This high quality heavy duty 1/2 inch drive Urrea 10 mm Hex Socket is the tool you will need to remove the center bolt holding your steering wheel to the steering column. See Kents video on steering wheel removal on the tech help page. Without the proper socket and procedure you can damage the bolt and you may end up having to drill it out!!!
If you are not sure you need this socket for your model just pull off the rubber horn pad and look down inside. The bolt should look like the one pictured below:
Notice how this one is starting to round out. I bet it was not removed properly and YOU DO NOT WANT that hex socket to spin a round hole in the top of this bolt!!! Don't ask me how I know this.. :-)
