Front Suspension problems of the 2001 Lexus RX300

2001 Lexus Rx300 in town driving all of a sudden the wheels seemed to be locked up, any speed above a crawl was accompanied by strong vibrations and loud noise. Barely made it home with emergency flasher on and crawling along. After parking the front right wheel looked cockeyed and an upper rod to the right front wheel had detached. Will get aaa to take it to a Lexus dealer tomorrow. The car has less than 60k miles. Just glad I wasn't on a freeway or far from home, but was surprised and shaken by this.
