I have a 2002 Tahoe which we bought new and has been pampered. It only has around 93,000 miles on it. It started to have a slit shimmy when turning the wheel to back up and park a couple of months ago. Then the air conditioning stopped working. We replaced the belt and the air is now fine but Tahoe still shimmies. We replaced the power steering pump because fluid was black and thought that might be the problem. Well, it still shimmies when backing up to park. Can anyone tell me what the problem might be???? Please, Help!!!
