Ed, I'll look in to this and report back. I like the idea of a soft landing when the suspension gets whacked a good one. As I posit above, if my rear suspension can travel all the way up to the bump plate without a bumper in place, that would be a really hard knock and maybe too long of a stretch for the CV drive axel assembly. Those CV bearings can accommodate a certain amount of axial movement (stretching, if you will) but there would be a limit. Did I reach and try to exceed that limit? Maybe.
