Random tire thumping noise

[Cutie Pie #2]

I used to work (4 years ago) at a Jeep dealership as a parts/courtesy driver, one day I had to take a customer's Jeep Grand Cherokee back to Baltimore on I-95, On the way to the highway, the Jeep started to shake and vibrate all over the place, well next thing I noticed was the wheel rolling right by me crossed oncoming traffic and landed in someone's yard. Now I'm in a Jeep so next that happened the left front fell to the road and I had no brakes, I was able to still use the E-brake to stop, but whew I had never been so scared in my life. I called the shop and told them what had happened, next thing the guy that was working on the Jeep, was running up the road and he had all the lugs nuts in his hand, he had forgot to put the lugs back on. They then got the tire back on the Jeep and all was good, but I was not about to drive it after all that, so I didn't. Just thought I share that story with you. It's is very scary I could have been killed if I were to have been on I-95 when it had happened.
