Question about 2002 Ford F250 Super Duty SuperCab
Last time i took truck out of 4x4 the light stayed on. auto locking hubs.
today the 4x4 is actually engaged and can not get it out of 4 wheel drive.
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: Ford F150 4x4 Passenger side hub
is the sound like a gear jumping noise?if so check the hub assembly and the spline inside the front differential........more than likely the hub assembly

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.

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.
