For the most part, all transfer cases, regardless of the vehicles make, look alike. There are, however, a couple of distinguishing factors that will allow you to identify a Dodge transfer case. The first thing that you need to understand is that there are at least five different Dodge transfer case versions. They are the NV231, NV231HD, NV241, NV241HD and NV241D. Each of these transfer cases is used in a different type of Dodge.
Step 1
Know that NV231HD can be found in 1994 and older Dodge Ram pick-up trucks that are equipped with either the V8 or 6-cylinder engines. By comparison, the NV231 transfer case is also used in many sport utility vehicles and pickup trucks of the same years that feature V8 and 6-cylinder engines, as well.
Step 2
Distinguish the main difference between the NV231 and NV231HD transfer cases. You can accomplish this by knowing that the HD version has bearings, which are larger and a chain thats wider than that of the NV231. The Dodge transfer case is made up of aluminum, as are the retainer, extension and gear cases.
Step 3
Be aware that engine torque is transmitted to the front and rear propeller shafts by drive sprockets and a chain thats interconnecting. Needle and ball bearings support the front output shaft, input gear and main shaft. Other components on the transfer case that will aid you in identifying it as a Dodge transfer case are the components that make up the synchro mechanism. These include the synchro hub and features two springs used for retaining; three struts and a sliding clutch. These components allow for shifting between 4-high and 2-high ranges, while the vehicle is rolling.
Step 4
Understand that, except for a few differences in dimension all models of the Dodge transfer cases appear to be almost identical. Distinguishing between the different models is achieved by an ID tag thats attached to each transfer case.
Be aware that this tag can be found on the rear portion of the transfer case. The tag provides information such as the assembly number, model number, low range ration and serial number. You will also find the date that the transfer case was built, in the serial number.
