Do I have a court/sue worthy case? Auto.?

I got my car back from the auto shop on monday. It had work done to the front axels. So today I'm driving down the interstate in rush-hour traffic (luckily), going about 15-20 miles per hour, and all of the sudden my steering wheel becomes loose, and the car screeches, skids and jerks sideways onto the shoulder of the highway. I was not injured in any way. Road-side istance came to help me soon after. The man was instantly able to identify the problem, and it turns out that when the auto shop finished work on the axel, they did not tighten a very crucial bolt, and/or put in the safety pin to keep it secure. One of the two was not done correctly, because had it been, this would not have happened to me. The tire was essentially detached from the axel, making my steering wheel useless. You can picture this as my two front tires pointing at each other by the time i came to a screeching stop, like this -- / \. I can promise you all that had I been driving at normal interstate speeds when this happened, I would not be typing this right now. What kind of legal issues are at hand here? Do I have the right to sue the company, or simply the right to demand free repair?
