I have an 02 tacoma, and before my SAS, my rear u-joint on the drive shaft went out for the second time, but I had to drive on it for a few days. Since then, my truck has consistently been leaking oil. I know that vibration can ruin gaskets, and if there is a gasket between the transfer case and the transmission, then that's probably the culprit. The only weird thing is that the leak is ridiculous, then entire transmission, transmission crossmember, and transfer case are coated in oil, and due to driving on the interstate, the wind has caused the oil to spread to the rear axle, etc. There is even oil on top of the transmission (!) Has anyone had this problem, and is there a gasket between the transmission and transfer case. I know that Heeps don't have any gasket between the transfer case and the transmission, but that's not saying much. Anyway, thanks.
