I found a donut looking metal object hangin out loose in my transfer case (np231) and cant figure out if it is a part of it or not. I took apart my transfer case after my 4x4 was making awful sounding popping and grinding noises. If someone could tell me if there is a 1/8" thick by 2" circular abject that goes inside the transfer case somewhere i would greatly appreciate it. I will take a pic if it helps.
PS- when i first found it in the transfer case after cracking the transfer case in half, it was covered in thick grime and tiny metal fragments. All my TC fluid was black when i drained it.
