My 1996 Firebird shakes and vibrates a bit when I drive 55-60mph- what needs to

[Fatdude427]

be done to remedy this? All of the tires are either new or are relatively new, so that isn't the problem.

The alignment hasn't been done in a long, long time.

Will that correct the vibrations?

What else might it be?

If the tires are New were they balanced when they were put on? are all of the weights still in place?
if it has not been aligned that may help but you could have a bad tie rod end or a balljoint going out or even warn bushings in the suspension ..
you need to have it checked out by a pro..
