So I purchased a 94 Cherokee about a year ago and the speedometer never worked. According to the guy I purchased it from he said that he replaced the transfer case with a better one and that I needed a new gear for the speedometer to work.

How do I go about finding out what transfer case was installed to find the correct speedometer gear I would need so it starts working again?

I have no contact infor with the previous owner now so I can ask him what it was he installed. Everything is still stock (wheels, tires, lift)

Thanks everyone!

 

The Tcase should have a red tag on it that will tell you what it is.

 

you've most likely got either a 231 or 242. does it have part time and full time options?

you will probably need a long shaft 31 spline (if i recall). you can get one from the dealer, but for probably 25 bux.
or go to the wrecker and pull one from a case. either 231 or 242 should have the same gear.
it's easy, just remove the bolt/finger and pull the speedo cable housing out. the gear is under there and just pulls out to remove it.

 

shift pattern for a 231 is 2H-4H-N-4L and shift pattern for a 242 is 2wd-4 part time-4 full time-N-4LO easyest why to tell which one you have

 

or just simply use a gps, it's more accurate anyways.

if you have larger tires, you'll need to find a chart and order the correct speedo gear from the dealer.
there are many charts on the interweb.

 

I use a great app for my android phone called speed view...... Uses gps and is very acurate, my 32's make the xj speedometer off by about 7 to 10 mph. If you have an android phone buy a mount for it and dload speed view, its free.

 

klbsa - hahaha i already use that app now on my droid phone =)

jeepxj19 - the shift options on are 2H-4H-N-4L

Thanks for the info guys, i will get under there and have a look tonight. Much appreciated!!

 

You have an np231 then.

 

how many teeth should it have?

searching google returned losts of results but couldnt find something that stated how many teeth it should have. jeep is completly stock (yes i know that is sad, but soon $$ and fun will come)
