What causes car to feel like its mildly swaying or swerving when driving on highway along with difference in ride bounciness?

[Edit]

Answer

There are three typical causes to the problem you describe:

1 - The front and/or rear-end are out of alignment on the vehicle. Take it in to a mechanic shop that specializes in 2 and 4 wheel alignments and have it checked. Some shops actually offer the check for free.

2 - The tires are not balanced properly and/or there are mismatched tires on the car. Steal belted tires, for instance, react differently than glass belted tires. Having both types on the car at the same time can cause the car to "wander" at times depending on road conditions.

3 - The shocks or struts need to be replaced.
