Four wheel driving not working properly

Good evening,

This could be the actuator motor on the transfer case but needs to be confirmed.

I attached a diagram and some other information for you. You need to test for voltage to the motor when commanding 2 or 4 wheel drive.

Removal

WARNING: The electrical power supply to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning of the air suspension switch located in the rear jack storage area. Failure to do so can result in unexpected inflation or deflation of the air springs which can result in shifting of the vehicle during these operations.

1. Raise and support the vehicle.

1. NOTE: Make sure the motor mounting surfaces are clean.

Apply a 3 mm (1/8 inch) bead of sealant to the motor mounting surface on the case.
Use Black Non-Acid Cure Silicone Rubber E7TZ-19562-A or equivalent meeting Ford specification ES L-M4G273-A.

Thank you very much for your help.

You are welcome.

Always glad to help.

Drive Train Axles Bearings problem
1999 Ford Explorer 6 cyl Four Wheel Drive Automatic

My 4 wheel drive is not working. The transfer case motor is working for drive range but front wheels are not turning. Eletrical wires seem to be in good shape. How do i make the front wheels turn? I desperatly need the 4 wheel drive to work.

Are you sure the actuator on the transfer case is working? That is the most common problem with these vehicles.

Let me know.
Joe

Not for certain. When turning the knob on dash while in nuetral you can here the transfer case changing gears from 4 high to 4 low. The trans. acts to be in 4 low but the front driveshaft still isnt pulling front wheels. In the snow the rear wheels turn but front driveshaft never turns. So the actuatur seems to be putting the the transfer case into low gear otherwise the transmission wouldnt act any different. I can hear the motor turn and gears sound to be interlocking? Are they ? Could the actuator not be working and still sound as its working ?

4wheel not working replased shift motor had no luck lights on dash working took shift motor off tride shifting manualy still does not work hope i doent need tc

Are you getting power to the 4wd actuator? If so and it still doesn't shift, check the vacuum hoses going to the front differential.

Let me know what you find.

Joe

On my Explorer, the dash lights for the 4X4 High & 4X4 Low are flashing at the same time. In testing the 4 wheel drive, the system is not working. One person told me it could be the fuse. In checking those, all are good. The ones to the left of the dash beside the door & the ones under the hood, driver side. My next thought was, could it be the relay? Which one is it? & how do I test it? The 4 wheel drive does not get used very often, except in winter and the vehicle is in great shape. Any help would be appreciated. Thanks

The relay is in the power distribution box under the hood. The cover on the box identifies what each thing is. What to do is locate the relay and switch it with one with the same part number. Let me know what you find with that. Also, if that does nothing, check to see if there is power to the actuator on the transfer case.

Let me know.

four wheel drive will not engage

When you switch to 4wd, can you hear the actuator working on the transfer case?

i here no sound at all

So my four wheel drive auto will not engage the light lights up in the dash and you can hear the vacuum solenoids clicking up front by the right headlight. Put the SUV in "N" and hear nothing in four wheel drive auto but I can hear it engage in four wheel drive low. Not sure what the problem is any help would be great.

check the shift relay and see if motor gets power through both ways then scan for codes auto parts can for free if a code get back to us. It can also be the GEM module bad for that as well. See picture on location and what wires to check on motor on t-case.

I HAVE THE EXPLORER I LIVE IN C.T. AND IT IS VERY COLD. The four wheel drive is not engaging when i turn the knob to 4x4 only the lights come on in the dash board why isnt it engaging?

hi ben the front axles are most likely not engageing. remove the small motor on the axle dissassemble and clean. also one on transfer case.. good luck billymac

i have a 95 explorer, the 4x4 lights r flahing and my 4x4 doesnt work.i checked the fuse its good. i also tried changing the shiftmotor no luck. can u help me im stuck ,and dont want to take it to a dealer they charge too much?

You need to have the code(s) read, auto zone does it free, write them down and post here. All tires are the same EXACT size?

I agree with his recommendation. However, have you ever checked to see if you are getting power to the 4wd actuator from the switch?

I have a 1998 Ford Explorer with on demand 4WD. I have had the vehicle looked at by Ford repair shops as well as independent shops and have had numerous fixes applied costing me lots of money but the problem remains unresolved. When starting down a mountain road right after turning the car on I engage the 4WD low in 1. The vehicle starts to walk down the road but only gets 1/4 mile down before the 4WD lets go and I find myself freewheeling down the road. I have to apply brakes from that point on.
All the shops engage the 4WD on flat surface or on a lift and see the four wheels turning and tell me they have fixed the problem. Since there are no significant hills where I live I cannot demonstrate the failure to them. Any ideas on what to point them to so they can fix this right

is it electronic or manual 4WD?

It is electronic. There is a switch on the console that allows you to go from 2WD to 4WD high and 4WD low. There is a transfer case motor that engages when you move the knob to 4WD.

Hummm I suspect it is the motor lock solonoid that keeps the transer case in 4 wheel drive. Downhill you are pulling against the reverse torgue of the grade causing pressure on the motor. It releases when it gets hot and causes the problem.

When it resease does the 4WD light go out or stay on. That is the biggest clue. Let me know.

Thanks for getting back to me. I believe that even when the 4WD cuts loose the 4WD Lo light stays on. Is that helpful? What do I tell the mechanic to look for since they all believe "there is nothing wrong with your 4WD" I believe your explanation makes a whole lot more sense. Look forward to your answer

If I owned the vehicle, I would go to a salvage yard and buy the 4WD drive motor and solonoid and replace it. It is not a hard job, just dirty.

The light on indictes it is not a control failure but a hardware failure. That eliminates the computer, switches and wirng to the assembly.

Remember, I am not there, just an old mechanic who owned a shop for 40 years that did only automotive electronics which included problems like yours.

When everyone gave up on a problem, they brought it to Lee's Auto Clinic. Good luck

Thanks for taking the time to read over my car problem. I can tell you that what you've said makes a lot of sense compared to the other advice/troubleshooting I got from the different shops. A Ford dealership put in a new transcase motor a few years ago and I suspect the work was very shoddy. The reason they did it was because the console light was flashing between normal, 4WD Hi, and 4WD lo while we were driving on the highway. Hopefully I can find a shop who can do the work.
