    Center bearing getting preloaded and unloading? Had an Audi once that did something similar until I changed the center bearing. Check the guibo also. Motor mounts in good shape?

    Don't believe the car has a "guibo". The fact that the noise is so intermittent has me baffled. I usually drive the car alone and the noise does not happen at idle speed but I have to start moving from a stop before I hear it. so it is kind of hard to check it on the fly.
    Thanks for the reply.

    Exhaust touching something or a loose mounting?

    Default Bad Center Bearing, Tranny Mounts, and Drive Shaft

    To close out the thread...

    The noise come more often and louder. Don't know the order of failure but the forward joint of the drive shaft that attaches to tranny output was very stiff, the center bearing was totally shot as well as the tranny mounts.
    Replaced them all a few weeks ago.

    Car runs much smoother
