Bad Vibes......................

[braveheart]

Chaps, i`ve just bought a 350i S2 which i am very happy with apart from a serious vibration that comes in at high speed i`ve checked wheel balance and all o.k but was wondering if could be prop or driveshafts ?any feed back would be grateful.

Could be anything. Propshaft, driveshaft Ujs, Rear wheel bearings, suspension bushes.
Mine had bad high speed vibes and it turned out to be all of the above!

The front UJ on my prop caused a strange coarseness on my 350, even though it seemed fine when I checked it on the car. It always passed the MOT as well. I changed it when I had the prop off to change the rear UJ (as it made sense to do both while I was at it), and the difference in the car at high speed was very noticeable.
