Hi - not sure if this was covered in an earlier thread, but a failure at 55,000km is deemed an unacceptable product performance and reliability - you will be surprised that you, the Consumer has right under consumer guarantees and warranty to have Ford replace these at no charge to you!
Be prepared through to do the leg work as the Ford Service Manager is trained well to resist all cost wherever possible that is warranty is dealer have a hard time recovering this via Ford and anything they can charge out is easy money, but you will find with some patience and constant calls to their Customer hotline you will have these replaced at no cost to you!
Ford are still doing repairs to cars for warranty works free of charge for cars up to 7 years, and no one will ever publish this officially!
Make sure all service records are in order and quote them the ACL (read it cover to cover). Hope it helps!
