transfer case determination
 
how do i tell what transfer case i have? I have a 94 ZJ laredo with
the I6, with 2hi, 4hi, neutral, and 4lo

NP231 "Command Trac"
http://www.novak-adapt.com/knowledge/np231.htm

It's a "part time" system. So you only want to use 2H on hard
surfaces. 4H and 4L are for offroad/dirt/gravel only and will
damage the xfr case if you run it on hard surfaces.

You have the NP231.

Never use any 4WD selection on hard surfaces where the tires can get a good
grip. 4WD is intended for traction challenged conditions only.

Re: transfer case determination
 
Yes, it should be. Either that or the NP232. The difference is that the 232
is a Full time system with a Center Differential of sorts, wheras the 231 is
a Part Time system that has no center diff.

As you drive, the differentials in the axles handle the speed differences
from left to right on the same axle. In 4WD, the front and rear axles travel
much different lines (arcs) and the speed of the front and rear axles are
vastly different. The Center Differential accomodates this difference,
without it the transfer case takes a beating and eventually fails.

Re: transfer case determination
 
Mechanically, the NP231 and NP231 use very similar gear cases. The NP231
has a planitary gear setup for high/lo range and the NP232 has a
diferential gear in the same location.
