I've had a similiar problem with my car for a long time. Its driving me crazy. It originally started when I changed the left CV axle w/a rebuild. I've since changed it with a new one and it still shakes.I don't get any clicks though. I found that the left inner tie rod is sloppy on my car so I'm gonna change it.Hopefully that will cure it.
my car shakes, runs warm sometimes and the AC shuts down.
