Hey all you car experts out there...I need some info before going to
the garage and hoped someone could help me out?

I have a 2002 Ford Focus.

I was recently rear ended (not a major accident)a nd now when I drive
my car over 65mph the steering wheel starts shaking back and forth and
I feel if I were to go any faster the car would just fall to pieces!

I know I need to get it to the garage to have it checked since the
fender bender, but I want to know what the problem could be before
hand.  

Also, is it dangerous for me to be driving the car?  I travel the
interstate everyday for work and would hate to be one of those
stranded people we all see on the side of the road during morning rush
hour.

Thanks so much for any help anyone can provide...I would REALLY
appreciate it !

Happy Holidays
