Unfortunately what happens when they put your car on the lift to do the alternator bracket is it the decompresses the struts all the way and the small cracks which of been developing over the years get pulled open up and actually get pulled apart. So the cracks which were previously compressed are now fully open and it just tears the bags so you'll probably find upon inspection at that bag is completely torn .
