Can anyone tell me if there is an O'Ring type of set up on the back of the transfer case on an '03, where the driveshaft meshes up with the output shaft. mine seems to be leaking through the yoke and decorating the bottom of my rig with expensive ATF, buddy of mine seems to think we can just pull shaft and fill the hole that goes through yoke with some silicone and call it done, anyone else? TIA!!
