Hi there

I have had the propshaft on my 1983 1800 Giulietta removed and replaced for gearbox repairs. Now I notice a vibration. It's not the classic gearlever vibration type of propshaft imbalance, which normally would occur also at idle, but only occurs around 4000 rpm, felt more like a "roughness".

What might have gone wrong? Comments will be appreciated
