You guys don't realize the risks you take everyday going out on the road. Some cars put pressure on the lower balljoint socket, if that socket fails that joint and the whole spindle assembly comes loose. That happened to my wife's Honda Accord. Fortunate for us it happened right as we pulled in the driveway, so I was only going 5mph. The whole spindle assembly came loose, pulled the axle out of the transmission, and the front of the car was sitting on the tire, it had tucked itself back up in the wheel well.
No warning no clunking, always passed inspection. I had noticed the steering was a little stiff, but didn't realize what was going on. If we were buzzing down the highway and it happened it would not have been good. I had replaced all the balljoints at about 140,000. It has 248,000 on it now. just happened a couple of months ago.
