Applications

Tech Note 1: Quality
There are not any real "upgrade" parts for the NP241DLD series Transfer Cases. It is a pretty good transfer case for all gas and stock or mildly upgraded Cummins Diesel Dodge trucks when correctly assembled using original equipment quality parts. I rebuilt an awful lot of these things before I retired and I can tell you that I never saw any aftermarket rebuild kits that even comes close to the quality and completeness of our Master Overhaul Kits. If you want to do a first-class, long-lasting rebuild, these Kits are the only way to go.

Tech Note 2: Average Life
Typically, NP241DLD series transfer cases are usually the second longest lasting drivetrain component on a 1998-2002 Dodge Diesel truck (the Cummins Transmission is #1). Average life is in excess of 250,000 miles with recommended fluid changes.

Tech Note 3: Oil
One way to kill your transfer case is to run it out of oil or with either wrong or dirty oil. My 1999 and 2001 Dodge Shop Manuals recommend 5 (1999) or 4.61 (2001) pints of Dexron II (1999) or Mopar ATF+4 (2001) in the NP241DLD. I always use the synthetic version of the most current Dexron formula. The transfer case fluid should be changed every 36,000 miles to meet the Dodge maintenance schedule. Check your Dodge Ram Truck owners manual for the specific lubrication recommendations for your year and model. Excessive horsepower is another way to murder your Transfer Case. From what I have seen, NP241DLD reliability starts to really suffer when input torque exceeds 700 lb.-ft.

Tech Note 4: Causes of Damaged Housing
Cracked or broken housings are usually a result of:
Accident Damage: A good whack on the front axle will push the axle and driveshaft backwards.
High Centered: Off-Roading or sliding into a ditch without a skid plate.
Loose Mounting Nuts: Make sure the six mounting nuts are tight.
Stretched Chain: Not real common, but a loose chain will wear through the bottom of the case.
Run Out of Oil: If the bearings seize, your Transfer Case is toast.

Tech Note 5: Clunk
Contrary to popular belief, the Drive Chain cannot cause a clunk or contribute to "slack" in the drive train in 4x2 mode. The chain is only under power in 4x4 mode. You should always replace the chain when doing major transfer case service, plus you should inspect the sprockets for wear on the teeth. If you can feel teeth wear with your fingernail REPLACE BOTH the SPROCKETS and CHAIN!

Tech Note 6: Stock Components
All 1998-2002 NP241DLD Transfer Cases will have a 32 slip yoke rear output without a speedometer drive, left side chain driven front output, front CV flange and manual shift engagement. All 1998-2002 NP241DLD transfer cases will also have a 6-gear planetary 2.72:1 ratio low range. The NP241DLD uses a 1-1/4" wide drive chain and does not have a provision to mount a Power Take Off (PTO). The NP241DLD was only used on Ram 2500 trucks. 1998-2002.5 trucks with vacuum controlled Central Axle Disconnect have a transfer case mounted vacuum switch, which controls the front axle disconnect system. 2002.5 trucks without CAD will have a shift indicator switch. All models are synchronized for 4x4 mode engagement except assemblies ending with the letters AD.
