In 1987 my wife and I were taking my parents for a month long tour of the
west. At one of Yellowstone's service stations I had the tires balanced on
the van we rented. After I picked up the van and we had almost exited
Yellowstone I heard a noise from the right rear area. Looking the van over I
discovered only two lug nuts on the right rear wheel. I took one lug nut two
other wheels and stopped in West Yellowstone at a NAPA store to replace all
missing nuts. Check and double check any work done and don't think all
people are competent and honest.
