Yes you can
It doesn't, if there is no one around to interpret the vibrations caused by the tree into sound, they are just vibrations, not sounds.

But you can still drive without a front driveshaft.

It does.

Sound is a physical movement, you don't have to hear it for it to exist...

Of course it makes a sound. The fact that no one is there to hear it, doesn't mean the sound wasn't produced, just that it wasn't heard...even a blind man can feel the heat of the sun...

Why are people arguing on a dead thread brought back by a smiley?

EDIT: Even if it is about trees (now that I read closer)

Until, I dunno, you start puking atf out of the rear output on a stock slip-yoke 231. But what do I know...apparently I'm not knowledgeable at all about how a transfer case works.

Here is a picture of a 231, now tell us where this leak is gonna come from? Are you thinking the 231 is like a 2wd automatic tranny where the slip yoke actually goes into the tail housing of the tranny?

From between the splined output shaft visible in that image and the seal meant to hug the outer spline shaft that's missing. Behind that harmonic dampener (which I don't have, btw) is the seal and bearing. The seal has a gap between its inner diameter and the output shaft, meant to be taken up by the internally splined tube attached to the ujoint yoke on the driveshaft itself. Illustrated in the pictures in this thread:

http://www.jeepforum.com/forum/f37/n...eak-fix-82091/

It's a different tailshaft housing, but the idea is still the same. What you see there isn't completely sealed. Prove me wrong. It's entirely possible. But I don't think so. It's entirely possible that the design changed to remove that tailshaft and place the seal directly into the speedo sensor housing seen behind the harmonic dampener, and that's what I learned way back in the day. The old style cases WILL leak oil through the bearing and those splines. Quite possible that it won't leak from the newer style. Meh.

Wait for it, keep in mind that TJ NP231's don't leak fluid when the slip yoke is removed...

Ok,
look at fig 3, where is the seal? Is the accordion boot the seal?
Fig 5 shows the seal.

The problem is that we are talking about the TJ transfer case and not the one you learned about "back in the day". There was a time when just about every time an airplane landed the mechanic would need to replace at least one of the cylinders. When was the last time you saw that happening on the plane sitting at the gate waiting to board passengers?

"Back in the day" makes for fond memories that too often don't apply to today.
