Potential problems with the NP241 Transfer Case

This unit can have issues with case failure caused by out of balance driveshafts, at the first sign of vibration it is time to get the driveline inspected, repaired and high speed balanced before case failure. High mileage will contribute to failure of the range hub, range fork and input shaft, this failure is exhibited by the unit popping out of gear. Another problem associated with the NP241 transfer case is the snap ring on the rear output shaft failing, this can be easily repaired by installing a specially designed snap ring or snap ring retainer, it is a good idea to fix this problem before you have a failure. Excessive slip yoke wear can cause leakage of the fluid, watch for signs of fluid on the driveway, you can replace the rear extension housing bushing, seal and slip yoke to fix this problem. When researching the NP241 you will see a lot of chatter about wide input bearing verses narrow bearing, here is what you need to know: the wide bearing is .940 and is part number BD50-8, the narrow bearing is .630 and part number is 6010N. It is a good idea to check your input bearing number prior to ordering any parts.
