Front wheels were engaged and disengaged from front shafts using Locking Hubs. Gas mileage was increased by keeping parts that aren’t needed in 2WD mode from rotating.
After stopping the vehicle, shift the transmission into 4-wheel drive to use the brakes. Start the vehicle while the brakes are applied, and the transmission will lock up and the brakes will not work.
Before starting the vehicle, wait until the brakes have stopped working.
A freewheeling hub or a locking hub engages or disengages the half shaft of the front axle from the hub.
There are many ways to select four-wheel-drive on part-time four-wheel-drive vehicles. The driver can often choose between 4WD and AWD on older vehicles equipped with freewheel hubs.
When it’s raining or snowing, finding the right setting for your vehicle can be tricky.

How Do Manual And Automatic Locking Hubs Differ?
A vehicle can drive at any speed on a public highway. You should not, however, exceed the posted speed limit.
The safe speed range for your vehicle is 70 miles per hour. You can keep your limit when your hubs lock, but it isn’t a rule.
When the 4WD is engaged and the hub locks are disengaged, nothing much happens. The rotation will not be transferred to the back wheels, however.
When the vehicle is in 4WD mode, the locking hub prevents power from being transferred from the rear to the front.
When you are not using the locking hubs, I recommend disconnecting them. You will be able to drive more quietly on the road because the noise level will be lower.
You can lock the hubs if you need 4WD, but do not unlock them until you’re ready to shift into 4WD.
What Is The Difference Between Locking Hubs And A Diff Lock?
Locking hubs are not the same as differential locks. In 2WD, a locking hub locks both drive shafts together, not the front axles.
Both front and rear wheels are still turning, but the rear wheels are no longer pulling. Rotating parts are indicated by red lines.
Rust, dirt, or poor workmanship are the most common causes of a locking hub not engaging. A professional mechanic should inspect the car if this is the case.
Professionals should be consulted if the problem is with the transmission or transmission case.
All they are doing is locking the axle to the hub. As long as they are not broken, they are locked. It is possible to temporarily unlock the hubs by changing the direction of travel in special cases.
I’m not sure if our hubs work this way. Manually locking them will stop this moment of unlocking if they do.
The hub will lock if your automatic hub system is functioning properly. An axle with an open differential will send power to the wheel with the least traction.
The power goes to both wheels if you have a limited-slip differential.
A “locker” in the axle will lock both axles together like a solid rod between the wheels, and both wheels will turn. Mechanical lockers can unlock when needed, and air or electric lockers can unlock when turned off.
Is it possible to use wheel locks instead of diff locks?
Unfortunately, no. Having true 4WD where all wheels get power has nothing to do with hub locks (manual or automatic). Instead, you need lockers or solid axles front and rear, which isn’t very street friendly. That’s why differentials exist.
A solid or locked axle causes each tire to spin at the same speed and that’s bad in turns because you need the outside tire to rotate faster than the inside or the wheel can slip (the chirp from an axle with a locker in a corner or sometimes a spin-out).
My truck has a no open or limited slip differential, which allows each tire to rotate at different speeds. In a sense, it has 2-3wd.
Rear LS that will hold spinning to a point (1-2 wheels) and open front differential that gives me one more wheel with power. It’s 3wd until the rear LS gives out, then it’s 2wd after one spin.
This eliminates the need to get out and turn the hub lock. What is the purpose of manual hub locks on automatic hubs? If they don’t work automatically, you can manually lock them and get unstuck.
A manual or automatic diff lock
4×4 action or true 4 wheel drive is better for me. Is it possible to lock my auto hub manually? In most cases, no (but in some cases, yes).
The hubs are locked regardless of whether the internal auto-lock is working or not… all they do is lock the axle to the hub. As long as they are not broken, locked means locked.
A 1997 Ford Ranger, for example, unlocks the hubs when changing direction of travel (forward to back, or back to forward).
As a result, you’ll find that your vehicle will be more maneuverable and you’ll have more control over it. At highway speeds, keep your windows and doors closed to increase your gas mileage.
It’s great to have locking wheel hubs. Some people need them for their older trucks, and some applications require them.
If you have a 4×4 with 2 or 3 locking diffs, you may want a locking for looks or additional protection. How do locking hubs work? Free-spinning wheels are prevented by them.
