Bummer. I would recommend getting the factory service manual for this
vehicle or the Jeep Conversion Manual from Advance Adapters
(http://advanceadapters.com)
so you can be absolutely sure what you have,
before buying stuff that might not fit. There is a round metal tag about
as
big as a half dollar, fastened to the back of the transfer case housing.
It
should have the model number on it. I haven't heard of a NP232, of course
that doesn't mean it doesn't exist. As Will says, there were a number of
different transfer case input shafts, not only spline count but also
length.
It is essential to get the correct one as it must mate correctly with your
transmission output shaft. The Advance Adapters manual will help you
identify this part. They should also have various versions of the part
for
sale.
Do you have a SelecTrac case in your XJ? That would be one, with a full
time four wheel drive mode in addition to 2HI, 4HI, N and 2LO. The NP231
only has the four speeds listed above, making it a "part time four wheel
drive" model. The full time SelecTrac model will have additional options
such as "Full" or "Lock". The ****ft pattern will be printed on the
Transfer
Case ****ft knob, overhead visor, or inside the glove box. If so, the
NP231
is a possible replacement but as has been said drive shafts, mounts and
the
crucial transfer case input shaft may be different.
You should be able to buy a new housing from the Jeep dealer, if for
example
the chain just jumped the sprocket and poked a hole in the case.
Availability and cost might be problems, but if the chain and the case are
the only unusable parts it would be reasonable to think of rebuilding what
you have now. It won't hurt to disassemble your existing transfer case
and
take a full damage inventory. You probably need a manual for this.
On the Advance Adapters site they have transfer cases for sale with slip
yoke eliminator. These are NP231 and NP241, both part time transfer
cases.
If you plan on keeping this vehicle for a long time, the available
possible
upgrades to the transfer case are worth considering. A slip yoke
eliminator
isn't strictly necessary on a Cherokee, but it won't hurt and you would
have
to have drive shafts fabricated anyway to use a different model transfer
case.
Cheers,
Earle
