Removing The Both Driveshafts

You have to start the process from this point. Driveshafts [rear and front] are the first things that needed to be unbolted first. To remove the rear driveshaft which is placed on the rear pinion, you have to remove all of the bolts using a wrench and then pull the shaft. If you find the driveshaft seems stuck in the pinion yoke, to get it out you need to give a gentle shock using a plastic or rubber hammer, and then apply a little penetrating oil, and finally pull out the bolts with a large screwdriver.

The front driveshaft is differently held in place by a boot from the transfer case. Now you have to take a close look at the band that helps the shaft to maintain the position and remove it from its place. Finally, unbolt the shaft from the front differential. This made the whole shaft come out of the transfer case.

Draining The Transfer Case Fluid

Draining out transmission fluid is the next step of the whole process. It can be done in two different ways- either remove the drain plug and let the transfer fluid come out or remove the entire transfer fluid pan situated at the bottom of the transfer case. Which one of the methods is convenient for you depends on the type and model of your vehicle. But if you follow the first way, don’t forget to take out the fill plug, unless you may not find the way to refill the fluid back once your job is over.

Removing All The Sensors

Removing All The Linkage

In most vehicles, you may find several linkages that are connected with the transfer case such as, neutral safety switch wiring, cooler lines, electrical harness, and shift linkage. All of them must be cut off to draw out the transfer case. But if your vehicle is an electric-controlled unit, then you may not find all these arrangements there.

Unbolting the Case

Before doing the final step, now it is time to unbolt the transfer case so that it would be easier for you to take it off. While doing the job you can find that the transfer case is fixed with the back of the transmission using six 15mm bolts. All you need to take a ratchet wrench that will fit with the bolt perfectly and help all of them to come out quite smoothly.

Removing The Transfer Case

After following all the steps one after another carefully, it is time now to wrap off the job. Here you need to remove the 4 bolts and the lower protector of the transfer case as well. After that, you have to cut out the transmission assembly as well as the 8 transfer adaptor rear mounting bolts. Finally, pull the transfer case up and then pull it out from the transmission very carefully avoiding the dropping threat. Therefore, a jack must be taken for use for this purpose.

The Final Words
