they wont have touched the power steering fluid on your car unless you agreed to it
you aint got 80psi in the tyres have ya ( just asking

)
37k service is just a engine service and all other work that needs doing like fluid ect they would have spoke to you about after and then you would remember cause at 90 quid plus vat for a service and then the price of the parts you would notice on the bill
cheack the links and see if there worn i supose but th ford would have noticed that too ( anything for cash

)
