Steer wheel and whole jeep shook when turning
I have a JK. When I accelerate and turn at the same time, all of a sudden my whole car shook violently. It just feels the whole car was out of control. I was able to brake but wasn't able to straighten the wheels until it was almost come to 20km. Maybe I hit a bump but not a big one for sure. Once I straighten the wheels the car stabilized, I can pick up speed again.
It happens to me a few times already when I was turning onto a freeway and almost got into accidents.
I just replaced a new engine block about a month ago, I don't think that has anything to do with this problem but just in case.
Any idea where to start?
