Nice video, Ian. You inspire me to make more content. Been meaning to make a video about a cheap hack, incase you blow out the locking hub mechanism in a common way. Something my truck seems to do. The diesel ate up all my spares. Something the 460 never did.
One more thing. Did you put a divorced np205 in that truck? I couldn't see. Been looking for one. Want the advantage of the pto, and 4x4 after a gear vendors overdrive. Or a simple "brownie box", if I can find one.
yeah go for it making vids is kinda fun and I love learning from others. Thanks for watching my vids. Sorry the editing and camera work are so so. Hopefully getting better with a new phone and more free time. Just sold my fox body mustang and picked up a 7.3 E350 to build. Maybe it will get 4x4 conversion.... Thanks for watching!
I have a mated SM465/Np205 in this truck. I did pick up a Ranger Overdrive for it tho. Advance adapters used to make it as an over or under drive unit IN front of the old 4 speeds. kind of a cool idea.
in order for your truck to be in 4x4 with manual locking hubs you have to get out, lock the hubs then get back in the truck and then put your truck into 4x4 like any outher truck. but without your hubs locked, and if the truck is put into 4x4 it will not turn the front tires. they must be in their locked position. but. you can leave them locked. in my k20 i topically dont because im not in 4x4 all that often, so i rather not wear my u joints. but most off roaders buy cheep hubs, so instead og breaking your axle. you just break the hub
isn't 4WD and AWD the same? i understood that 4wd and awd full time would distribute the power at around 70 percent Front and 30 percent Rear and 4x4 low is more like 25 percent equal on each wheel
Yeah thats a great point. And most Plow guys or loggers around hear do just that. With my front differential having a locker installed I try not to keep them Locked on the street as it makes turning a little harder.
Still some questions left. You said "rack and pinion" in the front axle. (Which, I think, i sweird. I only know "rack and oinion" in the meaning of "Zahnstange", as in some steering designs. Do you mean a bevel gear?) So there is no differential in the front axle? Then, of course, locking hubs would make some sense, because on non-slippery terrain the drive train would tense up, leading to excessive wear and making steering rather unpleasant, if not impossible. Actually, the same outcome as a locking front diff for all practical purposes. If this (no front differential) were the case, you would NEED to unlock the hubs to drive on non-slippery surfaces. However, this then means you would have either 2wd (as power would still only be transfered to the rear wheels with unlocked hubs even if the transfercase is in 4wd), or the equivalent of 4wd with a locked front diff; but no "normal" 4wd mode with functional front diff. This car could be driven as a 4wd only in offroad applications. Not a very elegant solution. Should this really be the case? I doubt it. If there is a front differential, though, the only purpose appears to be saving fuel onroad. (Which is a very laudable cause, of course.)
Manual locking hubs have differentials. sorry i forgot that part. haha their is no really difference between a manual locking hub and a auto. only difference is that the manual locking hubs fromt drive shaft is not always spinning

I have a 2001 Hilux LN167 and when I put it in 4x4 with the diff locks on it jumps out back to 2H when I set off. 4x4 Low works fine. It does not jump out of 4H when the diff locks are off. Any idea what might be happening? What do I need to look at? Could it be a hub issue?
you could but with it welded it would be hard on the street and real hard to steer in snow and ice on the street in 4x4. For the cost and ease of repair I prefer a lunch box or Lockrite or spartan locker over welding. I got the front locker used for 100 bucks.
If the axle shaft is turning is there a problem with the center section? I have locking hubs and I turn it to free but the axle is still engaged with the hub. Is there something wrong with the axle?
sure you could. but as most offroaders will tell you you can break a hub. Also they make drive flanges or drive pucks to do just that. Some call them drive slugs. IT is how my truck came from the factory. Most Plow guys will keep there hubs locked all the time around here
I'm assuming your 4 wheel drive has open differentials with power to only one free spinning wheel (front & back axles). Therefore, to have power to both wheels, the cheapest way to do this is to have locking hubs. Did I understand this correctly?
No. Looking hubs just means the axle shaft is connected to the hub. Your differential gear set is what controls power to one or both wheels. If you have what I know as lockers, you'd have power to both wheels equally.
My truck does have power to both front wheels because I have a Locker installed in my front differential which sends equal power to both front axle shafts which are connected to both front hubs where the wheels mounts with the locking hubs. IF i did not have a Locker in my front differential then The Power would travel to the wheel with least resistance. IF I did not Lock my locking hubs then the hubs and axle shafts would not be mechanically connected and no power would go to either front wheel.
hey man, I bought an 84 m1009. it's my first project truck. only problem is, I'm not sure what I am doing. but having a project car is what I wanted to do. know any reading material I can pick up, so I can learn as it as you? any tips or advice will be great. thanks A.
It's NOT rocket science. Just explain why even bother locking the hubs in 2h at all and what is happening when you are driving in 2H with the hubs locked as opposed to 4H. No video actually explains what locked hubs is and it can't mean 4x4 because you have 2H with isn't 4x4.
2H only sends power to the rear. 4H or 4L will send to front and rear, but if your hubs are unlock the front diff is spinning but not transferring power to the wheels. The hub in the locked position will lock the wheel to the front axle. If in 2H and the hubs are lock, the wheels will turn the front diff. Bad for gas mileage, bad for wear, but if you rarely use 4 x 4 then locking the hubs in 2H will circulate the diff oil a bit. Just don't do it for long distances.
To be on the safe side...i got an 84 toyo. Just bought it a couple weeks ago. The front axle inner seals are shot. Leaking bad. I have limited time to fix it and plan on driving 8 hours back home with the truck in a coulle weeks. Question is....transfer case in regular 2wd, the front axle shouldnt move, right? Thus the front diff gears are not moving at all...Amd the hubs disengaged, the diff wont move either, right? I want to make sure i wont be burning the gears up in the front diff taking the long drive with barely any oil inside the front diff.
Iggybu that would be correct, when the hub is disengaged the hubs are disconnected from the cv axle thus not spinning anything inside the front differential.
Locking huibs Lock the wheel hubs to the axle shaft. Diferental Lockers Lock the right and left axle shafts together.. Most front diffs nowadays have a Unit bearing so the axles are already turning and oly get 4x4 when the Transfercase is shifted to power them
The wheel hubs just lock the tire to the axle shaft through the hub. The axles shafts meet at the differential taking power from the drive shaft. Placing a locker in the differential Makes it Locked and not diffrenate power. Locking hubs just LOck your wheel hub to the inner axle shaft.
i have a driver hub that keeps trying to lock itself when driving. obviously it never actually does, but it goes from 'free' to nearly locked within a few miles of easy driving. should i replace or is the spring just worn? it is a problem cuz it clicks SUPER loud when this has occured, causing me to stop and free it up again....getting worse over a month. any ideas? never had this issue before and trying to not have to replace the set if i dont need to
can you disengage the rear wheels even on 4H or 4L and just use the front wheels for some situation? or like diengagging bot wheels on side and tractioning wtih the wheels from the opposite side? (I mean like tractionning with the front and rear right wheel only)
+PABLO JORGE they utilize a vacuum pump. What it does is essentially suck on the locking portion to suck it in and out when you engage it. So instead of turning the hub on a manual, the same thing accomplished via the vacuum created. It sucks the little plastic clip on the inside to engage the lock.
Some are also "live." In layman's terms, hubs being permanently locked in with no option to unlock them. There are also centrifugal auto hubs that get activated mechanically when you put it in 4wd, you have to back up in 2wd to unlock them.
I think that's the case on Patrol, the centrifugal ones. It is also noted that with the hubs in AUTO, you can engage 4WD without stopping to up to 40 kph, whereas if you're in LOCK, you can engage 4WD in up to 80 kph. I think that's because in LOCK mode, your wheels are turning the shafts already, despite the transfer case actually not sending power to the front wheels. So there'd be more wear and tear on the front bearings, shafts and hubs, but it would allow you engaging the 4WD in higher speeds. Am I correct?
So if I lock my hubs and keep the gear select in 2x4 that is bad right? The hubs are engaged but not powered? I'm in Wisconsin and snow is coming soon, and I don't want to have to keep getting in and out of the warm truck, to switch to 4x4.
+pinky1933 No it wont do any damage. The hubs are locked, so the turning wheels will turn the axles, diff, and drive shaft. But all those parts are designed to do exactly that: turn. I leave my hubs locked full time and I've never had any issues whatso ever. great video mate!!
+pinky1933 No theres nothing wrong with that. If you're in 2WD with the hubs locked, then the front drive shaft and half shafts will turn as the front wheels do. But because there is no gear engaged to it in the transfer case, nothing happens. If anything it reduces your MPG but only marginally. My hubs are locked all the time. You can too. It stops you from needing to exit the vehicle to set them before setting 4WD.
so again, what is the actual purpose of locking hubs? i don't think the video explained the advantage of them if u can just leave them locked and do the selection from inside the vehicle.
Okay advantages.... When unlocked les parts are turning means less drag better mpg and less wear. Biggest advantage is if u break an axle shaft, u joint or gears u can unlock the hubs and drive home
