if I ever take my car to the shop, I will be right in front of them and watch them.
like I take my car to the tire shop, they jack my car up using the rear differential, I told him " are you crazy ? put that god dam jack on the side, not on my differential !! " he told me it fine, lucky I have a ford manual with me, and I turn the page where it say do not use rear diffrent to put the jack, then he put the jack on the side. I make a complaint to the manerger, they cant take a short cut and jack the rear up using your rear differential as a support, ****ing dumb.
