Re: Clunk after switching from 4hi
 

If you must use 4WD, then shift out of it earlier, and use as little gas as
possible.

Your tcase is a chain-driven unit, and when you shift out of 4WD, it takes a
while for the gears and such to actually disengage, this is why it takes so
long for the clunk to come.

The tcase has no differential capabilities, so the different speeds of the
front and rear tires will quickly bind it up to the point that it will not
disengage. The length of time it takes to disengage is a sign of how much
damage has been done to it, when it is new it should disengage pretty
quickly, but as the chain stretches, the time to disengage will become
longer and longer.

If you are seeing "normal" cars and trucks getting around town, then you
should be able to get around town in 2WD too. If you need 4WD to get going,
and you are driving the same as you do in summer, then you are binding the
tcase and stretching the chain.

Re: Clunk after switching from 4hi
 

It normally disengages almost instantly. The two times it hasn't was when I
came from a stop sign (slick/slushy/snowy) and TURNED onto a road that
quickly turned to dry surface that this happened. Guess I'll stop doing
that....

I've used it since, and as long as I am not turning onto something paved, it
works just fine (i.e. disengages just about instantly).

It's the turning that binds the tcase. As I explained earlier, the tcase has
no differential-qualities that prevent stresses from building up, and the
front and rear travel different distances, which is what causes the stresses
to build up.

I live in sunny Southern California, and have never had to grapple with the
problems brought on by snow and ice, but if I took my Jeep up to the snow, I
think my strategy would be to engage 4WD when it was needed, not engage it
in the hopes of not needing it. Having said that, I have lockers front and
rear, and I have a complete other set of issues relative to my lockers to
worry about when driving on icy roads.

Re: Clunk after switching from 4hi
 

Eric:

It's the turn on dry pavement that is the problem. The drivetrain will bind
up almost instantly during a turn. The sharper the turn, the quicker and
harder the drivetrain will bind up. Turns on dry pavement while in 4WD are a
definite NO NO.
