Ford Focus ST MK3 clicking on steering?

Hi, I have recently noticed a clicking sound when turning the steering wheel on my ST. It only really clicks when steering wheel is centred. I have jacked the front end up and once done the noise goes, suggesting its links to a load bearing problem. There's no play in steering wheel and suspension seems fine. A mechanic has suggested steering rack problem but I was just wondering if anyone out there with this model or any other car has come across anything similar? Before I take this into Ford and fork out a fortune. Any ideas would be grateful. Cheers

Don't take it to Ford - they will take you to the cleaners.

Take it to a few mechanics and get quotes for fixing it.
