What does a locking hub do?
Locking hubs, also known as free wheeling hubs are fitted to some (mainly older) four-wheel drive vehicles, allowing the front wheels to rotate freely when disconnected (unlocked) from the front axle. The hub is a component where the wheel is directly mounted to, and is outside the axle.
When should you lock your hubs?
When to Lock your Hubs If you drive mostly on bitumen and only choose to run with the hubs in the free position, then it’s recommended to lock the hubs occasionally to provide ‘splash lubrication’ to the drive shafts. Some owner’s manual recommends driving at least 15km / 20km per month to provide lubrication.
Is it bad to drive with your hubs locked?

The 4×4 Hubs on a vehicle is the device which engages the axle to the differential. Without the hubs there would be no drive sent to the wheels. To be in 4 wheel drive they need to be locked and the 4×4 selected, this will transfer 25% drive to each of the 4 wheels.
How do you engage manual 4×4?
You engage 4WD in a manual transmission Jeep by depressing the clutch and shifting the 4WD gear shifter into 4H. Always ensure you are not accelerating while doing so and give the 4WD shifter a firm yank to ensure it engages fully. When engaging 4L (Low Range) you need to drive as slow as 2-3 MPH.
What are the benefits of manual locking hubs?
What are Manual Locking Hubs? Manual hubs are a type of part used to disconnect a wheel from an axle in a four-wheel drive system. This allows the wheels to rotate without having the front driveline turn. This saves wear and tear on the vehicle and also helps improve fuel economy.
Does it hurt your truck to drive in 4 high?
Extended driving in 4-Hi, with a part-time 4WD truck, on a high traction surface like pavement, will result in drive-train components like u-joints, axle, transfer gears, bearings, and drive-shafts getting damaged and eventually failing.

Can you drive in 4wd 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.
What is the function of locking hubs?
The function of locking hubs is to engage or disengage the front wheels from the front axle shafts present in four-wheel drive vehicles.
Another benefit for manual hubs: you can run a front locker on the street and it would be easier to drive. I have used the Warn Auto locking hubs on past rigs and they were nice to have in nasty weather. Of course when I was living in the Pacific Northwest my hubs stayed locked in during the winter.
What do lockout hubs do?
