hopefully I can find a dealer here in Germany that can service it.

    Look for MDH on door tag.
    MDH = month day hour

    So it appears this TSB doesn't apply to Challenger Cats built after first quarter 2016 (?)

    no, noise would have to be verified.
    BTW--a bad shaft usually makes a rotational vibration not a whine..
