PDS shock breakage?


I was approached by a few people at my local MX track (open practice) that asked me if my shock had broke yet (1998 KTM380SX). When I said no, they said "it will". Something about the end unscewing from the shaft and coming apart. I've heard of this on the newer bikes, but is this a concern on the older bikes? If so, what can I do to fix it?
