Our deal when he got the Jeep was that if we wheel it eventually we will break something, I helped a guy with a stock car in high school and know that eventually something will break. My Dad that rode with him that day had drag raced back in the 50's also knew that. As long as he isn't out doing stupid stuff were cool with breakage.
Even though the weld seemed perfect we removed the driveshaft Saturday night just to be safe. One of the best moments of the trip was seeing my Dad (age 72) and my Son (age 19) under his Jeep taking the driveshaft out. They wouldn't even let me help!
By the way, the driveshaft has been retubed, balanced and is back in the Jeep. It was only one hundred thousandths out of true but the shop said they only allow ten thousandths.
