Loosing a wheel
I almost lost a rear wheel on my 89K5, the passenger rear tire had gone flat and the jack i had wouldn't quite jack it all the way up. I managed to wedge the spare on, but didn't realize that the lugs weren't really on correctly. About 5 miles later started hearing 'ker-chunk ker-chunk) from the rear. Broke off 3 of the lugs. Tightened down the rest, and went VERY carefully to the local firestone. When I was about 17 however, someone thought it would be REALLY funny to remove the lugnuts on the rear of my duster and then put the hubcap back on. That wheel came off doing 60 down a 2-lane highway, and the axel promptly dug into the ground and spun the car around about 3 times. I hit a mailbox, the ditch, and another car with the loose wheel! Scared the fire outta me. It took us 15 minutes to find the wheel (nearly 1/4 of a mile from where i stopped) another 10 minutes to find the brake hub (which was cracked in 3 places) and another 10 minutes to find the hubcap. We never did find any of the lugnuts. The lugs were pristine, we had it towed, got a brake hub and new lug nuts, and kept on driving it for another 2 years. Folded up the rear quarter really good, but otherwise didn't do any damage to the car.
