SOURCE: 1998 ford ranger 4x4 Front Axle hubs will not engage

I found a website that explaned that you can remove the hub and dust cover, inside is a spring which holds the hub out, removing this spring and replacing the rubber dust cover and hub will lock your front hubs in continious. as is done on later models, This has worked for my 98 4wd

I have recently had this problem with a customer. It seems the 4x4 low will only engage in neutral with the brake applied. And also check fuse. Then select drive and you will feel it lock in. Don't "goose" the fuel when attempting this.

SOURCE: When in auto hubs the 4 wheel drive doesn't work

They are operated by vacuum. Check to make sure the vacuum lines are connected and not ripped or anything. If that checks out fine, remove the vacuum line from the hub and apply vacuum to the hub, if the hubs lock then the problem is in the vacuum line or switch.

SOURCE: not sure if the hubs are engaging?

Well, the best way is to place the vehicle on a hoist and raise all 4 wheels off the ground and put it in 4WD and see if all the wheels start turning.

Another way is to make a really sharp (slow) turn while the unit is in 4 wheel high or 4 wheel low on dry pavement. You should be able to feel the driveline wrap-up caused by the front wheels trying to grab during the hard turn.

4 Low should be easily distinguishable from 4 High as well as 2 Whl when you accelerate and it feels like the transmision is stuck in low gear and the engine starts screaming for mercy at high RPM and you are only doing 30 MPH.

Can't get my 95 Geo Trackers 4WD to work. The indicator light works still but the wheels themselves won't engage. Can anyone plz help me out with what might be my problem?


For Trackers (and Sidekicks) of this era (1989 to 1998) the front axle locking device is a locking hub on each front wheel. (There are no actuators until the model change in 1999.) Locking hubs come in two flavors, Manual and auto locking hubs. A look at the from wheel should tell you what you have. Manual hubs have a knob like lever with the word "lock" and "free." Auto hubs say "Auto-Locking" right on them. Both types of hubs require servicing periodicity. (Normally annually.) This means removing and disassembling. Then cleaning and light greasing before reassembling. There are some good videos on the web on how to service the manual hubs. Auto hubs are a little harder to ensure they are working properly, but some people like them. (Not me.)

Please note two things:
1. Due to differential action, BOTH hubs need to be locked for any power to be applied to the front wheels.
2. Trackers of this era are PART TIME 4x4, NOT all wheel drive. They have nothing providing for different wheel speeds front to back like a center differential. This means they should NOT be used on non-slippery surfaces like dry pavement. Beside causing handling and braking issues, it can destroy your transfercase driving on dry pavement in 4x4 due to what is called "driveline wind up".

PLEASE if you do not understand this, look it up... if you still do not understand, ask and do not use the 4x4 until you do.

Four wheel drive stays engaged


Is your battery light on the dash on? When my alternator died, my hubs were auto locking due to low voltage in the 4wd selector even though 2wd was selected. The problem corrected itself when I installed a new alternator.

4x4 problems transfercase stays on


If you have locked hub drive in the front end then that shaft will be turning all the time when moving as the front wheels will be making it turn through the diff,. If you have free wheeling hubs that allow you to disengage the hubs then the shaft will be turned from engagement from the transfere case. In that case check that you are in fact changing out of 4 wheel drive and the actuator is not jammed or rusted in the engaged position

How to engage the 4x4


This depends on what system you have installed in your truck. If you have push button 4x4 with auto locking hubs then you would put your vehicle in neutral and press the 4x4 button. You then drive froward about 10 feet and the auto locking hubs should then be engaged.

If you do not have push button control and you have a gear shifter which controls the transfer case you would push the level in 4x4 hi or low depending on what you want (while in neutral) then drive forward about ten feet so the hubs lock. If you have manual locking hubs you need to manually engage the hubs before you put it in 4x4 mode,

I am shocked that the dealer cant fix it, even after warranty. But it sounds like a switch/sensor on the transfer case, or the 4x4 is engaged, and the computer hasnt relayed it to your dash. Can you feel the 4x4 engage? You should be able to.

4x4 malfunctioning


some times the truck has to be put in the opisite direction the for wheel drive was driven in last. so if ya were going forward and you have auto locking hubs then you need to drive irt backwards till lights go out. and if you have driven a long way with it like that then you might have to back up far but it should unlock those hubs. if not then on transfer case there is a small motor that engages and you will need to remove that motor and manually move selector to 2h.

Front hubs wont engage


There are two parts to the auto-locking hubs. Inner and outer. Both of them have small tabs on each of the 'cams'. Chances are, they are broken off on the outer hub. When you clean them up real good, you can see them. I believe when the axles turn the outer hub, the inner and outer cams push against spring pressure and lock the unit to the wheel hub. These hubs will break when engaged at higher speeds, especially on a dry tar road.
