putting in a sye and replacing the oil seal for the front output shaft.so i repaced that but my chiltons is also calling for seal washer right behind the nut that holds on the yoke.i did find a round peice of rubber that had been pretty much destroyed behind the nut.no autoparts store is showing it in the computer neither is the dealer or the local driveline shop.anybody run into this washer?can i just use a rubber washer from the hardware store?i also dont see how i can torque down the nut with the washer behind it.
