I believe what you have is a limited slip rear end, that's 1 of 4 keepers you have that keeps the little clutch plates stationary, if that fell out I think you have a very big problem in the near future if not fixed soon. The clutch plates/disks (whatever they are called) have ears that sit in the grooves of the keepers to hold then stationary so either the ears bent on those plates or something of a bigger issue happened for that keeper to fall out, if all of them hasn't fallen out already?
