[1stgenbird]

I have been trying to resolve a ride problem with my '67 with no success.

When driving over 30mph, anytime I go over a dip or bump in the road, the car seems like it bottoms out with a loud bang.


I keep the bird original with mono-leaf springs, both radius rods, Koni Classic adjustable shocks.


All the suspension bushings have been replaced in the past couple of years. I went with the Konis two years ago. Last year I replaced the rear springs with new mono-leafs from Eaton, thinking that the ones I had may have been original and lost some of their effectiveness. I can't say there was much, if any, improvement.


I can't believe these Birds acted like this when new. Anyone else have this issue?
