Front Clunk Bump On Uneven Pavement (cobblestone)
I was in a historic part of town the other day that has cobblestone streets and noticed a lot of clunking coming from the driver front wheel. I'm hoping this isn't new strut time.
I have noticed quicker sagging lately in the front end resulting in "car too low do not drive" (this used to take 6-8 hours to happen and now it's more like 2) which is easily resolved by pressing the height increase button. I attributed this to a valve block needing rebuilt which I've been meaning to do. I don't know if the two are related. The car drives fine over normal surfaces from what I can tell.
I recently replaced all of the forward control arms. Upper and lower. All new front ball joints are also new.

The lower ball joint was just replaced a couple months ago and I don't believe there is any play in it. However, I have not inspected it since I replaced it so it is possible. I have also repaired the upper bush within the last few months using a 10mm sheet of rubber cut to fit per a write up I found on the forum.
As for the wheel bearing, there is a little play in it but not too terribly much. I do, however, experience some humming when turing into that wheel that sounds like it could be bearing noise. It only happens at low speeds from what I can tell and only when steering in that direction.
