When I take a sharp corner I lose ability to steer, the truck makes a sharp pull to the right and then it feels as if the front tires are going in opposite directions. Some times the problem disappears in a few minutes, some times it will feel this way for miles. If you turn the truck off for a few hours, the problem is gone until it decides to rear its ugly head again. I have had the power steering pump, u joint, and axle joints replaced along with new brakes, new tires and several realignments. The truck only has 111,000 easy miles on it, and now I have been told to never try to pull my horse trailer with it, better yet dump it!
