Where is the vibration coming from?Sorry if i did not explain very well. Here is what is going on. If i have the wheels straight ahead and i accelerate from a dead stop there is a very brief light vibration between 1 and 10 mph. If I have the wheels turned all the way to the left or right and accelerate there is a more intense vibration that goes away once i continue to accelerate and straighten the wheels out. If i crank the wheels hard to the left or right and hold it there and accelerate from a dead stop it dose the same intense vibration. when i am driving on the road there is no vibration weather i am going straight or around a curve in the road. But as soon as i stop and make a turn it happens again.
Hope that explains it better.
You've got something going wrong in your drive train. I have a 2018 Forester and have no vibration at all.
