need your help !!!

Hello community,
have a big problem and hope you can help me.
I've always had such a metallic bobbing and beating in the area of the front axle until recently. Then I checked the suspensions of the spring legs and axle. But it could only move with a very large amount of effort (with the Montierlebel). So I assumed that it could not be the camps or suspensions. But since it came from the beginning, and I had to make the shock absorbers again anyway, I changed the cathedral bearings immediately. Since then, the metallic clapping has gone away, just a dull, hard beating from the front. You have to think of it as if you were pumping the tires up to 10 bar (you can hear every change in the road) and as if the shock absorbers are strong and would not be pushed in. This is the case, for example. when driving over new on old road surfaces to feel a hard blow through the whole body. And with such small transitions, there must be nothing to hear about such a car.
Can you help me and tell me what else this could be???
Thank you and I hope to post.

Greetings Manuel

PS. I took a lot of time to install the shock absorbers and dome bearings and kept exactly the right seat and didn't forget anything. Trace and fall were then also re-set (but almost did not need to be changed). Tires are from last year and okay. 195-65-15 by Conti
