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

Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
Sometimes shifting out of 4H with an automatic, it might take a few seconds
for the 'case to disengage because of the more constant torque load of the
automatic; shifting the tranny into "N" will help reduce this time. This was
the case with our '93 GC, '94 XJ and my wife's current TJL. That said, 15
minutes as the OP wrote is definitely too long for the 'case to disengage.

Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
Jim, your '88 and my '89 Cherokee had the exact same transfer case and
as the owners manual instructs, I NEVER had to do anything unusual like
you suggest to get it to shift back into 2Hi beyond moving the t-case
lever back to 2wd. Your advice saying he should shift into neutral
before shifting back into 2wd is just plain 'wrong' and ill-advised. It
is absolutely not necessary, the most that is ever needed to help
accelerate the shift back into 2wd is to simply let off on the gas a bit.

as the owners manual instructs, I NEVER had to do anything unusual like
you suggest to get it to shift back into 2Hi beyond moving the t-case
lever back to 2wd. Your advice saying he should shift into neutral
before shifting back into 2wd is just plain 'wrong' and ill-advised. It
is absolutely not necessary, the most that is ever needed to help
accelerate the shift back into 2wd is to simply let off on the gas a bit.

Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
Matt, my Cherokee was an automatic and the most I ever had to do to
hasten the shift back into 2wd was to let off on the gas. That raised
the level of engine vacuum which helped speed up the shift back into
2wd. If things are operating correctly, there is never a need to shift
into neutral to get it to complete the shift back into 2wd. The
transfer case is a shift-on-the-fly, not
"shift-into-neutral-then-shift-into-2wd.' :)

Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
Matt, my Cherokee was an automatic and the most I ever had to do to
hasten the shift back into 2wd was to let off on the gas. That raised
the level of engine vacuum which helped speed up the shift back into
2wd. If things are operating correctly, there is never a need to shift
into neutral to get it to complete the shift back into 2wd. The
transfer case is a shift-on-the-fly, not
"shift-into-neutral-then-shift-into-2wd.' :)

hasten the shift back into 2wd was to let off on the gas. That raised
the level of engine vacuum which helped speed up the shift back into
2wd. If things are operating correctly, there is never a need to shift
into neutral to get it to complete the shift back into 2wd. The
transfer case is a shift-on-the-fly, not
"shift-into-neutral-then-shift-into-2wd.' :)
