    Default R&R Propeller Shaft Flat Rate Hours

    Just trying to find out what flat rate hours are for Prop shaft R&R. I understand this includes either s 2 or 4 wheel alignment. Work is being done under warranty FWIW.. 2015 Z06 A8

    HI there,

    15.3 per Alldata and that does NOT include the alignment. I will tell you it takes me almost 20 hours to CORRECTLY do this job.

    Paul, are familiar with the drive train vibration? Dealer did replace propeller shaft but vibration still there. Car is an 2015 A8 Z06 and I get a mild but noticeable vibration right at 2000 rpm whether accelerating or just setting with car in neutral or park. The vibrations feels like it is coming through tunnel...

    HI there,

    I have diagnosed MANY DIFFERENT causes for this issue. And, the PICO SCOPE vibration analyzer is the ONLY way to accurately pinpoint a vibration source.

    THAT is the most critical area. After that, INSTALLATION PER CORRECT SERVICE PROCESS with a torque wrench on EVERY fastener is required.

    Excellent reply. Thank you..

    Have you seen any common denominators when it comes to isolating this issue? Assemble, flex plate, TC? The Vet Tech working on my car is well respected. With new Prop shaft and same vibration, it makes me believe the issue might be emulating for a different source.

    HI there,

    Back to the point, use the PICO SCOPE and you will KNOW where the source is based on amplitude of the vibration.
