As per title. I have a vibration/knock from centre tunel midd way on hard accelaration E46 320d 2001 the prop is in 3 parts. I have replaced 2x centre bearings [febi] guibo as well [this was a cheap one from GSF as thats the only one they had] Still the same maybe a little less violent. My subframe bushes were shot as well so put a good second hand subframe in with good bushes, this had made it a little better but vibration and knock is still there. I had a look at the prop UJ's and one has a very slight play but don't think it's enough to make it vibrate so much. I have tried diffrent tyres still no luck. Subframe body mounts are good. The question is anybody has any idea what else it might be before I throw a prop on it? [got one sitting in a garage] Is there a special way the prop should be lined up/fitted? Thanks in advance for any suggestions.
