How do you change the fluid in the transfer case of a 1997 Jeep Grand Cherokee?

Answer 1

Some transfer cases might be different but there should be two large bolts/plugs on the rear of the transfer case, one about half way up and one on the bottom. The bottom one is for draining and the top one if for filling it back up. It is pretty tight manuevering to fill it and usually makes a mess trying to get the fluid back in. It should be filled just until it starts to flow out of the fill hole and use whatever fluid the dealer or parts store recommends. There is also a small filter inside the transfer case that doesnt really need to be changed but will trap dirt and stuff once inside the case and can be cleaned. I've changed two t-cases and drained them both before taking them apart and they still had gunk stuck in there. The only way to clean it is to take the back half of the t-case apart but unless you have done similar projects or can find a description online of how to do it i would not recommend it. Even if you dont clean the filter the t-case will probably be the last thing to go in a drivetrain.
