I have a problem with my 56 Patrician.Upon hard acceleration, I get a severe vibration that smooths out after a few seconds. If you kick it down at high speed, it jumps and there is no vibration.Any thouhts



I have a similar sounding problem with my 51-300. What I found is happening is, under high acceleration, (That's a laugh isn't it?) the car squats and the rear axel twists which causes the rear universal to hit the bottom of the body. There are marks in the tunnel where the universal contacts the body. I don't know but I suspect that the problem is caused by weak leaf springs. Never had any of my 50 or 60 cars do this before. This is a new one. Now that I think about it none of the cars I've had were 57 years old when I had them. Not even the 31 ford which I bought in 1968. Should have never sold that car.
