all sound advice there nrgserv I never trust garages either and I work in one. I always show the dead parts to the customers to show what I am going to replace then show them once they are removed aswell but alot of the time the customers still have no idea what I'm showing them. Ive even had people ask for their brakes to be replaced then told me I don't need the locking wheel nut key cos I won't be taking the wheel off to do it :frusty::frusty::frusty:
