Driveshaft vibration - but is it?
My dear Alfa GT Blackline (1.9 Deisel) started getting vibration in 5th and 6th when putting on the power (particularly lower down the rev range) - went as soon as checked by coasting at same speed - seemed to rule out balancing etc.
So, thoughts went to drive shaft and looking here of course, loads of instances where this is debated, and almost convinced that was it - likely the nearside which seems most prone.
Then today, noticed similar vibration during medium braking, both with engine assisting and when in neutral.
Sorry to bore everyone with yet another debate on vibration/driveshaft but this seems just slightly different to what most have reported.
