There is your first problem. Sears and I suppose big 10 are mostly tire stores and do what we mechanics call "Gravy hits", meaning they take all the highpaying and easy stuff-tires, batteries, chargins systems, starting, tune ups and front end work. They take none of the hard stuff or stuff that is harder to diagnose. Yuo are better off to find an independent mechanic shop or a dealer, although dealers can p=be pricey. I'm sending along a tsb that may have soemthing to do with your vehicle. An dyou can try this in your driveway, move the front tires to the rear and rear to the front. Sometimes this cures it.
