I'm planning on going on a trip and it's about a two hour drive. I've been to pepboys and they told me I have to replace my control arms (left and right) and he told me to stay off the highway. But my steering wheel also shakes when I slow down at high speeds. I'm wondering if I'll be alright if I make this trip? I'm not too worried about the control arms but I am more concerned about the rotors when it comes to staying on the freeway for two hours. HELP!
