I have a 99 ZR 600 EFI.  I have replaced 2 front driveshafts in the last two weeks.  The last one broke last night.  I was riding on the grommed trail.  I did run over a stump that was even with the trail.  I was doing about 30 mph.  All I felt was a thump, I have heard the same noise often driving through powder or a frozen section of bog.  Wondering if there has been any problems that anyone has heard of or were conditions just right enough for it to fracture.  The one I replaced last week, stems from a similar incident, but appeared to have been broken for a while.  The last one failed inside one of the drive wheels.  Last night it broke directly in the center of the shaft.
