My 7 disc lasted about 6 years maybe 6,000 miles. My new 5 disc is great. No rattles and very rarely stalls when I put it in gear cold. I paid $375 for the new 5 disc with the broken 7 disc trade in. So it was not that bad of a deal.
Did you say your muti disk vig doesn't rattle at idle thats a first...LOL
