Whenever I turn the steering wheel to either the left or right wheel locks, and I am just letting the car roll and idle (in drive) the steering wheel tends to jerk back the other direction just a little, and the back to the wheel lock and over and over again.. It's like the tires are slipping on rocks or something. Could this be bad tie rod ends or something with the power steering? And sorry if I didn't explain well, if you need more info I'll try to explain it better. I've noticed it does this on any kind of road surface I am on.
