After having 4 wheel alignment done a few times, trying different things. After fitting now ball joints, track rod ends, track rods, whiteline anti lift kit, wishbone bushes, drop links. Had top mounts and bearings done not too long ago. Everything is pretty much new and it still wants to pull left! if I hold the steering wheel straight it drives straight but if I let it go the steering wheel drops to the left and steers the car towards the curb. it's not the camber because it happened even if the road cambers to the right. if I sit at lights with the engine running and take my hand of the steering wheel it will drop to the left. I have done some more research and read that it could be a faulty power steering control valve leaking or biasely pumping fluid to the left. Anyone experienced anything like this?
