Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
 

I have always shifted on the fly and this problem has only reared its
head over the last six months. And I hit several lights on the way to
work so the jeep is constantly on and off as far as gas goes/tension on
the drive train. I just don't know the inner workings of the transfer
cases. Am I sliding some type of clutch plate mechanism together or am
I sliding a gear into place that engages the driveshaft to the front
differential directly? Can this be caused by low fluid perhaps is it
just showing its age. I have 120,000 miles on it and I would like to
put another 40+ on it before any major repairs are needed. Not having
the car payment has put two four wheelers and a motorcycle in my
garage.

Depends on what you are using to determine when it shifts. I've got
an 88 4-spd, son has a 91 auto. On both, the 4WD light is basically
an idiot light - if it's on you MAY be in 4WD, especially shifting
back to 2WD. Looking at the actual state of the system (like you, we
both have the front axle diconnect on the axle), we usually find that
both the tc and the axle are disconnected and the light is still on.
I have no idea where one would adjust the switch, but it is not a
positive indication od the state. The transfer case - which is the
important part - will follow the shift handle but it may take a while
for the axle to disengage even though the load is fairly light. As
long as you get the gears disengaged in the tc there is no problem
with the front axle being engaged since there is no way for it to bind
up with the tc properly shifted. You might want to check adjustment
of the transfer case shift rod. Could be that it has shifted and not
quite getting back to 2WD when you shift now. There is just one small
bolt that locks the shift rod in place by friction and it WILL slip
over time.

For both the XJ and the MJ, we can usually get the light to go off
(it's a nuisance if it just stays on) by shifting back to 4WD then
immediately into 2WD while letting up on the gas to get a higher
vacuum.

I had this problem a while back with my '98 XJ... it would not engage
4WDH unless I first went into neutral then back into 4WDH. After the
shift linkage (or rod) was adjusted the problem went away.

On our 88 we have to bump the vacuum with a fast decel to make it shift
quick, otherwise it takes time. That is just age on leaky vacuum
fittings, usually the front axle one and doesn't apply to the new ones.
