ANSWER: Chance,

Wow, it's time to check all steering bushings, tie rod ends, ball joints, wheel bearings and have the front end aligned.

This can occur if the pressure is too low in the tires.

Broken or bad suspension parts can cause this also.

QUESTION: It sounds like I should take it to s ahop some where and not try to fix it at home


Answer
Chance,

If you are somewhat mechanically inclined, I would suggest that you purchase a repair manual ($20 or so) from your local auto parts store.  These manuals have full trouble shooting sections, photos and diagrams.  They are invaluable if you plan on doing any trouble shooting, or work on your own vehicle.
This way you can try to check out the problem.  Some of these are fairly easy to repair with basic tools.
