This past winter I had my truck at a local tire shop for an oil change because it was -11 outside. They told me 2 seals on the diff. were bad and wanted $650 to fix it. At the time I wasn't in a good position to have it done, but they said I could go a while with no issues (seemed a little odd but I went with it for the time). Anyway, fast forward to a month ago when my transmission went. I was in a much better spot so decided to have it taken care of. I told the guy at the transmission/differential place about it to get a quote. He went to take a look, and lo and behold, no issues! Flat out lied. Needless to say they aren't gonna see me again. And a few days ago a buddy had his old corsica in for a fuel injector problem, and of course his starter went out when he was there (right......)anyways he tried to get the old starter back, even offered to pay for the core (as he told me) and they wouldn't return it. Charged him $400 to replace that. Ok, im done now, just made me mad....
