If it's a 4 wheel then you have to remove the front diffrential case to the all-wheel drive, if it's not then you will drop the oil pan and look toward the rear of the motor which would be toward the transmission and you should see some bolts at the rear of the crankshaft. remove the bolts and you shold see some rubber. go from there.
