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.
Sounds like the bearings need to be replaced Merl<grin>. I'm only grinning
because the answer to your second question is Nope!!.
Pull it down buddy and do the job "proper" (as they say in the classics).
Now, if you have done the bearings you may need to Vernier the bearing
hole in the case to see if its allowing the cone to move too much. I hope
it's not that mate.
Does this help?
All the best,
Ben.
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).
