Two wheels are driven in a 2WD drive car and 4 wheels are driven in a 4wd or 4x4. But what you are seeing is the effect of an open differential, which essentially gives all the power to a slipping wheel. What you want for slippery conditions is a limited-slip differential, which helps balance things out in slick conditions. I'll go into a bit more detail. At the driven axle is the Differential. What this is, is a set of gears that allow each driven wheel to rotate at different speeds. It does this by using the engines output to drive each axle with equal torque. This is a little counter intuitive, and many people think that it works differently, but this is how it works; an open diff provides EQUAL torque to both wheels. but because the torque is equal, if one wheel sees less force against it than the other, it can rotate faster. This is so that, around corners, the outer wheel can go faster than the inner wheel. The problem is that, in very low traction conditions, one of the wheels may have so little grip that the engine cannot provide much torque, it simply rises in rpm's and spins that wheel, while building so little torque doing so that the other wheel does not move at all; and the car is stuck, as well as appearing to be 1 wheel drive; however, both wheels are receiving equal torque. A limited slip differential does what it says on the tin; it limits the difference in speed between each side, so that the side that does have grip and can move the car can receive proportionately greater torque. These diffs have performance benefits in sports cars too, and are generally seen there, as well as in high-performance AWD systems, such as Audi's Quattro, and Subaru's system. A locking diff, as you can probably guess, can lock the two halfs together completely, forcing them to rotate at the same speed regardless of traction on one wheel or the other. Usually seen on true off-road vehicles and 4x4's. An autolocker is similar to a locked diff, except it has a sort of ratchet mechanism that allows one side to advance ahead of the other. In an autolocker, the two halfs cannot rotate slower than the speed dictated by the input shaft, but a half can rotate faster, so it can still go around corners. Used in 4x4's as an alternative to lockers, but are less nice on the road. A spool is just a bevel gear in place of a diff, it acts like a locked diff that cannot unlock. Useless and possibly damaging on road use, for off-road use only. Also seen on some racecars. The legendary Porsche 962C used a spool. A welded diff is the poor mans spool, a formerly open diff that has been turned into a spool by welding certain bits together.
Well said. Same exact results and backs up everything I said for all practical purposes. But appreciate the great detail and information as well as the time it took to write it all out. Thank you.
In nearly every explanation I’ve seen where it starts out by saying 4x4 is different than 4wd… they never explain the difference. You literally mention 4wd in the beginning then never speak about it again. I cannot tell from your description if 4x4 is different than 4wd.
I was going to mention my buddy's older brothers used to weld the rear end for drag cars. Usless and dangerous on a road that you have to turn. Great video though.
I think the trucks without the locker still are able to get by if the compluter applies the brake to the slipping wheel, and the non slipping wheel gets half the power.. so in effect it is doing the same job as the locked differential, just differently. now if the power is being evenly distributed and all your tires are slipping, well, your screwed, locker or no locker.
The algorithm controlled brake locking diffs are a great thing. Much better than a standard open diff. Now a true locker electronic or air is the real winner because it doesn't require any wheel slip or tire spin to activate. That's a huge factor in snow, mud, sand, etc. That's also the reason the gm g80 auto locker bums so many people out. It requires to much wheel spin to activate and the holes already dug by the time it kicks in. But you are 100% that a algorithm controlled traction system is a huge win compared to all open or even to a g80. I wish the new trail boss came with a a electronic locker rather than the g80. Only reason I'm planning to buy a Colorado zr2 is because I need the true lockers here in the swamps.
3:20 Sir, the moment you said an LSD is like a "soft rear locker," where "you almost get a rear locker" I totally began to FINALLY understand what an LSD does. Also, the explanation of differentials (2 wheels on ice, 2 wheels on the road) helped me out so much. You have a no-nonsense way of explaining things, preventing me from yelling "WHY?!" 😅😅 Thanks!
Two wheels are driven in a 2WD drive car. But what you are seeing is the effect of an open differential, which essentially gives all the power to a slipping wheel. What you want for slippery conditions is a limited-slip differential, which helps balance things out in slick conditions.
ruclips.net/video/yYAw79386WI/видео.html that’s a detail information on how a differential works. When the diferencial is open you can see that if a tire it’s stuck or slower the other tire would spin at a faster rate because the differential is open but both of the tires are getting power the engine is powering sending the power through the drive shaft to the differential and from the differential depending on if it’s locked open or whatever that’s how it will turn the tires
Eloy Rodríguez yep but if one tire slips and spins the other side tire is dead in the water. Proven on a hundred slip test videos unless there is lsd or an lsd algorithm.
Thanks for this. And let me just mention for the indexing and recommendation engines at RUclips that I highly recommend this video to anyone that needs or wants to understand how 4 wheel drive and 4x4 work.
I have a 2014 4x4 Silverado. It has a an auto 4x4 switch on it. I'm going to look if you have explained that. I really enjoyed your video and easy to understand explanation of how 4x4 works. Thanks
@Moses1973 4 auto is a amazing feature for anow covered roads and slippery conditions. As soon as the computer senses and wheel slipping it will automatically and quickly engage 4x4. Then where every settles and safe again it will go back to 2wd
correct. 50% front and 50% rear. but doesn't change the wheel spin with one in back and one in front doing all the work until you active front and rear lockers or have a algorithm of lsd.
No 4 runners have front lockers. Actually no stock toyota has front lockers in any of their vehicles. But if you have a trd off road or trd pro model you have the rear locker and mts and crawl control. If you have any other trim level you have atrac only but atrac is still amazing at getting you unstuck. I just made a video about atrac and mts if you check my toyota play list.
Open diffs, basically sends equal torque to both wheels if both wheels have the same amount of traction. When miss matched the max torque that can go to the wheel with traction is equal to the max torque to wheel without traction with out spinning ex: if you got 1 wheel in the air the max torque that can be sent to it with out it spinning is 0ft lbs so 0ft lbs gets sent to the wheel on the ground. AWD cars also have a open center differential, and if it doesn't have a lock button for the center diff like some AWD cars have, the engine will also only be able to send the amount of torque that the axle with least traction has before slipping to both axles. Some traction control systems will apply brakes to the wheel with least traction which increases the amount of torque to slip that wheel while sending the equal amount of torque sent to the opposite wheel ex: the wheel in the air has brake applied increases the max torque with out slipping to 40 ft lbs, then 40 ft lbs will be sent to the opposite wheel which may not be enough for forward progress so the vehicle will just lurch forward, which is why it doesnt work as well as a mechanical locker.
I would buy a 23. It's proven and rock solid. Toyotas track record for first few years of a new vehicle are not that great. It's a problem all manufacturers have and toyora is no different. I'd personally prefer a 23 over a new 24.
@@Jason-Samko now woikd you buy the trd off road for $42k at my dealership or $53k trd pro? Is it worth the extra $10k spent for the pro with the decals, heated seats, moon roof, rims, bumper, skid plate, fox shocks etc? In your opinion?
@appleztooranges in my opinion the trd off road is the better buy. The bilstein shocks on the off rd are great, and both have exact same capabilities. And since you are keeping it for a while the resell of the pro is canceled out (not that it was a huge difference dollar for dollar).
Would Front and Rear Trutracs apply power to all 4 wheels? I l know in a rock crawling situation its real ineffective, but for most offroad trails and overlanding would dual LSDs apply power to all 4 wheels?
Agree 100% so many people I see stuck in the woods expected the wheels on the high edge of the hole to get them out. Literally heard that a dozen times as I pull them out. They all say "it's 4x4 I figured as long as I kept 2 side wheels high and dry I'd be ok".
@@Jason-Samko next one should be the tools and recovery gear needed before going out. Spend it once and have fun instead of waiting for someone to pull you out and being pissed when they charge an astronomical amount. Thanks again
So how good is the 2024 Nissan Frontier Pro 4X with rear locker and ABLS when it comes to "4x4" ...does the ABLS kinda act like a front locker or does it help out the rear locker? I realize its not a true 4x4, but wanted a little more insight on comparison I guess.
From test i have seen (roller tests and offroad) the frontier has very little computer traction control in the front. Same with ford. Jeep and toyota have amazing computer input. The rest not so much. Check doesn't have much either. They are all basically the same with the exception of jeep and toyota
@ Thank you for the reply. For what I’m using my Frontier for should be more than enough for getting through the little bit of snow and light off roading up here in Southwest Ohio. Loving that ZR2 you got for Tina, that was my 2nd choice behind the Frontier Pro 4X, but I don’t do any serious off road or overlanding as of yet, may be my next truck though. Thx again
@DouglasB65 make no mistake. The frontier is a very good offroader and does a fantastic job. It may not have the computer controlled lsd that jeep or toyota has but it's no slouch and has a great 4 wheel drive system. And like 4x4 used to be you can create your own torque transfer by apply the brake when needed to great more power to the wheel thst needs traction. You asked about the computer abls. So I answered thst. But had you asked if the frontier was good in the snow and offroad my answer would of been absolutely
All the all wheel drive systems have algorithms gm, ford ect.... I had an audi was great in the snow but its a poor mans locker it beats getting out to dig for traction to the wheel thats spinning . Im a truck guy and I wanted a body on frame front and rear locker true 4x4 so I got the zr2, your right there's not many out there , allot of these trucks and SUVs have AWD systems and there great but sometimes you need every tire working together not playing games with the brake calipers sending power everywhere. Even the 24 Tacoma does not have a front locker they cheesed out and give you crawl control thats a way to give you power to every wheel at some point but not every point, and thats why you have to crawl through everything . I found that out years ago when I was a young 4 wheeler before youtube I had to figure it out on my own its like it was a secret back in the day, but most of your snow plows are trucks with lockers and they get serious traction .
The zr2 is the only chevy truck I'd personally buy for my needs as it has front and rear lockers. The g80 is great but not enough for what I need and gm trucks don't have and algorithms u til you get into the upper canyons trims I believe. Love the zr2 and bet you are loving it to!
My Toyota TRD pro will lock everything, front and rear.....so does my '94 chevy off road addition if you have it in 4WD and in low gear, or if the transfer case is in low.
g80 is a great option. but not good in snow mud or sand or rocks or really anywhere that requires slow movement to get out becuase the g80 requires the working wheel to hit 100 rpm before the g80 engages and when it engages its hard and jerky. but much better than not having it. A true locker is best if you can get one.
@SamkoWorkShop i agree. I was more talking about factory options without spending big money 💰. I have an '81 k20 with a G80. Seems like the older ones work better than the newer ones. Just guessing based my limit experience.
Craig Marsh I bet it does work better back then and I'm guessing it engaged faster. They probably slowed it down to prevent lawsuits if it engaged to quick on slippery roads etc.
In Utah, there is a very steep road to Powder Mountain ski resort where my brothers and I grew up skiing. If you figured out how to use your little front wheel drive car, you could pass people with 4WD on a steep snowy road. 😂
So the diff has to open what about lunch box lockers or ratchet lockers I have both in my three jeeps or factory posi or sure grip (mopars idea of locker) or torsen diff Mazda's locker some work better than others the point is diffs absolutely don't need to be open Edit let's not leave out jeeps quradtrac they will move with one tire on the ground
I left out lunch box lockers to keep it simple and since most ratchet or lunck box lockers are after market only now. But they do work good but can be dangerous on slippery roads.
@samkoworkshop1513 yeah there aftermarket for the most part well except it's what is is in semi truck front tandem axle diffs cause there not power unless u lock the power divider
very true! I left out the HD trucks as they are not really good in the woods due to their size. at least not here in the east where its tight. But you are 100% correct. and the power wagon has front and rear lockers too.
@@RM-bx2zt yep should be mandatory on all trucks but especially on the expensive ones! Just got done making a video about how 100k truck prices are getting out of hand and the stupidity of how little get get for that kind of money
How come you guys didn't drive with front and rear lockers on and stop on the hill like you did on the other 4X4's. Questionable to say the least. Please explain.
2 different trucks. and i was showing a clip from a previous video i made about the limited slip button in 2wd with my tacoma. the video with the zr2 that haad front and rear lockers was not mine. I explained it all in the video. not sure what was questionable about it. I could of got up the the hill in my tacoma even in 2wd with just momentum if i wanted to. but i was making a video and proving a point.
Cause when you have lockers they tend to get wheel hop, axle in rear wants to twist that what traction bars are used for, to prevent the truck from Monday the hop up and down
Me and my friend barried our trucks in the sand and he has front and rear lockers. I turned on atrac and got out,he engaged lockers and barried his truck. So yea js
Yes and Tremor F-150 & Super Duty, and G-wagon, and Ineos Grenadier, for starters. Also Ford offer the Torsen front locking LSD through it's performance catalogue to fit on any of it's F-150's with warranty.
@@fabulousoffroaddesigns5080 yep those are all all top tier vehicles 90% of people can not afford. Shame they dont offer lockers on vehicles for us common folk.
@@Jason-Samko well you can buy a 2007 or newer Ford F-150 and take it to your Ford dealer to add the front Torsen diff as a factory approved/dealer installed front hard locking LSD, and it is way better then a front E-locker and almost anyone can afford it if they choose to.
The title, the way you have your chart, and the way you explained this will be misleading for many noobs. Fact is 2WD = 2WD = 2 wheels are receiving power and 4WD = 4WD = all 4 wheels are receiving power. That ONLY changes IF you are stuck or spinning, or hard cornering, in basic differential systems. You are going to lead noobs to think that only 1 wheel is being powered in their 2WD cars etc. And as you touched upon, many vehicles have LSD or Posi, locking diffs, or advanced AWD systems that send the power where it needs to go. But generally speaking when driving a car under normal conditions 2WD = 2WD and 4WD = 4WD. There is, after all, a reason they DON'T call a 2WD a 1WD or a 4WD a 2WD ;)
It's not misleading when look at the thumbnail I used. I didn't show a truck going down the road. And most people want 4 wheel drive for slippery conditions. In those conditions everything I say is 100% true. And I talked about lockers and lsd etc. Things that most vehicles still don't come with especially trucks and suvs.
It’s not really misleading when you consider that many things are expressed in terms of performance in worst case scenario, which is where the actual “rubber meets the road” so to speak (pun intended). In the worst case scenario, indeed a traditional 4x4 acts like a 2x4 in terms of wheels receiving usable power.
Kia AWD, but its not. The ONLY tIme the rear is involved, is when the front slips. Thats NOT AWD, thats part time AWD. Now to be honest, I live in Ice and Snow country. It has legitimately taken my stupid ass everywhere I have ever pointed it and never gotten stuck.
Not really as a 4x4 is double the capabilities As a 2wd truck. But the reality of open differentials is a real eye opener when you realize how they work.
A center locker just means that when you go into 4 low and engagement the center lock its a true even power distribution to the rear and to the front. still have the same problem with one wheel in front and one wheel in back doing the work. but the front end get 50% and the rear end gets 50%

I am also new to the 4X4 world- I really appreciate this information... I did not know this stuff.
@@malachi487 glad you enjoyed it
Had no idea you could have a 4x4 without the lockers, great info thanks for sharing.
Very few trucks today have them unless ordered on a special offroad package. And very very few have both front and rear lockers
@@Jason-Samko my 19 ford ranger FX4 has a rear locker better than nothing.
@JustAverageJeff love the fx4 package
very well explained, very good.. Thank You.
Glad you enjoyed it
Awesome info man! Thank you….
Glad you enjoyed it
Thats why the GM g80 is the desired diff. Just go to any wrecking yard, they are hard to find.
g80 is a great option. but not good in snow mud or sand or rocks or really anywhere that requires slow movement to get out becuase the g80 requires the working wheel to hit 100 rpm before the g80 engages and when it engages its hard and jerky. but much better than not having it. A true locker is best if you can get one.
@SamkoWorkShop i agree. I was more talking about factory options without spending big money 💰. I have an '81 k20 with a G80. Seems like the older ones work better than the newer ones. Just guessing based my limit experience.
Craig Marsh I bet it does work better back then and I'm guessing it engaged faster. They probably slowed it down to prevent lawsuits if it engaged to quick on slippery roads etc.
In Utah, there is a very steep road to Powder Mountain ski resort where my brothers and I grew up skiing. If you figured out how to use your little front wheel drive car, you could pass people with 4WD on a steep snowy road. 😂
Front wheel drive always does great in the snow with all the weight of the motor over the drive wheels and pulling rather than pushing.
Thank you, kind sir. You made it easy to understand.
Glad you enjoyed it
Never knew this. Thank you!
Glad you enjoyed it
So the diff has to open what about lunch box lockers or ratchet lockers I have both in my three jeeps or factory posi or sure grip (mopars idea of locker) or torsen diff Mazda's locker some work better than others the point is diffs absolutely don't need to be open
Edit let's not leave out jeeps quradtrac they will move with one tire on the ground
I left out lunch box lockers to keep it simple and since most ratchet or lunck box lockers are after market only now. But they do work good but can be dangerous on slippery roads.
@samkoworkshop1513 yeah there aftermarket for the most part well except it's what is is in semi truck front tandem axle diffs cause there not power unless u lock the power divider
the tremor f250 and f350 have a front lsd
very true! I left out the HD trucks as they are not really good in the woods due to their size. at least not here in the east where its tight. But you are 100% correct. and the power wagon has front and rear lockers too.
the ford torsion lsd is pretty awesome though and closer to a locker.
I hate when i experience this. I knew why and it was not a help. 4 wheels on ice with BFG ATs. Went to studded snows in winter. 😀👍
Yep I think a rear locker and some sort of computer controlled limited slip in the front should be mandatory on all 4x4 trucks
It would make more sense than leaving people who spent $80,000 on a 4WD stuck.
@@RM-bx2zt yep should be mandatory on all trucks but especially on the expensive ones! Just got done making a video about how 100k truck prices are getting out of hand and the stupidity of how little get get for that kind of money
That’s a great way of explaining it
Thanks
How come you guys didn't drive with front and rear lockers on and stop on the hill like you did on the other 4X4's. Questionable to say the least. Please explain.
2 different trucks. and i was showing a clip from a previous video i made about the limited slip button in 2wd with my tacoma. the video with the zr2 that haad front and rear lockers was not mine. I explained it all in the video. not sure what was questionable about it. I could of got up the the hill in my tacoma even in 2wd with just momentum if i wanted to. but i was making a video and proving a point.
Cause when you have lockers they tend to get wheel hop, axle in rear wants to twist that what traction bars are used for, to prevent the truck from Monday the hop up and down
Me and my friend barried our trucks in the sand and he has front and rear lockers. I turned on atrac and got out,he engaged lockers and barried his truck. So yea js
And that is another reason I have a Super Duty Tremor !
Beautiful truck
You just found this out....welcome to the 60s......your just comin out of the stone age🤠😎🤓
im 50 years old. Iven know it for decades. but now that I have a channel with a voice I wanted to share and help people.
Thank you Dr. 4wd. Enjoyed it
Welcome. Glad you enjoyed it
This is why I have a rubicon. ✌️
Rubicon is amazing with the front and rear lockers
Vien explicado gracias
Glad you enjoyed it
Great video. I am a mechanic and most people, even some 4x4 enthusiastic, dont know. By the way the power wagon Ran also has front and rear lockers
100% correct. the power wagon, the tremor 250 and 350 also have a version of front lockers even if just torsion lockers.
4x4, 4wd, awd... still better than 2wd at a stop light in the snow. You go and they're left spinning especially on an incline
Correct. Cause 2wd is really 1 wheel drive and 4wd is really 2wd in those conditions so you ate actually doubling your traction.
I think the dodge power wagon comes with front and rear lockers
It sure does! you are 100% correct
Yes and Tremor F-150 & Super Duty, and G-wagon, and Ineos Grenadier, for starters. Also Ford offer the Torsen front locking LSD through it's performance catalogue to fit on any of it's F-150's with warranty.
@@fabulousoffroaddesigns5080 yep those are all all top tier vehicles 90% of people can not afford. Shame they dont offer lockers on vehicles for us common folk.
@@Jason-Samko well you can buy a 2007 or newer Ford F-150 and take it to your Ford dealer to add the front Torsen diff as a factory approved/dealer installed front hard locking LSD, and it is way better then a front E-locker and almost anyone can afford it if they choose to.
Nice explanation
@@romelbosio5838 glad you enjoyed it
This is an absolutely terrific explanation. Wow this was good!
Thank you. Greatly appreciated and glad you enjoyed it
FYI it's "misled".
Yep I suck at spelling
The title, the way you have your chart, and the way you explained this will be misleading for many noobs. Fact is 2WD = 2WD = 2 wheels are receiving power and 4WD = 4WD = all 4 wheels are receiving power. That ONLY changes IF you are stuck or spinning, or hard cornering, in basic differential systems. You are going to lead noobs to think that only 1 wheel is being powered in their 2WD cars etc. And as you touched upon, many vehicles have LSD or Posi, locking diffs, or advanced AWD systems that send the power where it needs to go. But generally speaking when driving a car under normal conditions 2WD = 2WD and 4WD = 4WD. There is, after all, a reason they DON'T call a 2WD a 1WD or a 4WD a 2WD ;)
It's not misleading when look at the thumbnail I used. I didn't show a truck going down the road. And most people want 4 wheel drive for slippery conditions. In those conditions everything I say is 100% true. And I talked about lockers and lsd etc. Things that most vehicles still don't come with especially trucks and suvs.
It’s not really misleading when you consider that many things are expressed in terms of performance in worst case scenario, which is where the actual “rubber meets the road” so to speak (pun intended). In the worst case scenario, indeed a traditional 4x4 acts like a 2x4 in terms of wheels receiving usable power.
Wilys dont have those before. But they are calle 4x4 vehicles
Thanks for breaking my heart😞
Crazy how 4x4 works in reality
Kia AWD, but its not. The ONLY tIme the rear is involved, is when the front slips. Thats NOT AWD, thats part time AWD. Now to be honest, I live in Ice and Snow country. It has legitimately taken my stupid ass everywhere I have ever pointed it and never gotten stuck.
Front wheel drive always does better than rear wheel drive because the weight of the motor sits over the front wheels adding weight for traction.
Originally 4x4 was 4 speed manual transmission and four wheel drive..
Interesting and did not know that
So basically all 4x4 truck are a scam unless you have after market parts your truck is useless
Not really as a 4x4 is double the capabilities As a 2wd truck. But the reality of open differentials is a real eye opener when you realize how they work.
You are missleading what 4x4 is
Explained exactly what it is and how it works in simple to understand terms in the video
my 1991 quattro was better than this, without the need of any electronics.
This applies to American crap
Yes it does and all the imports we get here.
My Toyota 4Runner is AWD and has a “center diff locker” so I’m still lost lol
A center locker just means that when you go into 4 low and engagement the center lock its a true even power distribution to the rear and to the front. still have the same problem with one wheel in front and one wheel in back doing the work. but the front end get 50% and the rear end gets 50%
Turn off all your nannies and itll be fine
Glad you enjoyed it
Go back to school wheels are opposite of each other’s
Appreciate the comment
