Going nuts-- clunkidy clunk

[Naz24]

Ok... This is finally driving me off the walls!!

Under acceleration, between gears, I get a good ole clunk coming from front suspension ( I believe it's from there). I feel it on the floor, in the steering wheel, and my passengers feel it too... Now this only happens when the car is warmed up. The ball joints are less than a month old, and the control arms were done 15k miles ago.

Now follow me here... Perhaps the cv joint? When it warms up, the oil separates causing it to slip? Could it be the entire front axel? I'm at such a loss.

Or could it be in the driveline? This problem is making me want to pull my hair out. I don't feel it if I accelerate hard... Usually happens around 3k rpm?

Help.
