Well, not me but a buddy changed his oil, let it run, checked for leaks... everything went great. Well, hopped in, backed it up, and went to pull it from between two spots to just one spot... forgot to move the oil pan, drove over it.. At that point I laughed and walked away.
Me? well, when I first got the Jeep, the previous owner drove it like an ass and the U-joints were almost shot. So my buddy was driving it to Autozone cause he wanted to take it for a drive, I agreed. He tried to drop the clutch and smoke the tires... worked fine, beautifully actually, then I told him about the U joints. He did it again, not so much luck this time. We were across from teh store at this point, did the U joint in the lot, went to drive away... Ends up he broke the tab off the yoke that holds the U joint caps in so it fell apart right away again.
Ended up using a U joint clip and JB weld and got it home that way, actually drove it to and from work for a wk or 2 fine, then I decided it was time to get a new yoke anyway and thought I could show up my buddy who left a "nice" one legger near my house... apparently my yoke/U-joint shot out from under the Jeep in about 20 pieces with taht one... I had to walk to work for a week till the parts came in.
