My car has been acting strange for the last couple of days. Got real bad today. I try my best to take care of 'er but with 2 kids & always on the go..I'm afraid it's impossible. Okay. Here's what's happening. I can only describe what's happening as if I am behind the wheel of my car, for better understanding. When I am driving the car straight & start to get a little more speed (say 35-45) she will start knocking loudly and I can feel 'er shaking in my steeringwheel. When I turn the car on winding road to the left or right she'll stop til I am driving straight again. Now I can't drive 'er..I'm too afraid too. I have kids in school that I drive to school and pick up everyday, work, Girl Scouts meetings, grocery shopping & many other things that single moms do. My hands are full as it is. I don't have much money & don't want to spend an arm & leg for whatever part(s) I need to fix 'er up so that I can drive 'er again. What could it be?! I'm told that it could be the tie rod or motor mount. Which is it?
