Long story short. My car shakes/vibrates when going over 40mph (even the steering wheel). It has nothing to do with my brakepads,tires or rotors etc.. I've replaced the right side driveshaft & still having the same problem. I took it back to the shop, upon diagnose - found lower control arm bushing cracked but it's not 100%. The shop recommend to get second opinon from another shop. I then took the car to Honda Dealer, they did a diagnostic & for me to replace the left side driveshaft and recheck. I asked the Technician about the arm bushing but he stated didn't find nothing. At this point I am so frustrated not knowing what is wrong or who is right. I need some answers.Thank You.
