Please help. When turning the steering wheel sharply to the right it feels like the front right tire is skidding or something and makes a knocking sound. Normal driving and turning feels fine. I thought maybe from turning really sharp could be problem but I really believe something is wrong. No shakes or anything in steering. Drives straight.

2011 touring model
15,000 miles
Warranty just ended in August 2014

Is there any recalls on this? I can't believe I can have a front end issue??

Please help.
