I HAVE THREE QUESTIONS:

1)Whenever I run over small bumps my steering wheel shacks and it knocks my car out of balance slightly and I feel it in the steering. What is the issue? I have a 2007 Grand Prix.

2) Whenever I am drive 70mph or higher on the freeway, my car drifts to the light slightly but not a lot.

3) Whenever I hit my brakes I hear wo wo wo sound and they are brand new brakes and rooter, only had them a month and a half.

I have a alignment and balance already probably 2 months ago but my car just still drift off slightly when I am driving on the highway. Before I got the alignment and balance my car was drifting all the way to the left and he had to fix something else to but I forgot what it was, I thinks it was bearing on the left side. No the brake was not making that sound before or after I got the new ones, just started a little after.

No I have never replaced the struts and the slight drifts I am having now is to the left. I think it is the struts so I gonna try that and another alignment. How much does that usaully cost? And are there 4 struts for each wheel. Finally question I know I am being a pest but I just really wanna get me car together its my first car. Another thing is that I can feel like grinding or knocking in the acceleration pedal when I am driving, do you have any idea about that?

One strut for each corner so 4 total. Shop around for a deal tire stores run these. @$250 for fronts. The noise on acceleration maybe CV joints so have thoes checked.
