We noticed our belt was fraying just slightly so we went ahead and replaced it. When we were putting the new belt on, every time the VX is started, the belt jumps off alignment on the fan pulley - just slightly. It is off by maybe 1/4" but thats enough for us to see that it may cause the new belt the same problem. Anyone have any ideas? She's got almost 107,000 miles on her with NO problems. *knocking on wood*
