When I drive strait on the freeway my car handles poorly. feels like one wheel kind of wanders. But on the streets it corners hella good. Do I need an alignment or could it be my suspension?

 

If you have too much "toe-in", your car will be very twitchy on the highway, but go-kart like turn in on slower corners. Conversely, too much "toe-out" will cause a lazy feel.

If there is a problem with your suspension (ball-joints etc) then you cannot get it alligned. Therefor, the best thing to do is take it to a shop that does FREE inspections - most suspension places do. Then, they'll tell you if anything is worn or broken. If so, fix it and get it alligned. If not, head straight for the allignment shop.

You're going to want to go somewhere that does a 4 wheel alignment too...
