Im trying to figure out how to replace a transfer case on a 97 gmc sonoma

What exactly do you need to know?? This is a very straight forward job, all that is really required are common hand tools and perhaps a star/Torx female socket for the U-Joint bolts U clamp nuts and very strong arms or a helper is great. Of course you will need to jack the truck off the ground as far as possible or use a car lift (preferred method), Use jack stands to support the truck, it really hurts when a car or truck falls on you! Rememeber safety first!! On a car lift I've removed a transfer case in less than 20 minutes to replace a seal. What exactly do you need to know??
