88 Jeep Cherokee 4 Wheel Drive Problem

1988 Jeep Cherokee 4 wheel drive not working. The drive shaft spins so it appears the vacuum actuated lock up isn't working. All vacuum lines are in place. How do we troubleshoot and locate the problem?

Ok so I'm having the same problem. My drive shaft spins but it doesn't really feel like I'm in 4x4 it jumps in 4low when u put it in drive but no matter what, the front tires won't spin, even in mud, they just sit there like I'm in 2 high. It's lifted and the vacuum lines are just hanging on the passenger side, I need an extension kit for them to reach. I'm new to this so Ill ask, do they lines HAVE to be hooked up for 4 wheel drive to work and if so do yall know where I could find an extension?

It sounds like the vacuum acuater is cracked or broken internaly. Recomend replacing the acuater and replacing all vacuum hoses at the same time. There is also a small relay switch under the hood under the radiator tank that may also require replacing.

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.

1997 toyota tacoma will not go into 4 wheel drive


Has the transfer case ever been serviced? The fluid should be changed every 30,000 miles, if not the works can stick and cause engagement problems. Make sure the vacuum to the front hubs is available, if the front hubs are not locking the front drive shaft will turn but no Front wheel lock up and no 4 wheel drive is available.

maby im wrong but if you rev up and only rear wheels spin that means that it might be 4 wheel drive but not constant 4 wheel drive or diff lock system ,,,, ,, in 4 wheel drive all wheells will turn together but if pressure of slip is bad enough or torque high enough only 2 wheels will drive ,,, thats why diff lock locks wheels together in each axle to over come this ,,, all wheel drive like in landrover locks all 4 wheels together to ensure all wheels rotate to give best grip

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

My Cherokee is all wheel drive. I noticed that


Your Jeep is All Wheel Drive and only 4x4 low. The front wheels will spin if needed and/or lacking traction and all the wheels will spin if you do have it in 4x4. It is just a badge thing saying that it is 4x4 but really they are All Wheel Drive

Front wheel will not engage for 4 wheel drive


very possible. Put your jeep on 4 jackstands and put in 4 wheel drive. if the front drive shaft turns pull the vacuum disconnect and check the shift fork. They usually break before the shift actuator.
