Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
 
I felt the same way, and our Cherokee was practically new when this
happened, nothing apparently wrong with it. I also figured out that
anything that used that much fuel, should be able to hold a 4x8 sheet of
sheetrock, or 20 of them if need be. I replaced it with a 3/4 ton Suburban,
and I have been happy since. It has practically the same transfer case, a
similar transmission, and doesn't give any grief shifting the transfer case.
Maybe the Cherokee was broken, or maybe the Aisin transmission is just a
piece of crap. I didn't feel like finding out.

Re: 97 Jeep Cherokee 4wd - 4wd Won't disengage
 
No, but both will relieve the torque load.

Shifting the transmission into N for shifting into or out of 4lo helps a lot
to, but that's irrelevent to the OP's issue.

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

What an interesting exchange. I have a 94 Cherokee, LTD SE 4.0 Auto, which I
recently bought. Same problem with shifting in and out of 4 wheel part-time
and 4 wheel full time. Often sticks in 4W part time. Only way to get out to
2W is either stoop and reverse a little or wait ages.

Always seem worse when everything is cold.

Anyway, greetings from England/
..

94 Jeep Cherokee - part time 4wd Won't disengage
 
The OPs address going from 2w to 4wd and back. My new-to-me 94 Cherokee has
only 4H-N-4L positions. This is my first 4WD of that type. When making sharper
corners, like when parking, it "crabs" like my previous 4WD vehicles would do if
I had forgotten to take them out of 4WD. This can't be too good for the
U-joints or other componants. Is this normal or do I need to fix something and
if the latter, what?? TIA, Vito.
