My opinion would be to take the car to another shop and let them look at the car and see what it is they say is wrong. To me 3k is a lot of money to spend on that. I am not in any way saying they are wrong or anything like that but a second opinion is a great thing to have. I would not inform the other shop what anyone has said. that is just me though. You can drive the car the way it is but you will go through tires quicker than normal. Not to mention vibrations and handling issues that will arise.
