Long story short, I picked up a 95 yj this spring, I tried 4HI on the test drive and it seemed to
work. I got it running right and safe enough for the wife to run around town in a few days
but got hurt at work and really have not had a chance to touch it again till today.
So tonight I tried to go to 4LO but cant get it. I got through 4HI and into neutral but cant get lo,
got back into 4HI with some grinding.
Is there a trick? I tried fwd, nut, rev.
Poss. the vacume lines? Linkage?
As you can guess this is my first Jeep
I have had several 4x4's 92 Toyota, 85 Bronco and my 97 Z71 they all have there quirks
but never had this problem.
If it was up to me I'd just park it for now but the wife wants to drive it this winter instead
of the GMC "it's tiny and easy to park" Grrrr

You say you got through 4HI, that sounds like the NP231.
That case shouldn't be used on the road in 4hi.

There are only three cases, which one is yours?


NP231 4L N 4H 2H (only 2H should be used for road driving)
this is a part-time system in both 4wd positions
and driving in 4h or 4l on solid surfaces is bad
for the transfer case.


NP242 4L N 4full 4pt 2wd (2wd and 4full are for road driving)


NP249 4L N 4H (either range can be used on hard surfaces)


To shift into 4lo you can be in park, but it won't shift
if the gears arn't lined up. It helps to be moving forward
slowly (<5mph). Then you just slam the shifter into 4lo.
To go back to 4hi, you just slow down again and slam it back.
(It's easier on the case to do it in park or nutral)

I usually keep rolling, transmission to N, then go to N on the
case and shift hi/low, then put it back in drive.

Go too slow and it will complain loudly.

YJ's only have the 231, unless it's been swapped.

4 high can be shifted into at any legal speed. I use it just like
another shift in the winter. Hit a snowy patch and shift in on the fly,
hit clear road or when I want to turn left at an intersection and shift
out.

It should never be used on dry roads because it locks the front and rear
axles together so when you turn one wheel has to scuff the road. On dry
road, this will bind up the drivetrain and something will break. Our
old roommate blew the transfer case to pieces driving on paved roads in
4 high.

To get to 4 low, you should be just rolling about 1 or 2 mph, then you
bring the shifter to neutral, push it hard to the right and zig zag it
back past the safety stop into 4 low.

You might need some lubrication on the linkage down under too.
