I have seen it happen twice now and not ptiing down your work by any means but the out of three I have seen 2 of them were not installed correctly and the u joint cup was not totally in the pocket and the u joint cap was tightened down so it never sat flush with both sides down, the 3rd on had too much play in the yoke and just a bit wore out so the u joint would actually slide back and forth and hit one side then slide the other way until the tab broke off other than that the only thing would actually be that maybe a needle bearing was out of place or damaged per factory, as defective.
