Default Swiss over engineering

While upgrading my NP249 to a NP242 i decided that checking level with my finger
while having to remove a drain plug did not reach my expectations for my ZJ

Therefore i choose to instal an oil level indicator to see the level in my
TC at any time of my choosing w/o having to unscrew anything

Milling flat surface

Drilling 20.5mm

Tapping M22x1.5

Tapping M27x1.5

Finished machining

Visual gauge installed


I used Metric because both Drain Plug are in metric size and
also because i already have both the tools in stock in my workshop

To have the oil level at the mid of indicator it will raise the level 0.45" to be exact
this will not cause any spill by the way

The indicator come from ELESA :
GN.37707 / GN 743.1-18-M27x1.5-A
its made out of aluminum and can be used in a range of +180 / -20
http://www.elesa.com/scheda_en_2_7367_1_4.aspx

the next step is to drill the lower drain plug to fit a temp. gauge in it

At this time my car is setting on my drive way

On going overhaul of the axles
waiting on the delivery of Aussie lockers for both axles

NP 242 waiting for final assembly


Both my axles did make noise the previous owner did not check levels
they where almost dry of any oil, all bearings in both axles need to be replaced

Did the 249 to 242 swap the other day. Still have a bit of work to do on the linkage but I have 2wd and have 4wd high.
I removed the VIC and did the wire disconnect/connect thing (man what a time locating the two black plugs) but my VIC says FULL TIME. Any ideas on what I may have done wrong? Where do I get the shorter linkage the 242 needs.
Oh, this is a 98 GCL with the 5.2 and automatic.

Which TC switch did you put on it ?
If the 242 come from a GC with 4L its ok
but if it come from a Cherokee you have to use the one from your 249
You shall use the lever that was with the 242 an
then adjust the length of linkage

I have a 97 limited 4.0 with the 242 that I want to swap to my 97 limited 5.2 with the 249. Will this be a direct bolt in with no shaft modifications?

I would like to know this too. I heard 96-98 are all easy direct swaps

As I resurrect a dormant thread, I have a 98 Tsi with a 4.0 and a 249. 207k and the T-case is binding. Seems pretty easy swap if you can find a 242 with the proper tailshaft. I read that the 93-95 242's came with an internal slip yoke like my 249 and the 96-98 242's used an external SY which would require more work. Can someone enlighten me as to which 242 to shop for at the local salvage yards?
