After driving my 2011 JK Sahara for almost 2 hours today, i arrived in my driveway at home, and while trying to pull into the garage, the steering wheel locked. I cannot turn it in either direction. The Jeep turns on and off fine with the key. I can turn the key to start the ignition, however i cannot turn the wheel. I have tried some of the YouTube recommended videos of pulling the wheel to one side or the other while also turning the key, but cannot unlock it. Checked my power steering fluid reservoir, and it is about half full. Can anyone make a suggestion before i have it towed to the repair shop?
