    If you need a diagram I don't have one but if you have a question about a line or two, I can likely tell you where they go.

I do not have a vacuum diagram for the 89 Cherokee, but my 89 had the same issue several times and all it was is that the block of vacuum lines that go into the front axle on the rear of the axle on the passenger side of the vehicle. I ended up having to put a zip tie around the axle and hose block to hold it on. Have not had the issue again since doing this. Hope that helps.

    I was able to locate a Chilton and Haynes, but both of them just have the same vacuum diagram that is on AutoZone's Website: http://www.autozone.com/shopping/repairG...
    That diagram does not look like it will be much help in this case.

    I probably won't get a chance to get under my Cherokee until sometime next week.

Is there an electric or vacuum switch on a 2001 chevy blazer


There are 2 models here the push button will flash if the system is not engaging or disengaging properly . If front drive shaft is turning. That is with car raised and supported . if front drive axles do not turn then the axle actuator is not engaging axle shaft passenger side. Remove actuator and manually engage shifting collar with a screwdriver still does not turn then inner axle is twisted.

08 f150 4x4 on front end only one side is disengaging when in 2 wheel drive. The problem is when engaged into 4x4 wheel drive the front drive line spins and both sides engage but only the back wheels spin...


If I read this correctly ( which I might not have, bit early for me ), the front drive shaft will engage ( from the transfer case ) but the front wheels are not engaged ?

If so, sounds like either the vacuum from the IWE ( Integrated Wheel End ) is not being released, or the IWEs have had an issue with part vacuum ( damage vacuum lines ) and the IWE gear is rounded off.

If you pull the vacuum lines at the IWEs ( there are 2 lines, 1 is the vacuum line, the other is the vent tube that routes up into the engine compartment and is not attached to anything ), the front wheel should engage ( might need a 5 * turn to mesh the gears ). With the vacuum lines off, jack up the front axle ( take precautions, chock the rear wheels, parking brake, jack stands, etc ) see if the front wheels are engaged ( turning one wheel should turn the other ). The option is to do this after the truck has sat over night, and the vacuum has been released out of the vacuum reservoir.

If the wheels turn correctly ( engaged ) I would think the contact plates in the transfer case are not making contact. Good starting point for this is the connector on the side of the transfer case, some times this gets gummed up, and the pins do not make good contact. The contact plates in the transfer case are used for a few things, one of them is to signal the IWE solenoids to release vacuum to the IWEs.

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vacuum is removed the spring engages the IWE.

4 wheel drive system not operating, have already repaced drive motor on transfer case, still not working


Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Engine on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

IF the front dive shaft does not turn, check that the vacuum shift motor on the front axle is operating.


Item #10 in the diagram below.

The vacuum shift motor is vacuum operated ( name says that, I know ) the pink vacuum line is 2WD operation, the Light Blue vacuum line is 4WD operation.
If the motor does not move, you can check the vacuum lines to the vacuum solenoids on the firewall

The other is the vacuum reservoir behind the battery

Right side will not go into four wheel drive. I have the manual shift in the floor. Left side engages--right won't.


Sounds like an issue with the IWE gear ( spring ) not engaging.

The IWE ( Integrated Wheel End ) is vacuum & spring operated. When the truck is running and in 2WD, vacuum is applied to the IWE, and holds the IWE gear out. Once vacuum is removed ( placed into 4H or 4L or turn off ) the vacuum is removed, and the spring pushes the IWE gear into place, locking the wheel to the front axle.

Could be a plugged vent line, you can start by removing the vacuum line from that side, and the vent line ( same vacuum line, just routes into the engine compartment, and is not connected to anything ) and see if the IWE will engage.
If the spring seems to move, but the wheel is not engaged, you would need to take it apart to confirm if the IWE spring or the gear itself ( worn down from part engagement ) is the issue.

This is a block diagram of the IWE system

There was a TSB on the IWE solenoid, where water could get into the system, and cause the IWE gear to be part engaged, causing the gears to be ground down ( you would have heard a grinding noise in 2WD ).
This is the TSB

My 1991 jeep cherokee will not engage all four tires when its put into 4wheel drive. the T-case engages but for some reason only the 2 back tires spin. is there a vacum line that may be cracked?


could be, there are lines that run to frt diff, theres a vacuum reservoir that stores vacuum that comes from engine then theres aline tovacuum control switch then to vacuum swith to light the 4wd light and a line to shift motor that engauges the front wheels, check all these line and you might find a bad leaking line hope this helps.

89 jeep cherokee 4 wheel drive won't engage gears arn't meshing and no indicator light


If you engage the 4WD with a switch instead of manually, there is a motor in or on the transfer case. Because of the location, these can go bad. u need to check all your switches and actuators there are actuators under vehicle that clog up with dirt.also try putting vehicle in neutral before engaging 4x4.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

2005 ford f-150...4 wheel drive will not


Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vac is removed the spring engages the IWE.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

- If the front drive shaft does not turn :
Shut of the truck ( still jacked up, and supported ) remove the vac lines from the IWE. The spring should push the gears in, without the vac line on.
Check the vent line ( tube that is routed into the engine compartment with nothing attached to it ), for blockages.
If the vent line is clear, and with the vac lines off the IWE should be engaged ( both front wheels locked ).
If they lock, the problem is with the IWE solenoid not shutting off vacuum to the IWEs. There is a TSB on the 2004-2006 IWE solenoids, a newer revision has been made, and used from 2007 and newer MYs.

Four wheel drive wont engage


Hi ninja,

Select-Trac?

Make sure you have plenty of 90 wt. in the front axle. I've got an '86 Cherokee Laredo. It doesn't kick right in to gear. You need to be moving, but not to fast. Sometimes reversing, then back into drive works.

When you disengage it, if you are moving at or above 30 mph, you'll hjear a rapid clicking from the front axle as it tries to let go. Put it in neutral for a second or two. That will take enough strain off the drive train to allow it to disengage.

Best regards
Mike

Had service 4 wheel drive light now their is clicking noise from the dash we think relay but what one on tran or inside dash


Hi Steward,

It's unlikely a relay is producing your symptoms.

The on the fly 4WD in the Cherokee is engaged inside the front axle. If for some reason it doesn't fully engage, it produces a clicking sound until it either fully engages or disengages.

If that clicking you are hearing gets more rapid as you increase speed, slows down when you do, then that's what it is.

A vacuum leak is the likely problem, easy to fix, difficult to find.
I have a Cherokee. I had the same problem. Start checking vacuum lines that lead under the engine to an actuator attached to the front axle.

Good luck,
Mike
