Should hubs be locked or free?
As a seasoned auto service provider, I often encounter questions about the best practices for vehicle maintenance. One common topic that arises is whether hubs should be locked or free. This decision can significantly impact your vehicle's performance, especially in specific driving conditions. In this article, we will explore the implications of both options and provide guidance on when to use each.
Understanding Hubs
Hubs are critical components of your vehicle's drivetrain, connecting the wheels to the axle. They play a vital role in transferring power from the engine to the wheels, allowing your vehicle to move. Depending on the type of vehicle and its intended use, hubs can be designed to be either locked or free.
Locked Hubs
Locked hubs are typically used in four-wheel-drive (4WD) vehicles. When engaged, they connect the front wheels directly to the drivetrain, providing maximum traction. Here are some key points about locked hubs:
- Improved Traction: Locked hubs are ideal for off-road conditions, such as mud, snow, or rocky terrain, where additional grip is necessary.
- Increased Control: Engaging locked hubs allows for better control of the vehicle in challenging driving situations.
- Fuel Efficiency: While locked hubs provide better traction, they can decrease fuel efficiency when used on paved roads due to increased resistance.
Free Hubs
Free hubs, on the other hand, disengage the front wheels from the drivetrain when not in use. This setup is common in two-wheel-drive (2WD) vehicles and can also be found in some 4WD systems. Here are the benefits of using free hubs:
- Enhanced Fuel Economy: Free hubs reduce the load on the engine, leading to better fuel efficiency when driving on highways or smooth surfaces.
- Less Wear and Tear: By disengaging the front wheels, free hubs minimize wear on drivetrain components, extending their lifespan.
- Versatility: Free hubs allow drivers to switch between 2WD and 4WD as needed, providing flexibility for various driving conditions.
When to Use Each Option
The choice between locked and free hubs largely depends on your driving habits and the conditions you frequently encounter:
- Use Locked Hubs: When driving in off-road conditions, such as during winter storms or on rugged trails.
- Use Free Hubs: When driving primarily on paved roads or in conditions where traction is not a concern.
Conclusion
In summary, whether to lock or leave your hubs free depends on your specific driving needs. Understanding the advantages and disadvantages of each option can help you make informed decisions that enhance your vehicle's performance and longevity.

Frequently Asked Questions
Should my hubs be in auto or lock?
Generally the hubs should be in auto unless you know the auto lock doesn't work and you want to be in 4 wheel drive. Some say you can run the hubs in lock safely although you increase wear on some front axle parts. I wouldn't unless you use 4wd a lot.
How can I save gas in my manual transmission?
Pay attention to the tachometer, which shows engine speed. Use it to know when to shift a manual transmission for the best fuel efficiency. The higher the rpm, the more fuel the engine is burning. So shift through the lower gears smoothly and quickly, and build up speed in the higher gears.
Do manual locking hubs save gas?
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.
Can I drive my truck with the hubs locked?
So you can drive with your hubs locked. So if you come out you know if you go on full driving. And you come off a gravel road onto a track. And then you come off that say you got your hubs locked in.
When to lock hubs on 4WD?
If you're going into an off-road area where you could be utilizing the four-wheel drive you should lock the hubs.
What happens when hubs are locked?
When the front hubs are locked, even if no power is sent to the front axle (by means of a transfer case), the turning of the wheels will still spin the front axle, differential, and driveshaft, which puts extra load on the engine.
Which is better freehub or freewheel?
In terms of efficiency, reliability, and convenience, the Freehub takes the crown. It is more efficient, reliable, sturdier, and more compatible with various cassette speeds compared to the Freewheel.
Can I leave my hubs locked in?
The rule of thumb is to leave hubs unlocked in the summer time and locked in the winter time. Having the hubs locks will cost in fuel economy. With hubs locked the front differential is engaged and spinning when the wheels are in motion causing drag.
Why use free wheeling hubs?
In theory, when you have the hubs in the free position and the vehicle in 2wd, it takes less force to move the vehicle over the ground. This is because the front wheels are only being pushed around and not the rest of the front half of the drive train.
Do I need to lock my hubs for 4WD?
And a more effective transfer of power from the transfer case to the wheels. On both front wheels turn the hubs completely clockwise to manually Engage The Locks.
