Should my hubs be locked or free?
Should my hubs be locked or free?
I would recommend you leave your hubs locked while in 2WD during bad weather seasons. This will allow you to shift in and out of 4WD whenever the need arises. Good news is that you will not need to stop for shifting into 4WD – with the locking hubs engaged the drive lines are synchronized.
Can you use 4×4 without locking hubs?
No. There are essentially three valves in the system – the 4wd switch, the left hub, and the right hub. In order to have 4wd ALL three must be engaged. If you close any one or any two valves the differential will spin but you won’t get any power to the front wheels.
Is it safe to leave the locking hubs locked?
Could you leave them locked? Locking hub were invented to engage/disengage the front wheels from the front axle shafts. Idea was to keep parts that were not needed in 2WD mode from rotating in order to reduce mechanical drag and thus save gas. Good idea but the savings are extremely minimal.
How does the front locking hub work on a F250?
If you have an updated Ford model, let’s just say F250, there are both options of manual and automatic front locking systems. The choice is yours that which way you like to lock the hub down. Move into your truck, and here you’ll see a panel showing options of a four-wheeled drive and a two-wheeled drive.
Can a rear wheel drive hub be unlocked?
On a rear wheel drive vehicle (most 4wds) the rear hubs are constantly in a locked position and cannot be unlocked, also the diff is constantly engaged to the axles. When in 2wd (on a 4wd vehicle) with the front Hubs locked, 4×4 need to be selected for any drive to be transferred to the front wheels.
What happens in 2WD with locking hubs engaged?
In 2WD with locking hubs engaged front drive shaft, front diff and front axle, rear drive shaft, rear diff and rear axle are rotating. Front tires are rolling along (since connected to the axle, they make the front drive line parts rotate) – only rear tires are pulling.

What to do if your front hubs are not engaging?
If you held a spanner before, fixing a hub by yourself should be possible. Try to get your hands on a fsm. Before you start spending money on repairs, try to find where the problem is. You can try the following : disengage 4wd and engage both hubs. Try to turn the drive shaft by hand.
