Owners of 05/06 GTs need to check the power steering return hose going into the bottom of the PS reservoir. It is the larger of the 2 hoses. If it feels greasy or just plain nasty, it is deteriorating. Rich Brooks of the GT Garage and I have changed some, but at this point Ford no longer services this hose. We estimate that most 05/06 GTs will need a replacement hose. While we have not seen any complete failures, it is reasonable to assume that may be an issue at some point. Now for the good news. Rich and I have secured replacement hoses. I will have 80 - 100 hoses at the upcoming Rally 13 in Scottsdale, and more will be available through Myself or Rich.
