squeeky suspension?

I have a vauxhall corsa design 2005 model. It has an annoying squeek to the front suspension. Its had numerous parts replaced within the last 12 months, shockers, springs,drop links,bushes and steering rack and still this squeek persists. My local garage must think im mad keep turning up with the same problem as they cant find the fault. Its more noticeable when first moving off and when the car is rolling to a stop. Any ideas.

Thanks
