look at the transfer case,theres a fill hole and a drain hole both with bolts to take out. You can also search on youtube to see a vid.
Transfer case is lubricated by the transmission fluid.
Well this is a fairly straight forward process. You're going to have to remove both drive-shafts at the transfer case, they can hang there. Then remove the electrical connections at the speed sensor and the 4 wheel actuator. Drain the fluid out of the transfer case. Be careful, there will be fluid coming out between the case and the transmission when you get the bolts out of the transfer case. I believe they are 13mm headed bolts. About 6 of them. If your stout enough, you can separate the transfer case, let it swivel down from the alignment dowel pins and slide it out without the use of a floorjack. The case itself isn't very heavy at all. Good luck.
Remove all wires attached to the transfer case. Remove the driveshafts. Drain the fluid out of the transfer case. Place a transmission jack under the transfer case. Unbolt the transfer case from the transmission. Unbolt the crossmember the transfer case rests on.
Transfer cases are not like Transmissions they don't have drain pans. They only have drain and fill plugs. Transfer cases do not have filters either.
yoke , you must mean the rear prop shaft including U-Joint yokes. easy, drain transfer case (bottom plug) unbolt u-joint flange at rear axle. prop shaft just slides out of transfer case. 4 bolts and and 1 plug.
under the jeep your transfer case remove the bolt with an Allen hole in it with and Allen socket. the fluid should run out of the hole. if you remove the bottom bolt you will drain your transfer case. if you remove the top bolt then you will be able to check it and will not have to refil it.
there probrably aren't any bolts it is most likely a universal that you need to remove to release the shaft from the transfer case
NO. If you keep finding yourself ADDING transmission fluid often and you have no leaks but the transfer case is over full then you need to remove the transfer case and replace the seal in the transfer case where it bolts to the rear of the transmission.
The one that fits.
remove the bolts at the frame rails
