The front hubs are activated with vacuum. You have a vacuum leak or bad chech valve in the line. Check the lines that are near the firewall and see if they are ok.

SOURCE: 4 wheel drive selector won't move to select 4x4

I am guessing the way you wrote this that the switch moves but 4H is not activating. If this is the case, then check the fuses/breakers as described in your fuse/relay section of the manual. If these are good, then check the connections to the 4x4 motor on the txfer case. Sometimes the connection there gets corroded or damaged while 4wheeling.

Also, the vacuum operated ft wheels must have good vacuum to the front diff (you will see the vac line on the right side of the diff AS WELL AS the two vacuum switches on the passenger side, firewall under the hood. The fuses/relays/breakers are first to check. Then check the vacuum lines under the hood to the TWO electronically activated vacuum switches on the firewall. Lastly, check the vacuum line to the differential and the connection to the actual transfer case actuation motor..

SOURCE: Truck has a noise vibration when hubs are locked

Could be a few different things. I really doubt the carrier is bad on the truck. I would be looking at the axle half shaft u joints on both sides, and or the cv and u joints on the drive shaft to the front differential. If one of these u joints are bad it can make all kinds of noise and cause vibrations. Especially when under a load. Good luck.

Has the car even been in an accident? If so it could be a bent frame (worse case), Otherwise the car could be off balance and needing an alignment (Most likely - best case) :)

Can i manualy take it out of 4x4


Those older fords you have to put the 4x4 selector into 2H or 2 High on the floor shifter. Then go to the front tires and in the very center of the tire there will be a knob that say Locked and Unlocked. Turn the knob to unlocked on both sides. Then you will not have front wheel dragging on the drive train and only the rear wheels will be the drive tire. TO put it back in 4x4. Turn the knob back to locked on each front tire and put the truck in 4H or 4 High to get 4x4. Only use 4L or 4Low when your stuck to prevent spinning your tires with full power.


Now if your has the automatic locking hubs I would switch them out with manual ones because the automatic ones were problematic where they get stuck or not work at all. It requires replacing the locking hub assembly which isn't that hard to do.

I have a 1993 ford f150 4x4 i cant get it out of 4 wheel drive it still drive in 4wd how do i fix this problem


if it has automatic lock in hubs only!! start truck, put truck in neutral, push button for 2x2 shift into reverse,back up 5to 10 feet,truck should shift back into 2x2 automatically. shift into drive and the 4x4 light should go off. if you have manual lock hubs you''ll need to unlock those manually on the 2 front wheels.w/truck in neutral and emergency brake on or someone holdling brake inside truck,go to front and rotate the locking hubs to front tire or wheels in centerof hub to free wheel.they will be marked,or should be. if not,then try turning the center of hub switch counter clockwise until it stops turning,then go to passenger side and turn it counter clockwise. thank you for choosing fixya.

How to engage 4x4 in a 94 ford exploer (auto trans) mauale hubs


Before you start the vehicle lock the hubs in by turning the lock out device in the hub center of each front hub. Now you can start the vehicle and while in park or neutral move the range selector on the floor to the range you would like to use. Most often you will use the 4 wheel high setting. The low setting is only for extremely heavy pulling and will throw you across the seat if you accelerate too hard. Never exceed 45 miles per hour when in 4 wheel drive as you will burn out the transmission or 4X4 transfercase bearings. Now to go back to two wheel drive. Move the floor selecter back to 2 wheel drive setting. Do this with the vehicle in park or neutral to prevent damage to the vehicle. Now you can unlock the hubs by reversing the hub lock out device in the center of the two front hubs. Important little known fact is that you do not want to drive aroind with the hubs constantly locked in as you will lower your fuel mileage and cause extra wear to the axles and associated parts. Hope that helps, please come see us again if you have any more questions, Thanks, Rich.

1984ford f150 Ido not know how to put the truck into 4wheel drive


There should be a lever shifter on the floor board with 2h- 4h-4L on the knob. Pull or push the lever to 4H then get out and go to the front axle. In the middle of the front tires there should be a locking front hub assembly, turn the selector to lock, do this on both wheels, your truck should now be in 4 wheel drive. To put it in 4L you need to havt the transmission in nuetral before you shift the lever. Once done playing make sure you unlock your front axel(hubs) and place the lever in 2H.

My 4 wheel drive will not disengage


You might want to check the gear selector switch that is located on the driver side of the tranny, if the 4x4 is electric and not manual for engagement, selector must read neutral to disengage 4 wheel drive. by experience if you drove it through deep water gear selector switch can get damaged.
Your hubs may be locked as well. Try reversing for 30 or more feet to try manually unlocking your hubs. Make sure 4WD is turned off when trying.
