hey fellas my 99 sport recently developed a gnarley clunk and clatter while in motion. Today I started looking for a rebuild kit since the motor and trans are basically brand new, well I was going to order from drivetrain.com so I could get a Tcase saver at the same time but when I went to the kits it lists 2 options

I've done a bit of searching and cant seem to find my answer, since i dont want to leave my truck immobile while I'm waiting on the mail man I don't want to take the case out to check bearing size

anyway which kit is the proper one ? the one with the 16mm input bearing or the 24mm input ? NP231d transfer case.
thanks guys

 

I *think* standard is the 16mm bearing.... and the 24mm bearing was on the 231DHD case. (which also had a wider chain.)

 

okay, I've checked the manuals and all the other stuff and cant seem to see anything to verify. hopefully someone else can chime in with more confidence about your statement. Nobody local has the parts, or even offers a rebuild kit, so I'm pretty much stuck buying online

 

Next best is call those stores directly...

 

closed on saturday, tried that first, I figured since I cant get answers til monday I'd post here and see if someone might have an answer before I call back

 

Lots of info on quad4x4

still not finding what I'm needing, I suppose I'm going to have to dig into it

 

Which Bearing one do you need the measurements on i have my NP231HD apart right now for a rebuild. I went down to my local parts house and asked for a rebuild ket for the t case for my spec of truck and they gave me the kit.

 

I think all second gen np231s in the full size rams are the HD variant. And the Dakota and the like got the standard version.

 

after measuring the input bearing it looks to be, about 15/16in ~ 24mm
