Strange vibration/noise
Hi all, just looking for some help with a strange noise and vibration I am getting on my 2009 auto D3. When travelling in 5th gear with tc locked at around 1200-1600rpm there is a strange noise as I release the throttle, the only way I can describe it is like when the exhaust touches the chassis and you get resonance sound. If I just feather the throttle I can sometimes make the noise appear but its always worst as the throttle is released and it is only there for a split second. I can just about hear/feel it in 6th gear but 5th is where it's worse, if I press the throttle harder to increase the torque it disappears and only comes back when I throttle off. I replaced rear prop as centre bearing was in a bad way but that didn't cure it, have checked engine/trans mounts, exhaust mounts etc. Just wondering about front prop ? Other than this noise it drives perfect, very smooth with a lovely gear change, no tc vibrations or rev fluctuating, all drive line fluids replaced. I m sure it's some kind of drive line torque vibration, have any you guys experienced anything similar ?
Thanks for reading my post.

Propshaft centre bearing, the rubber mounting fails. Common issue.

Mine had vibration/ resonance when lifting off the accelerator no noise at all when accelerator down. Unfortunately it was the front diff bearings, excellent company near Sparkbrook in Birmingham took off, referbished it for me and re fitted.
