A few weeks ago, coming out of Wal-Mart, my car's steering locked up on me. The wheel wouldn't turn and the only way to get it to unstick was to fight it until it would. Well anyway long-story-short, I drove down the road fine until I hit my driveway when it locked up on me again and took me for a ride almost into my house. I stopped it about a foot short. There it sat until a garage came and got it to look at it. They filled it with tranny fluid and it locked up on the first guy and not on the second one. They didn't know what it was. So I took it to the next garage and told them to check the rack and pinion. It was, though they didn't have the right tools to do the job. I called around town until I found a garage that could do it and dropped it off today. It'll take about 2 days to fix and cost about $800 to $900 estimated. So if your car locks up and your not sure what it is check the rack and pinion. I've found that our cars have a history with this problem and found that here:
