    Question a4 noise

    i just bought an auto '02 formula (104k mi). i thought the rear end was whining (that's what it sounds like) so i pulled the cover, it has 3.42's and a torsen diff (worm gear). is that stock? anyway, the whine isn't from the diff, it's the tranny. the extention housing bushing has just the slightest amount of slack and the seal is just barely seeping. shifts and drive fine. any ideas?

    update

    turns out it was the rearend (driveshaft was carrying the sound), but i might get the tranny built anyway. has anybody had luck with Probuilt's kits? Thanks for any input.
