I used to manage a major tire store many years ago and I remember that Midas had the biggest up-sale numbers in the market. I had my Jeep Cherokee in to Midas for a muffler replacement when I noticed a young woman with the same model Jeep as mine. She was being sold a brake job and they were telling her that she should have the front wheel bearing repacked while they had it apart. I pulled her aside and explained to her that her car has sealed bearings on the front and they couldn't repack them if they wanted to. Not a good track record.
