View Full Version : Driveline Vibration

My Touring has a slight but noticable vibration that seems to be coming from the drivetrain and is road speed related rather than engine speed. I notice it most if I pull away from a stop briskly until I get to about 20mph. If I take it gently it is barely noticable.
I'm thinking it might be the Guibo in the driveshaft (I assume I have one - I haven't yet looked - just got the car) or am I witnessing the first signs of potential tranny problems?:yikes: Transmission seems fine with crisp shifts and no slippage.

I'd start with the guibo. It might be a good idea to do the center bearing while you are down there.
There is a small chance that your car threw a driveshaft balance weight. They can rust and fall off (dont hear about it much on e34s).

it is almost guaranteed to be the CSB. on a 93 it is guaranteed that the rubber will be sagged inside it.

My 540i has the same problem. I just had my car to the local mechanic and his view is that once you start getting the vibration that one problem area could lead to another and once you replaced the guibo and the center bearing and checked the shaft for balance that you might as well replace the shaft. I decided to go that way and found a driveline rebuilder who rebuilds the shafts and puts a replaceable CV/u-joint on the tail end. I will get mine next Tuesday and will pass on how that worked for getting rid of the vibration.
