The car wants to take a different track (change direction) after it hits a bump. You'll feel the steering wheel jerk a little too. I call the problem "runflats".

Here's a pretty good explanation:

Big problem for race cars.

Then there's tow out in turns, Ackerman, Steering Axis Inclination and scrub radius. Steering and suspension geometry can get pretty complex.

If I knew all this stuff I could have Chad Knaus' job.
