Titan steering rack?

Are all Exige S1 deliverd with Titan steering rack?
I hear a little knocking on bad bumpy roads but don’t have play when i move the wheel.
As the winter is near,i will take out the rack to take a look if it is the track rod end or something else,is the steering rack always possible to refurbish?

It’s a shitter of a job. Titan refurbed mine for about £150. Maybe worth a second opinion.
