Walt & Lynda Johnson

I've had exactly the same problem with my 1986 Cherokee. What is
happening is that the vacuum motor on the axle isn't disengaging
the axles from the differential. Simply replace the vacuum motor
with a new one and the problem will go away.

On the Cherokee, instead of freewheeling hubs, the right hand side
axle is split with two splined sections. Normal 2WD operation the
spline joiner is slid on to one axle section. The spider gears
in the differential rotate in opposite directions and the
differential center section is stationary. When placed in 4WD, the
spline joiner slides to connect the two splined axle sections thereby
locking up the axle. There are three hoses, one to engage the
axle via the vacuum motor, the second to disengage the axle via the
vacuum motor, and the third to send the "I'm locked up" message
to the light on the dashboard.

If you have ever had the tc apart you can see where the pop comes
from. The movement of the coupler into the gear that drives the chain
is pretty small and it doesn't take much slippage to leave the teeth
just barely engaged. No biggy if the vacuum pulls the front axle
apart but if it doesn't that gear makes one heck of a noise as it pops
out of the synchro setup. I'm not sure what's sticking in ours, but
both of us have checked and found the axle free, front drive shaft
free and that stupid light glaring at us. I think that's what going
back into 4HI and backing off the gas to increase vacuum does - just
cycles the switch so that it finally breaks contact. If you can move
the shift handle all the way, the linkage is adjusted right and tight,
then the tc WILL be disengaged. That light can be a real nuisance.

4LO to 4HI is a whole different ball game, Earle. That's one where
neutral and barely rolling (4HI to 4LO) or neutral and stopped (4LO to
4HI) is pretty much necessary. There is nothing even close to a
syncro on the dog ring that locks/unlocks the planetary gears to
select low range - that damned thing will grind even if you are
parked, I swear. 4HI to 2HI and back has a synchro that helps out
some and if you have the newer model front axle that runs locked all
the chain drive gears are always spinng at very near the same speed as
the input drive anyway. Plus, there is a neutral between 4HI and 4LO
where there is no disengaed point in the 4HI to 2HI shift to allow a
speed mismatch.

If you have to go to N, there's something wrong. From 2hi to 4hi and
back should work just fine at "any legal speed". My first XJ (Command
Track) did this with no problems whatsoever. The second (Select Track)
seems to take its time if cold or if the tire inflation is off front to
rear, but works just dandy when warm with proper inflation.

Lifting up on the gas helps, but having uneven tire pressure can cause
problems. Once, when I didn't realize I had a low rear tire, the only
thing that worked was stopping and reversing for a few feet.

All of this concerns only the dash light and I suppose the front axel.
The shifter clearly (you can tell by the feel of the vehicle) gets you
in or out of 4X4.

Both Cherokees were 4.0 automatic tranny. First was a 92, second is a 91.

Never a need to go to N. 4Lo is a different story.

Best Regards,

DAve
