A bit of an update and hopefully a bit of help if anyone has any ideas of the best route. I had the car up for a mechanic to have a quick look before it is booked in properly next week. It is coming from the power steering box area there are clicks now rather than one click on turning it feels like the likely candidate is the power steering box or more specifically the arm that is off here and attached to the rack...Chrysler Crossfire 3.2 Petrol 2004 POWER STEERING PUMP BOX 2024610701 1244611105 .

Is that a common issue and should I replace pump or is the arm that seems to attach as a separate item as my gut tells me it's the arm moving on the teeth making the clicking. The car only has 50000 miles so not overly high miles.

I might be way off but wanted to try and get parts sorted prior to the visit.
