Ah. My reading for comprehension skills on public display. Maybe I've
been staring at too much old iron lately.

Hmmmmm not sure really. Hopefully some others will have some ideas.
But, neither of the situations you mention below (smooth dirt road,
8-10 inches of water) would really warrant putting the Jeep in any 4
wheel drive mode I don't think. Then again, I don't think either would
hurt it. But you sure you haven't been binding the transfer case (i.e.
running in 4x4 when there isn't enough tire slippage provided by the
terrain)?

That's possible... I'll admit I'm not totally certain about what
you're talking about (I haven't seen nor worked on that part of my
jeep before), but it sounds like a plausable / reasonable cause of the
problem.

It doesn't seem that it's so much a problem in the transfer case
itself, because when it's engaged in 4HI or 4LO, and it's working, it
works great. It would seem that if it were a problem in the transfer
case, that any 4WD engagement would cause the problem to emerge, and
it wouldn't be so easily remedied.

I'll have them check out those connections, thanks!

True, neither of those situations where the grinding occurred
necessitated 4WD, but some other parts of the trail we were on did.
Besides that, I don't get a chance to use 4WD that often in my
daily-driving routine, so I try to make use of it when I can... if for
no other reason than to keep the parts functioning.

The only time I ever bound the transfer case was about a week after I
bought it, when I was more naive than I am now ;) - one jittery corner
on dry pave was enough to tell me that's a bad idea. Nothing broke
and I've done enough 4WD action to feel assured I did no real damage
to the system.

Do you think that could be even somewhat responsible for this? For as
quick as that bind was, and how well it's worked since then, I have
difficulty accepting that one jittery corner could be the cause of
this other issue... things just don't seem to fit, ya know?

Anyway, thanks for the thoughts! If you have any others, I'd love to
hear them...
