I can add to this post.
I have an old car that's a little weird, anyways there's a guy in town that specializes in working on this old car. It had an engine problem, the car is only worth about 2 grand.
I picked the car up after him working on it for months, and drove it across town to my house. When I got close to the house, I started hearing some noise from the wheel, and feeling a little vibration.
When I turned to pull into my driveway, the back wheel fell off because he didn't tighten the lug nuts.
