What do manual locking hubs do?

- A quick demonstration of the function of a manual locking hub. Manual locking hubs can exist on solid axle vehicles as well as vehicles that use cv axles. By unlocking or disengaging the hub in 2wd, you obtain better fuel economy as you don’t have the drag of the front drivetrain that’s not needed. In 4wd, you would want to have the hubs locked or engaged to use 4wd. If unlocked in 4wd, you basically have yourself 2wd vehicle as the front axles can’t turn the front tires. Note that some vehicles have automatic locking hubs that don’t require turning a knob and some vehicles don’t have selectable hubs and are always “locked”
Hubs shown are Warn 29091 Premium locking hubs for certain 28 splined vehicles (verify your vehicle's fitment)

thank you for this video. i found it after watching like 5 different videos and you are the first to explain what the hell is going on. thank you
Most concise thorough explanation on you tube, thanks
One minute, this is what CZcams is about. Had a pretty good idea what it does, but never seen it live, so now I know for sure. Thanks. 👍
Thanks for posting. I recently bought a 76 GMC Jimmy with locking hubs. It's my first four-wheel drive vehicle and the first truck I've ever owned so it's a whole new world for me.
Such a simple but effective demonstration of the principle. Great video :)
Exactly what I was looking for. Sweet and simple.
I knew all your hair cut boys wur dumbbb
BRILLIANT.
SIMPLE.
10/10.
Thanks for the explanation, that’s a nice locking hub setup you have there
Thank you - explanation crystal clear👍
Thank you! so much better description than how Cengage was explaining it!
Thanks, simple to the point
Having access to low gears without engaging 4x4 is nice to have when towing jeeps back to the staging area.
Most easy explaination👍🏻 appreciate it
nice. straight to the point
what does that do when it's locked vs unlocked
Best vid by far. thanks
Perfect. Exactly what I needed and in clear terms with a perfect demonstration. Non-Sequitur: Can you recommend a truck tire that will be good for improving MPG/fuel efficiency but is decent in snow?
Pick one. Anything good in snow is going to be knoby. Knoby = wind resistance/noise = poor mpg.
I gotta say thank you too 👍🏼
Perfect. Thank you
I don’t get it. I get a clicking sound I read a form that means it’s locked I turn it the other way and don’t get a sound but in your video unlocking them gives you that click
So is a locking up like a locking diff for but for the front?
My rwd ranger has an open differential, sometimes I need both tires to get power, generally in the snow. One tire spins freely, the other doesn’t move. If I put locking hubs on the rear, would it force both tires to get torque? I don’t want to spend $1500 on an Eaton e locker. My truck has the ford 8.8 rear end
I'm not aware of any manual locking hubs for rear axles. However, if there was, unfortunately this wouldn't be the solution you're looking for. Think of these hubs unlockers. There handy if say someone with 4wd had a welded front diff and they wanted to take it for a spin on the streets, they'd unlock the front hubs to allow front tires to spin freely at different speeds on the streets for easier driving. E-lockers are definitely pricey, maybe there's some limited slip options for less than might be better bang for your bucks. I'm currently running a junkyard limited slip that I got for about $100. Works great in bad weather
Where this function helps us in offroad or for mileage purpose???
This particular part of the vehicle doesn’t necessarily add any additional off road performance. Performance wise, it’s the same as vehicles with automatic hubs or “always on” type of hubs. The benefit to it is that it allows you to stop the front wheels from constantly spinning the cv axles and front drive shaft when you’re in 2wd mode. When you add up the weight of the two cv axles, differential gears and front driveshaft, that’s dozens of pounds of dead weight being turned mile after mile.
@@dospathsgarage2854 thanks bro for information 🙌🙌
if both are locked, is central differential works equal for right and left tyres? especially when turning?
Better to put Manual locking hubs for both front tires?
Sweet
Can I install manual locking hubs on a 3rd gen Tacoma? In 2wd, this would have the effect of not spinning the CV axles while the truck is in motion.
These particular hubs shown won't work on a third gen Tacoma. A quick glance at Tacoma forums indicates that third gens don't need manual locking hubs. Something about an automaticlly disconnecting diff was talked about
So does this mean, any idiot can come up and Lock/Unlock them when your truck is parked? Is there any in-cab indicator, I've recently learned that keeping them locked position can cause the driveshaft to fail since it's not connecting to the transfer case.
No in-cab indicator on these unless a vehicle has a particular noisy front driveline to indicate they are locked
What is the benefit of this? Is it so you can have the rears in 4L or 4H without the front engaging? When will this be beneficial? Thanks...
Hanging off a dune or rocks where you just need rear power to level out without the front digging is my guess don’t take it as fact tho
Could anyone help me out or have an answer to this question? So I have a full-time transfer case on my 6spd Toyota FJ Cruiser and I’m wondering if I do a manual locking hub conversion will it ruin anything on my front drive line cause even though the hub won’t be engage if I do this manual locking hub conversion the axle will still be rotating in the hub since I have a full time transfer case or is this not a good idea. Any help or opinion or is appreciated.
This works or fits subaru forester 2002 .. ? Or where can find exactly for ? Thanks for the help 🙏
Sorry, hubs shown are for Nissan and a few other manufacturers but not Subaru.
Fascinating!
if i put the hubs to locked, and then i switch from 4x4 to 2x4 in the excursion, will the hubs physically tilt over to free?
No, they hubs would still remain locked even in 2wd
i don't understand why would you do that if you put it on cars the already aren't full time 4x4. what do you get from this?
In my case, I’ve lifted the vehicle which puts the cv axles at an angle near their limits. This reduces some wear on them from my daily city driving and gives a slight mpg boost
You need to watch the ramman.
The Point behind this fuel economy.
No wear and tear on Drive shaft rest of the moving parts. When the Hubs are Locked Out! Little better Fuel economy.
Locking Hubs on 4x4 have bean around for years!
Auto makers Stopped Putting Locking Hubs
on there vehicles because the public got Lazy!!
To get out of the vehicle to turn the Hubs.
does this hub lock makes both tires spin at the same revolution. So if one tire loses traction diff won't send all the torque to that tire.
No, this hub doesn’t lock the differential between the two wheels, so one wheel can still spin if it loses traction. That would be a differential locker or limited slip to keep both wheels spinning the same speed
@@dospathsgarage2854 how about lunch box lock? That's a hub lock too right?
@@babayaga9102 From what I’ve read, a lunchbox locker is for the differential that locks the wheels to spin at the same speed under slipping conditions. They make clicking noises when driving on streets (which is fine) but some people don’t like the noise they make on the street. But other than that everyone seems to like the lunchbox type differential lockers
❤️♥️
Should i remove front shaft or use a free wheel hub, which is better for fuel economy an convenience ?
Removing front shaft would pretty much give the same fuel economy but it’s not as convenient as using a free wheel hub
Is is effective at all to lock only one side if the other tire is slipping ?
No, it wouldn't help with traction in that scenario
is my understanding correct that manual hub lockers only apply to front wheels?
Yes 👍
So does that mean a front diff lockers wouldn't work without a locking hub?
Not necessarily. If vehicle has a front diff locker and is not equipped with manual locking hubs, then the front diff locker would work as intended. If the vehicle had a front diff locker and is equipped with manual locking hubs, the hubs would have to be engaged in order to use 4wd(with locker) or else the vehicle would still effectively only be 2wd
Hey there, I just bought a 96 F150 with the manual hubs. I was curious, based on what I'm seeing, even if 4x4 isn't engaged is it safe to leave the hubs locked for short periods of time? For example if I know I'll need 4x4 in spots on a 20 minute drive, say winter backroads, could I leave the hubs locked for that 20 minute drive or should I get out and lock or unlock them each time I switch in and out of 4x4?
I'd bet you're safe to do that in the ford. Unless the owners manual says not do it, I'd run 2wd with hubs locked since I've been doing it for a couple years on the old Nissan without issues
@@dospathsgarage2854 Fair enough. I'll have to try it and see how it goes. I appreciate the quick response!
Is it alright to drive on normal road and highway in 4H when the hubs are free?
Most old school 4x4 would probably be fine. Some newer electronic systems may not like it. Just depends on the vehicle's transfer case design
what happens if you run them in looked all the time?
Constantly running locked would result in a slight fuel efficiency decrease. For me, the cv axle bolts will wear out faster since my lift puts the cv axles at an angle that flexes the boots quite a bit
What vehicle is this?
It doesn't replace a diff lock right?
Correct
@@dospathsgarage2854 Adding locking hubs won't turn an open diff into a locking diff. You still need the diff locker if you want to send power equally to both front wheels.
And that’s why I lock one side and leave the other unlocked. Ford owners 😂
So when it’s unlocked. The cv axles still spin? Then if it’s spinning freely all the power will be at the front axles without center lock diff?
If it’s unlocked, the cv axles will remain motionless when driving in 2wd mode. If 4wd is activated with hubs unlocked, the cv axles will be turning via transfer case and driveshaft but the axles will not actually power the front wheels since the hubs are unlocked. The vehicle would behave as if it’s in 2wd mode. If this were to be done with an awd vehicle, the results could vary but that’s a more complicated matter
@@dospathsgarage2854 thanks
It can be fixed on GMC 1997 2 door
@@dospathsgarage2854 Some people online are saying that in winter, they'll keep the hubs locked and engage 4WD when needed. Is this an okay thing to do? And can it be done while the vehicle is in motion going down the highway? Or do I need to stop first?
@@sethmoking yup, I myself will lock the hubs and leave them locked when the weather is wintery. This makes it where you don't have to step out of your ride to lock them if you decide you suddenly need to use 4wd. Some transfer cases require you to be stopped or a super low speed to shift into 4wd, where's some allow you to shift into 4wd while driving. Either way, you get the stay in the car. Downside is you might have a slight mpg decrease because the front axles are introducing drag as they rotate with the front wheels when locked
Do you know the lenght of the 29091?
Somewhere between 3 3/4 inches to 3 7/8 inches. Hard to tell without taking the wheel off to measure
How does that chintzy knob lock a drive axle into the hub? Also, why is there sometimes THIS and also a 4x4 transfer case selector inside the car ? In what scenario would one be using BOTH Zoe these systems? Is it not redundant? Curious :)
Great questions actually. While the outer cap on these hubs is relatively thin compared the base and internals, the outer cap just moves a beefy sprocket to or away from the splines on the ends of the cv axles. This particular model and most modern 4x4s don't have manual locking hubs from the factory. Many times the cv axles mated to the drive hubs (this vehicle was like that originally). Cv axles and differential internals will always be spinning even in 2wd. Fuel economy suffers slightly and miniscule wear and tear occurs on extra moving parts. Another type of design includes automatic locking hubs. They look somewhat similar to these except there's no knob to turn. They use some sort of sprocket voodoo to engage or disengage. Some versions require driving forward or backward a few tire rotations to engage or disengage. Mud or corrosion can make them unreliable at times though. Some vehicles electronic hubs or actuators to engage or disengage either the wheel from the axle or disengage the axle from the differential. Some people with automatic or electronic hubs switch to manual hubs for more reliability or increased strength. Others without manual/electronic/manual hubs switch to manual because they seek fuel economy by not turning the front drive line in 2wd. Off-roaders can have niche reasons as well. For example, I have an automatic differential locker in my front diff that makes audible clanking noises (by design) even in 2wd. I can keep it quiet in 2wd by isolating the differential from my front wheels by using these hubs
@@dospathsgarage2854 YES! Fantastic response. Thank you so much. You rock
@@dospathsgarage2854a year later reading this again. Still amazing. Thanks so much haha
@@dospathsgarage2854 I would imagine that if you unlock the front hubs, you'd need to lock the center diff, otherwise you won't get full power to the rear diff. Most all wheel drive cars don't have a locking center diff.
Is this a 89 4runner?
2nd Gen Pathfinder
: )
is unclocking the hub will make the engine brake disappear?
No because the rear wheels will still be engaged
@@dospathsgarage2854 Should i remove front shaft or use a free wheel hub, which is better for fuel economy an convenience ?
Can I install manual hub on my fulltime 4x4 (lc80)?
Not sure, but probably. When bolted up, the hub would provide the same functionality as demonstrated in the video whether the vehicle uses cv axles or solid axles. One thing to make sure of is whether your full time 4x4 or awd transfer case can operate without the front axles rotating in 2wd. It’s possible that a part time 4x4 or awd transfer case needs front axle movement to keep parts lubricated or prevent sensors from freaking out. I would suggest checking with a Landcruiser forum for a more certain answer.
@@dospathsgarage2854 great answer dude
So does it lock in both front wheels forcing them both to “drive”? Or is it still like a limited slip?
Think of it more as "disconnecting hubs" as in it disconnects the front wheels entirely from the drivetrain when they are "unlocked". With them locked, it's simply reconnects them to the front drivetrain. It's more for fuel savings when driving in 2wd. The front differential can still be a typical open diff, limited slip or even a locker
