Ive recently noticed a faint whine coming from the rear primary area. Doesn't matter if its in gear, sitting or moving it seems the same. Drained the primary oil which looked OK for 5K miles and poped the cover to have a look inside. Using a long driver with light pressure under one of the diaphragm bolt heads and the edge of the primary cover I found the entire clutch basket/ring gear/plates etc assembly can be easily moved up or down about an 1/8 of an inch. Theres a large roller bearing pressed into the inner primary, Im guessin this is headed south??
