ok on my awd i need to seal my transfercase yoke and thats a pain in a ass i helped my friend on his laser awd. and 5 speed is stronger then autos jus because they are much more fun. and make sure no rust thank god mine has none, 6,4 combo if your droping your own moter then make sure its a 4 bolt rear. make sure nothing is leaking under the car and if has a motor then check for any oil on top, blown hoses etc. and if there is anything else i missed im sure i can come up with more, oh and make sure car does not overheat!!!!!! i wanna blow mine up right now because of that but im having a blast pulling off the head
