Whenever I hit a bump or little marker on freeway steering wheel shakes rapidly and thens goes back to normal. I know my struts are bad could that cause the rapid shaking. or anything else i could check. Also Have a bad motor mount on the front side but im not sure if that would cause that kind of vibration. The car just feels loose. It drove better when I had it lowered more.
Check your tie rod ends. Jack up the car and grab the wheels at the 3 and 9 o’clock position and see if theres any play in it. And by all means when you know something is bad on your car fix it. Dont put it off and let things build up.
