Ford Territory cracked diff

When I responded to a recall notice to have the dust covers in my 2007 Ford Territory Ghia replaced at Ford's expense I was advised that the rear diff bushes were cracked and required replacement at an approximate cost of $750. I was advised that as the vehicle was out of warranty the company would not help me, there was also talk about loyalty to Ford, which I took to be a reference to my having the 60,000 km service not done by Ford. I do not believe I am unreasonable in my expectation of assistance from Ford. I expected that Ford would agree to undertake the cost, or the very least offer to pay part of the repair cost.
