i dont know if the 231 is but i know you can swap in a NP241 or NP241HD i dont think you want to go lighter on the t case anyway.

I don't believe they made a 231d model. The "D" designation is for Diesel...and was only used on V10/Diesel models that DIDN'T have the HD upgrade.

As far as all the tranfers cases...here's the model differences

The NV231 transfer case is used behind many V6 and V8 engines in pickups and sport utility vehicles.

The NV231HD, used in the 1994+ Ram with V6 and V8 engines, features larger bearings and a wider chain than the NV231. All versions of the 231 cases use three gears in the planetary reduction set.

The NV241 is essentially a NV231HD with six gears in the planetary set.

The NV241D is a heavier duty Dodge version of the 241, with a larger input shaft and larger bearings to withstand the torque of the V10 and diesel engines.

The NV241HD, an option on Ram 2500's and standard on Ram 3500's built after 1998, has a stronger case and wider drive chain to better withstand the shock of snow plow service, a PTO cover and drive gear, and an extra bearing to support the thrust to the main shaft created by a PTO adapter.

Just crawled under my dakota and the tag says 231D HD. Build date is 2/98 even though the truck is a 99?

The "D" designation is for Dodge. "J" is Jeep, etc.

231 DHD has a wider chain, etc. It is indeed the "heavy duty" version.
