    if the 4 wheel drivestill work do you think the loud bang caused any damage elsewhere?

  • Bill Lindsey Jan 03, 2013

    Not likley if this is the first time you've had this issue but your truck is 13 years old. Maybe it's time you start putting it in fwd before you get to your driveway. Also if you have manual locking hubs, it should'nt hurt to leave them locked and ingage and disengage through your transfer case as long as your just running around town. PS I'd like to know if that works out for you. I used to leave the hubs locked all winter long in a toyota truck i had and it didn't hurt anything

  • Patrick Martin Jan 03, 2013

    yea typically i leave the hubs engaged about twice a month for short distance non highway driving as i heard that can help the life of them. i have never had a 4x4 problem with my truck until i heard this bang and man was it loud. i assumed it was bc i gave it a bit too much gas without allowing it to roll at all and engage while already being at a steep angle in the snow/ice. i also have 37 bfg mud terrains and a 5 inch lift and am due for ball joints. i just hope i didnt do any damage and dont need driveshaft ujoints or center bearing

  • Bill Lindsey Jan 04, 2013

    your probably right about your truck not being all the way ingaged when you accelerated.

  • Bill Lindsey Jan 04, 2013

    I did the same thing in my silverado several years ago and haven't had any trouble after that

  • Patrick Martin Jan 04, 2013

    yea no problems with 4x4 or noises in or out of 4x4 all day. i am worried about a clicking sound i hear in my rear end typically from a stop to a go and hitting bumps at angles like into a driveway. center bearing? thats what i think atleast

  • Bill Lindsey Jan 04, 2013

    Check the center caps on your wheels. If thats what it is you can bend the flange slightly. If they are plastic 2 or 3 thin coats of RTV gasket maker (not adhesive) should stop that noise

Could be one of your hubs wasn't fully locked or maybe your transfer case wasn't fully ingaged

Posted on Jan 03, 2013

Testimonial: "i was unsure if i had to slowly roll to fully engage but may haven given it to much gas. it was in park i got out and locked the hubs hopped in put in 4 high then immediatly gassed it and kaboom. im worried if i did any damage. i have never had a problem with my 4x4 but i usuall engage at bottom of driveway and slow roll"

SOURCE: warn manual hub install 2000 f-250

When you turn the knob to 4x4 the transfer case will engage then it will also activate the vacuum for the hubs. the truck will kick to a lower gear with transfer case engaged but the hubs are not. thats where the manual hubs come in you will have to lock them in order to spin the wheel.

SOURCE: automatic 4x4 locking hubs one side not locking in

There is a possibility the axel U-joint is binding, this will put side load on the hubs and keep them from working properly. Turn the steering wheel either far right or left and with front of truck off the ground or the front end disengaged, see if the axel shafts turn free, both sides. If there is binding the U-joint(s) will have to be replaced.

I just purchased a 2003 f 250 ford 4x4. i need to know how to operate it in four wheel drive. the truck has manual hub knob on each front wheel. do i turn these to "lock" then put it in 4x4 hi?

Yes, that's how you do it.

Me, I lock 'em before it snows the first time and unlock 'em after the last snow. If I think I might spin I get out and lock them before I drive into something sloppy. It's a lot of fun watching a guy with his arm up to the elbow in mud trying to lock his hubs..

Manual locking hubs seem like a pain at first, but when you're pulling someone out of a big ol' snowdrift because their fancy hubs are broke again you'll realize that how your truck is is how it should be.

How do i use four wheel drive in the snow

Put the transmission shifter in neutral, shift the transfer case into 4 wheel high, for regular road speeds, you need to know if you have manual or automatic locking hubs, if they are manual go to each front tire and turn the switch on the hubs to the lock position, put the transmission shifter in gear and go. Be careful and don't drive like you're invincible. JKust because you have a 4x4 vehicle does not mean you will not loose control.

I have never driver a 4 wheel drive. I am going from portland oregon to phoenix az. not sure how or when to switch to four wheel. does the truck need to be in park? etc.

Do you have manual locking hubs on the front? If you do, you have to turn them to 'lock' position. If you have automatic hubs, you skip that step. Never shift into 4x4 low range while moving. You must come to a complete stop to shift in or out of low range. Regular 4x4 (high range) can be engaged while you are moving. Let off the gas, and put it in 4x4 high range, do the same to go back to 2 wheel drive. Vehicles that are part time 4x4 (can be shifted in and out of 4x4) should never be driven in 4x4 while on a dry surface, as you can cause excessive wear or even failure of the system. So only use it in snow, off road, etc. Have a safe trip!

My friend has jus bought a 1992 Pajero, 2.5 auto, swb, no manual with it. He has heard that when changing from 4x4 to 2wd that you need to stop the vehicle, go intp 2wd, then reverse for a couple of yards...

He need not stop to change from 4x4 hi to 2wd. He can also go from 2wd to 4x4 hi "on the fly" as long as the front hubs are locked, he is going straight and maintaining a steady speed. If the hubs are manually locking, he must exit the vehicle and lock the hubs. If they are automatic locking, in order to go from 2wd to 4x4 he must stop, put the vehicle in 4wd hi and pull off. Once he starts moving, the hubs will automatically lock, he can then switch from 2wd to 4wd hi and vice versa "on the fly". To unlock the hubs, he will need to stop, put the vehicle in 2wd and back up 3 ft. (remember, this is on automatic locking hub models). Hope this is helpful!

95 dodge 2500 4x4 front axle clicks in 2wd not 4wd when engaged

Do you have automatic locking hubs? Do you need to turn hubs on wheels in order to have 4 wheel drive work? If all you do to get in 4wd is move shifter, then you have automatic locking hubs. The clicking indicates that the hubs are not fully disingaging. To check, block rear wheels, jack front up, and turn tire. the axle should not be turning...if it is, hub is still ingaged....time for new hubs.....if hubs are bad, and you want to save money, you can purchase a set of manual hubs made by (WARN)...its more than half the cost, but you will have to turn hubs to lock and unlock manually. still need to use the gear selector to put and take out 4wd.

Was driving onto a paved access road to beach. put switch in 4 hi about 40 yards from sand , increased speed to about 10 mph heard a sudden bang in front of truck. Truck came out of 4 wheel. 4 wheel lights...

Your automatic locking hubs are broken. Very common on ford trucks. The front hubs are geared with hard nylon gears, and are easily broken. If you replace your front hubs with "warn (name brand)" manual locking hubs, your issue will be resolved, and you won't have that issue again on your truck.

If you replace the hubs with manual locking hubs, you will have to stop, get out of the truck, and manually lock in your hubs every time you want to engage your 4 wheel drive. It beats getting stranded somewhere with no 4x4 at all; like you have now.

If you replace your hubs with the factory automatic locking hubs, the issue will return again in time.

I have a 1999 Expedition. We had a snow storm I've had to put it in 4WD on occassion. Now that all the snow is gone, I put the switch back in AWD. the 4x4 light goes off, but its still in 4WD. any...

it sounds like your front automatic locking hubs are stuck locked try putting it back in four backing up a little bit put it in neutral and take it off 4wd and back up again if this doesnt work you will need to replace the hubs in the front
