Ball diffs used on carpet in on-road for decades. May not be the best application for a 2wd buggy but if they are set correctly, which isn't difficult they work fine and don't just self-destruct. The XRay manual has good instructions on how to adjust the diff. If people ignore the procedure the issue is with them, not the type of diff. If it starts to bark, it typically needs adjusted, not completely torn down.
