I have an 06' Civic and a few months ago I ran over a cement divider in a parking lot and just yesterday I ran over the curb. Both times I scraped the bottom of my car and never had any real problems until today I got in my car and noticed my car vibrates really bad when I put it in reverse. I've noticed it doing that in the past but today was more then usual. I know you'd have to see the car to diagnose what's wrong but any ideas what may be wrong? What'd cause it to vibrate in reverse? This is my first car and I'm new to all of this lol. Any suggestions or input would really help. Thanks.
