I can't give you a direct answer to your Spicer-18 gear
removal, but in order to remove the "#43 Output Shaft
Gear" (Serv. Manual for Jeep Utility Veh.) you have to
remove the #46 Output Shaft. And to remove the Output
Shaft you'll need to remove sometimes difficult to remove
snap rings. Those gears won't fit through the Spicer-18
bearing holes.
Is your Output Shaft wobbly too? You'll be able to tell
better if you disconnect your drive shaft and shake the
Output Shaft. That's what lead me to my re-build. It
turned out that my bearing$ and gear$ where OK :-) but the
rear bearing adjustment shims were out of adjustment. The
Output Bearing Cup and Bearing weren't holding the Output
Shaft snug enough, thus making things fit loose inside my
transfercase. Since I had everything apart, I replaced
all the old bearings. If you have to remove the
Spicer-18, (for encouragement) it's wasn't too difficult
for me to do - I'm just a shade-tree mechanic. I hope
your gears and output shaft are good - or at least your
spares are. They can be expensive to replace new.

I've posted before on a mysterious noise in my
drive-train. It happens
primarily when rolling to a stop, its inconsistant but
when it happens
its like a low vibration or rumble...like a loose bearing
or a loose
gear on a shaft. To make a long story short, I think
I've found the
source and I need a bit of advice.
The noise seems to be comming from my Spicer-18 transfer
case,
specifically from the "output shaft gear" (I'm getting
all these names
from my repro shop manual, the blow-up picture of the
transfer case).
This gear is *very* wobbly on the "output shaft". After
isolating
the noise to the transfer case and taking the pan off, I
can jiggle
this gear on the shaft a LOT. Putting a little
rotational preasure
on this gear, the teeth that mesh into the larger
intermediate gear
actually slide backwards and forwards almost 1/8 of an
inch. I took
the pan off of another transfer case I've got just to
compare, and
it isn't near as wobbly as the one in the Jeep...so I've
got a high
confidence level that this is indeed my problem.
My question is, can the "output shaft gear" and perhaps
the "output
shaft" itself be replaced without removing the whole
transfer case?
The intermediate shaft was replaced about 1000 miles ago,
and I believe
it to be in good shape. Everything else up there looks
to be OK,
just this one wobbly gear so I hate to take the whole
thing down.
Any advice is appreciated, TATIA (Thanks A Ton In
Advance).
