great awesome ....thank you very much and after some debate i decided to keep the old beast for a while longer ....i dont suppose you know a way to find out which gearing the rear has do you 98?....i had some friends that i was able to stay pretty close to on the highway ..at excessive speed say they believe it has airplane gears what ever that means

Your 4wd so I imagine your tires are 265/75. At 70mph with 4.10's you will be at 2286RPM. At 70 with 3.54's you will be at 1973RPM. That's the easiest way to tell.

mine also has a sticker in the glovebox door. shows my 6-holer to have 5200# front D60 and 3.55s

As posted previously, my truck still has the sticker on the glove box door... great source of information. Also check for any original paperwork.

you can also jack up the rearend of the truck and mark the driveline and tire and rotate the tire one full revolution and watch the driveline. If the driveline turns 3 turns and the tire will turn about a half turn then you should 3.55 then if the driveline turns 4 turns to one its a 4.10. I believe thats the way to check or your axle should have any ID tag on it that has the ratio stamped in it!!! Dont quote me on this but i think this right.

Thatll work, for sure. But I'd bet there's a label in the glove box... :)

There should also be a tag on the rear end that has the gear ratio too.

if you are going to jack the wheels up and count the rotations, you can also find out if you have an open or limited-slip diff. if the wheels spin the same way, you have a limited-slip. if they spin opposite, it is an open diff. but first check for the sticker under side of the hood or tag on the diff cover. it seems that diff tags often get removed(mine was when i purchased @125k). i think the dealership should be able to look it up from your VIN number also.

no sticker in the glove box ..no original paperwork ..i am the third owner ..I think... no tags on the differential havent tried jacking it up yet to rotate the tires pretty sure i have a fully locked diff though i can hear it in the summer time when the windows are down and i make a turn the tires start skipping.

Light duty transfer case. Don't worry, it's still pretty tough.:thumb1: The heavy duty unit only has a wider chain and a larger tail shaft to make it stronger.:thumb1:

There is a little round tag on the back side of it that tells you what it is. Is will say either 241ldl or 241 hdl.:thumb1:

Prowelder you have the letters wrong

they are

NV 241 DLD= Dodge light duty

NV 241 DHD=Dodge heavy duty

Dodge W150 and W250 trucks (except Cummins Diesel models) from late 1987 to 1993 have the two speed, fixed rear output yoke, NP241, chain drive aluminum transfer case. All 1994-2002 Dodge 2500 and 3500, 4x4's are equipped with NV241 transfer cases and slip yoke type rear output shaft. Dodge 241's have a planetary low range ratio of 2.72:1. There were numerous design changes in the 241 during its production life making parts selection a bit tricky without the transfer case build tag. Starting in 1994, the stock 2500 transfer case was the NV241DLD (Dodge Light Duty). Optional on the 2500 and standard on the 3500 was the NV241DHD (Dodge Heavy Duty). 1999-2002 Ram 2500 and Ram 3500 4x4 trucks with the High-Output Cummins Diesel NV5600 6 speed transmission use the NV241DHD. 1994 to 2001 Ram 1500 models can have either a NP231, NP231HD, or NP241 transfer case depending upon the year, engine, and transmission combination.

The NP271 manual shift and NP273 electric shift, chain drive transfer cases are found in Ram 2500 and 3500 models effective for the 2003 model year. These transfer cases feature larger rear output shafts to handle the ever-increasing power of Dodge factory engines. The redesigned 2003 Ram 1500 debuted with a re-worked NV241D transfer case that is not interchangeable with prior models
