As you are in the hands of people who claim to be experts (and have followed their recommendations) this experience and its follow-up to satisfactory completion will not cost you one penny? But then it could be argued that you should not be given brand-new units - an improvement - but should be placed in the position you were in before the fault developed, with all of its fair wear and tear. Were brand new units fitted or 'reconditioned' ones I wonder? Did they check the suspension and engine mountings as well when it was up in the air?
