[@robertjolley4354]

I’ve been an automotive master technician for 20 years and this video does a good job of explaining a subject a lot of people have a hard time understanding. Everyone wants to weld the differential until they realize you can only drive it in a straight line to keep it from breaking.

[@177SCmaro]

I had a spool in my race car (manual steering box, btw) for a few years and it was awesome on the drag strip but sucked royally everywhere else. Especially with slicks the car seemed to go through agony every time it had to make a sharp turn. The fact that our strip has two 180 degree turns, one on one off, colored my attitude towards them somewhat. I've since got a Detroit locker and it's so much easier on tires and the car. I don't feel like he frame is trying to twist in half anymore.

I daily a diesel Ford pickup with welded diffs in both axles. Unlock the front hubs before you drive anywhere and it’s literally not an issue. Since I’ve welded them that trucks put 20k miles on the odometer.

[@oldowl4290]

Can I ask you a question? I have a really nice 2015 XB 5-spd. Actually the last one off production. I thought it came stock with an LSD but from what I've found it's probably and Open diff. Is it really worth it to upgrade? I have a full shop at my house, have done engine rebuilds before and clutches but not a diff yet. I've also read that to really get the benefit you should supercharge or turbo the car, otherwise it's a waste of time and money. Would that be your consensus. It is a box lol, but it's actually got every Toyota/TRD aftermarket part available. I bought it at 40k miles and the original owner had really dialed it in save for engine/trans mods.

[@javm2825]

There is one element you missed when explaining the welded Differential during corner exit. With the Weight Bias shifting to the rear wheels, the traction is less on the front than both of the rear wheels so the traction can cause the Front Wheels to be the ones to slip, not the inside rear. As such the car will now understeer drasticly.

[@derucktorez2260]

Happens on poorly designed go karts. It's called "plowing". Happens because of a solid axle rear end, and a poorly designed steering setup. In some cases you can't get it to stop in suspension applications. So that really makes sense how the weight distribution would make such a thing happen. On a kart with no suspension it's easy to fix. But when you add suspension, it gets to be a headache.

[@roysoutdoorlife]

​@@derucktorez2260 I used to race 250 gearbox karts (or shifter karts as they say in the USA!). They were set up to lift the inside rear wheel on corner entry to get the kart turned in, then drive out of the corner on the throttle with a subtle drift. Not too much drift or we'd lose too much speed. It was a bit of an art to balance them but at least we had gears to help, unlike the direct drive karts where momentum was king. Good fun though!

[@gedavids84]

I watched the first video all the through and thought it was a little oversimplified in some places, but pretty good. This video is a significant improvement, well done.

[@jakemustian99]

Weight transfer is not necessarily in the opposite direction of movement, but the oposite direction of acceleration. If you are moving forward but press the breaks, the weight transfer is forwards because the acceleration is backward. Same as in a turn. The cars acceleration is toward the center, thus the weigh transfer is to the outside of the turn, which is actually perpendicular to the direction of movement

[@caty863]

For cars equipped with an ABS, an open differential is enough since the ABS equipment can be used to restrict the movement of the slipping wheel thus increasing the torque sent to the other wheel.

[@PaulSpades]

All ABS does is limit breaking force. Not all systems limit each wheel independently, and none of this controls torque unless you're both breaking and powering trough a corner. Traction control systems actually do modulate breaking on each wheel to control traction in that scenario, but still don't modulate torque sent to each wheel. The only systems that actively control wheel torque are LSDs and they can be electronically controlled. This video explains why they exist, and they're made to do the thing they do. They're not snake oil.

[@hazza2247]

@@PaulSpadesif traction control notices that one wheel is free spinning (such as on ice like in the video) and applies brakes to just that one wheel, then all the engines torque will go to the wheel with good traction through an open dif, but if ur gonna do all that then u may aswell just have an lsd

[@BradGryphonn]

I was a truck driver for many years, and most vehicles I'd ever driven (truck or car) on unsealed roads were rear-wheel drive. Therefore, I got used to how those types of vehicles reacted on said roads. In the 90s, I started working for a company that made urgent deliveries to coal mines West of where I lived. One day I was in a small, front-wheel drive car delivering some small, yet extremely urgent parts to a mine, along a loose gravel haul road. The haul road was wide. Probably about 50 metres (approx 150 feet) I guess. I was tooling along in this little car at about 120kmh and came to a long, sweeping bend. As I entered I backed off a little and the car stopped following the bend and decided to start skating across the gravel. Now, in a rear-wheel drive vehicle that wouldn't happen due to the inertia of the rear, and if it did, you just give it time to correct before adding any 'gas'. So, I stayed off the gas and the car kept sliding along. I then remembered some side comment I'd heard from a bloke who I knew who played with FWD cars. "If you back off too much, they just slide, so you need to feather the power as you corner..." So I gave it some power and it started to pull itself around the bend. I used the whole arc of the bend, and thank the gods there wasn't a haul truck coming down that side, but I got it back on line. Lesson learned.

For offroading, many offroad vehicles have a system that locks the differentials letting you have all the advantages of open diffs and the traction of welded diffs when you need to be in a loose surface.

[@codymoncrief8478]

Limited slip differentials, when engineered well, are pretty impressive throttle/load-responsive traction aids. I use them primarily in heavy-duty trucks that I use to do mobile service work on machinery. They can have very good street manners, but on rough or muddy terrain, a quick romp on the throttle loads the clutches and gets you in, and then out of, trouble.

[@Ampex196]

Well done for your clear explanations that get the basic principles across in an easy to understand manner. I've only owned one car with an LSD (Ford Capri 2.8 Inj. Special). It was very useful in wet conditions where you could 'feel' it 'clutch up' mid bend. Not quite as helpful in heavy snow/ice conditions. Neverthess, I managed to drive it through a dire winter situation where modern FWD cars were giving up - thereby causing additional mayhem by blocking the road.

[@stevefox3763]

Many years ago a Mk1 MR2 took out my Mk3 Fiesta while it was parked at the roadside outside my house on a main road. The MR2 was doing 60+ Mph when it hit, it scooped up my fiesta with its low nose and my car went up the bonnet and the front edge of the roof, ripping them off while going airbourne and flying for around 120ft. My car was bent up from the rear as well as sideways and also twisted with huge kinks in the roof and the impact force was so great that not a single switch, clock, vent ect remained in the dashboard and it also sent a shock through the car violent enough to break the water pump! The MR2 veered off to the left, smashing through a wall and falling down steep drop off, it was utterly destroyed. The passenger who's side took the bulk of the impact with my car was in a real bad way but ran off down the road pouring blood as he was having an affair with the woman who was driving the car and did not want to be caught with her. Scary thing is that I always sat in my car for around 20mins when I got home but was early home by about 10 mins, had I have got home when I would have normally, I would have been sat in my car when it was hit!

[@jizchimp]

Quaife is great in my book. I got a Quaife sequential for my 06evo mr. The tuning and getting everything to jive with the aftermarket ecu is key. It is tame enough to drive casually but is in its element when literally banging gears. Clutch obviously for starting and stopping but having the spark cut at the perfect time and time duration is key to a solid, smooth but quick engaging shift. I was able to go with a slightly bigger turbo but was also more efficient because I don’t lose boost between shifts. It definitely turned the car into an entirely different animal. I’m still at just over 500awhp for daily but can go up to about 900 turned up. The 500 now feels more like 600 compared to what it was rowing gears. Never out of boost while on it until you let out. So much faster then before. A quality product that in my case at the time it was also the cheapest.

[@GeorgeTsiros]

3:15 : Viewer, please note: "allows two wheels *on the same axle* to rotate with different speeds." Very important bit! A differential is required for two wheels to move at different speeds _only if the two wheels are on the same axle_ . If they are _not_ on the same axle, not only do they not _need_ a differential, they can not even _have_ one! (The moment you connect a differential between two unrelated wheels, they immediatelly acquire a _common axle_ )

Just saw this video today and thanks for the new upload. I think I was the main reason you took your version 1 down and this is correct, but I doubt the Miata-theory. According to a BMW E36 Cup driver (150 hp) they would all weld their open diffs if it's allowed, but it isn't. I was racing e-Karts on the Nürburgring and even those heavy karts corner great with a spool as well as Quads. You just drive so fast that the inner wheels lift off a bit and allow the slip😁 On the other hand there are open diff race-series like Formula BMW, Ford, Vee, Skip Barber, F4 and even the Praga Cup. Not sure if it's and advantage or a mandatory handicap.

[@StagnantMizu]

Open Differential: Functionality: An open differential is the most common type found in most vehicles. It allows the wheels to rotate at different speeds, which is essential for smooth turns. Operation: When one wheel encounters less traction than the other, the open differential sends more power to the wheel with less resistance. While effective for regular driving, it may not provide optimal traction in certain situations, such as off-road or high-performance driving. Welded Differential: Modification: A welded differential is a modification where the gears inside the differential are physically welded together. This eliminates the ability of the wheels to rotate at different speeds. Functionality: The welded differential essentially forces both wheels to rotate at the same speed. While this modification is inexpensive, it can make turning challenging, especially on surfaces with different traction levels for each wheel. Limited-Slip Differential (LSD): Functionality: A limited-slip differential is designed to address some of the limitations of an open differential. It allows some differentiation in wheel speeds but provides more traction than an open diff. Operation: LSD uses various mechanisms to limit the speed difference between the two wheels. There are different types of LSDs, including mechanical LSDs that use gears, viscous LSDs with a fluid coupling, and electronic LSDs that use sensors and actuators for precise control.

[@gtrulez]

Nice video👍🏻 I bought a Quaife helical front lsd for my Nissan Skyline R33 GTR V-spec, simular to your new diff for the MR2. One of the reasons why i went helical is because it doesn't need maintenance wich is exactly what i need, for the front diff is actually located in the oil pan of the engine, and it can't be accessed when the engine is still in the car. So if it needed maintenance the whole engine has to be taken out or the front subframe dropped.🙈 the car is being track driven and will get a brand new 750~800hp RB28DET engine. So in order to improve traction and reduce understeer the front open diff will be replaced with a helical lsd from quaife. I'm really hyped about it, cause the gtr already was a maniac out of corner exits😁 it has a electronic controlled torque split mid diff in the gearbox and a active rear lsd from factory. Also the helical type is much smoother in operation than a clutch type diff, wich was another reason to go for a quaife helical. I cant wait for the next video about diffs! 👍🏻

[@winner200playz3]

one thing that I would like to mention about the downside of a welded diff is that during a corner exit the driven tires are not only accelerating the vehicle but also keeping it from sliding sideways (on a fwd car this will result in understeer and a rwd will result in oversteer). On a welded diff the inner wheel will spin so you also lose that sideways grip keeping your car from spinning out, even though you may have better acceleration. On the lsd the inner wheel will spin less and maintain that sideways grip and keep your car on the road. That loss of sideways grip is also what makes welded diffs good for drifting, you want to lose that sideways grip and get things spinning.

Great explanation You also should notice one more advantage in cornering about natural toque vector difference with lsd diff,much more pivoting the car around rear axle,so lsd is great even for weak engine cars.

Great video and awesome way to demonstrate different diffs

My little half liter Suzuki Carry truck has 4wd and Limited Slip Differential. Love my truck.

Totaly Genius

Hey dude (what's your name anyway?), I'm an automotive teacher and it was always hard to draw a gear type LSD on the board for students to redraw it into their books. The way you assembled it using a Lego is simply genious. You've actually helped me. I just installed a RacingDiffs LSD retrofit kit to my car today (that's why this video caught my attention) and in combination with adjustable x-drive it is simply awesome. And so damn quick it's sometimes hard to keep up with.

Why did seven people dislike this? They wanted a video of fuzzy bunnies, and dammit, there are no fuzzy bunnies in this video?

brilliant explanation of all three diffs...👏👏

[@alexandrhrouz666]

Cops stared at me a little bit weird when i talked about LSD being expensive on local market

In beamng drive, the welded diff is the best for drag racing. You get 1 to 2 car lengths on launch easily over other diffs if you set up the gears and grip correctly

Well done. I with I could give this video ten likes. Very good explanations on each type. Thank you for entertaining and sharing.
