While driving on a level flat road at approximately 25 MPH, the front right lower A frame assembly snapped and caused the front suspension to drop and the resulting drop caused the front tire to be ripped from its rim. As a result, I briefly lost control and crashed into a parked vehicle. Had this occurred at a higher speed the result would have been disastrous! The lower A-Frame is a thick cast aluminum structure that is approx 11/2" thick where it cracked apart.
