we'll take a look at the parts involved in the installation
of Tom Wood's Short Shaft Kit. You'll find that this
project demands more in the way of mechanical confidence,
than it does a shop full of tools. Although, for the
novice, cracking open a transfer case may seem very
intimidating, one can take confort in knowing that its
a fairly straight-forward procedure with common hand
is our 231J transfer case. As far as I know, the accordian
boot and the sealed output bearing housing are the only
visible differences between it and the regular 231.
As far as Jeeps go, this transfer case is common to
later model. TJs and XJs.
is Tom Wood's Short Shaft Kit all laid out on the table.
You will have to purchase a tube of silicone and approximately
3 quarts of Automatic Transmission Fluid. Don't forget
to refill your transfer case after you're done! The
rear output bearing housing on the far right is for
that of a YJ. Tom's 231 kit is primarily for Jeep YJs,
but will seamlessly install on a TJ with the addition
of this single component.
is the "short shaft". It is a popular mistake
to think that the "short shaft" name is referring
to the driveshaft, while in actuality, it is referring
to this "mainshaft" our "output shaft"
inside the transfer case, which ultimately allows the
driveshaft to be longer.

Tom Wood professionally prepared for you. Tom's kits have
a core charge, so you send to him your old parts so he
can rework them for new short shaft kits.
bearings were included in the kit to be pressed into
the synchro-hub assembly for additional strength.
is the synchro-hub assembly for a 231 transfer case.
This component is installed securely on the mainshaft
in the transfer case, as the transfer case chain slides
over the teeth on the hub to engage four-wheel drive
- much like the "shift derailleur" on a ten-speed
bicycle... if thats what those things were called.
