    vibration mystery.. solved?

    Underneath the car today to fix stripped roll bar nut. Ya don't use a gun! Duh.

    I poked around the drive shaft and finally was able to see the carrier bearing while moving the shaft. I'll let the video do the talking....

    That's normal. It is a rubber molded bearing.

    b5 s4's have them as well, and i had one go bad on my second s4. You would know if that was it. You would feel like your driveshaft was hitting the tunnel when you accelerated.

    its also designed to dampen the vibration of the drive shaft, in addition to supporting it.

    Yea. The vibration is somewhat varied in severity and worse on acceleration. I feel it most in the seat. This much movement can't be right and I've already replaced all control arms, bushings and ball joints and drive shafts and wheels..... what else is there?

    There should be movement at the Carrier Bearing but at least from the video that does definitely seem excessive. The are a pain in the ass to change just for the work involved but they are cheap. Porsche Cayenne's eat the Carrier Bearings every 50~60K miles.

    Id say so...especially if most of the vibrations you are feeling are at your seat. Next time you are out, bring someone along and have them put their hand on the tunnel in between the rear passenger footwells. Then accelerate. Should pinpoint it fairly well.

    Is changing the carrier bearing/bushing easy for a prop shaft company to do, or is there something inherently more difficult (surprise) with our setup?

    I have found a new complete prop shaft for 400 with only 7000 miles on it.. I may go that route.

    IIRC, you have to remove the u-joint, then use a press to remove the bearing off the shaft. Plug and play for 400? Pretty cheap as our cars go...
