Thanks for that Pete I will check the engine mounts. My next plan is to put it on blocks and see if I can get it to make the noise off the road so I can better pinpoint it. I was given this car by a friend who died of cancer so that I could sell it to assist my daughter who now has stage 4 breast cancer with her treatment, so it will be great to sort this issue out.

Hi there. I am a new guy to this site but owned hearalds for many years in my youth. It is a long story I am trying to get a 1967 1200 herald in a state where someone might want to but it. It has been shed stored for about 10 years that meant i had to replace most of the slave cylinders but at last I have got everything sorted and it is running beautifully except....there is a distressing loud vibration noise that sounds like the prop shaft (or perhaps the exhaust) that only occurs when there is no load on the engine. Under acceleration, nice and quiet. Slowing down, nice and quiet. That sweet spot when you are at the speed you want to cruise at with no loading on any of the shafts...horrible loud noise that sounds like something is in the process of falling apart. I was just wondering if anyone had experienced this before and if you had any ideas as to where to start.
