Eaton Truetrac are designed for medium duty 2WD and 4WD applications. They work well in the front and rear, and are so smooth that there is little or no hint of resistance in the steering wheel when used in front drive steering axles. Like the Gleason Torsen, the Eaton Truetrac does not bang or clunk, has no clutch chatter, does not wear out like clutch type positractions, does not need limited slip additive, and needs no preload or clearance adjustments.

Just replaced the stock clutch based LSD in my Jeep with this unit. What a difference in traction. Instant lockup, feels like there's a locker back there and it handles the rain with no weird handling. Tested it out by putting one wheel on pavement and the other in dirt and stomped on it. Jeep took off like I was on pavement with nearly no slip on the dirt side wheel. Amazing unit, quiet too.
@SummitRacing12 жыл бұрын
They use worm wheel gears that work on the same principle as a worm gear. When the unit is loaded, the worm wheels are forced away from each other and against the case. They develop locking torque by the light friction between the worm wheels and the case. This light friction is multiplied by the ratio of the worm wheel which depends on the size of the worm wheel relative to the size of the side gear.

When I had my 01 2wd Yukon with this installed I could drive through most things. Control was superb, would even drive in deep mud. Could get out at idle speeds and both tires would spin in place, hop back in and give throttle. Would push right right out of low traction situations. Also handled the abuse of drifting with ease.

When used in situations like rocky trails where one wheel gets off the ground, the unit will not lock up 100%. Light application of the brakes will help the differential engage more transferring power to the tire that is still on the ground. For extreme situations where the vehicle will have one wheel in the air often a locking differential provides better power transfer to the wheel on the ground.

To my understanding, new vehicles such as the 2024 Sierra, automatically actively engage the brakes in stock form to provide traction to the opposing wheel. Are these True-tracs suitable for newer vehicles that have this feature? Are there any downsides to applying this the the rear of my Sierra?

@SummitRacing12 жыл бұрын
The manufacturer can change the amount of torque biasing or lockup by simply changing the diameter of the gears, or the pitch and spiral of the teeth. A larger difference in the size for the worm wheels and side gears (smaller worm wheels and larger side gears) will increase the lockup force. Increasing the pitch and spiral of the teeth will also increase the lockup forces.
@SummitRacing12 жыл бұрын
Like everything, there is a limit as to how much lockup force is reasonable. Making the unit too "aggressive" will cause tire scrub during everyday driving and will cause the unit to wear out too quickly. All of the feedback that I have received from customers indicates that the unit works very well for mud and snow, while going unnoticed during every day driving.

After the 3rd time breaking the 10 bolt i said screw it and paid the 3 grand. All i said was i wanted the latest and greatest and they suggested and True Trac instead of a clutch pack limited slip differential. I love it. It even has a slight hum to let you know it's tough and ready for abuse. The only problem ive had with my 12 bolt is a right side axle seal leak. So i give a Tru Trac a 10 out of 10.

@gasripper2 That is when you press the brakes to get some traction on both wheels. I know it sounds weird but that's what they teach you in the army to do and it works. The explanation is simple when you brake the light wheel slows down and it forces the locked one to go.

@jondoe54828 жыл бұрын
From looking at diagrams and pictures of this differential, I have concluded that the torque-biasing works due to the helical nature of the gears. As the input torque increases, the "sun and planetary" gears are forced into the walls of the unit, creating friction and turning the wheel. Whatever wheel has more resistance to movement (taction), therfore receives more horizontal force, resulting in increased friction on the gears, thus the torque bias functions.

@deezynar it's on the older Hummer and military HUMVEE driving manuals somewhere that if you apply the brakes to the spinning tire, it will force some of the torque to transfer to the other side. This is the same thing a limited slip will do, take some of that wasted torque and transfer it to the tire with more grip by providing a certain amount of built-in "braking" action for each axle that simulates traction.
@SummitRacing12 жыл бұрын
Only then will the torque transfer occur - when it is needed. As with an open differential, the TrueTrac side (or spider) gears are interconnected by pinion gears, which allow one wheel to slow down or speed up as required. TrueTrac gears have spiral teeth and the pinions are mounted in pockets in the case.
@SummitRacing12 жыл бұрын
Truetrac differentials are unique in that they increase traction but do not affect steering or wear out prematurely; these problems are common with limited-slip differentials that use clutch plates and springs. A TrueTrac performs like a conventional (open) differential, until there is a loss of traction.

The one in my 2010 Chevy Camaro SS manual coupe, came with a super noisy rear diff at around ~19k miles, despite me changing the gear oil and seeing that it appeared to be decently clean and barely having metallic particles. Maybe the prior owner did the rear diff gear oil change and didn’t use the right weight of gear oil, or maybe forgot to get a formula that included limited slip additive? Cold starts when I first got the car, would have my car turning more than a 1/4 way, to start groaning and clunking. It scared me so much, I’m an idiot for even getting the car. I did my first gear oil change (simple drain and fill) with a semi-synthetic (?) Lucas GL-5 80w-90 gear oil. It supposedly contained “additives”, but nothing that suggested LIMITED SLIP specific additives. It probably meant friction modifiers or some other stuff. Either way, it surprisingly cleared up most of the noise, but was still groaning half as bad during cold starts. The diff would be fine and quiet after reaching optimal temps, which it didn’t before, which also prompted me to believe that someone may have also used a super heavy weight, such as 75w-140. But weren’t these things able to warm up decently? On the dealership test drive, I drove on the freeway for a solid 15-20 minutes, and was also doing a lot of turns and full steering locks around the dealership area during the test drive. Regardless, I stuck to 75w-90 gear oil, but decided to go for a Mobil1 semi-synthetic(?) GL-5 gear oil that contained LS additive already added(‘High Performance’ was the model of the gear oil, I believe). This was my 2nd gear oil change since getting the car and I still didn’t see much metal particles on the magnetic drain and fill plugs for the rear axle differential, but flushing the gear oil probably helped some, as it got to maybe 30-35% as loud as when I got the car. I finally decided to flush it for the final time until this day, which I used the infamous Royal Purple Max Gear 75w-90 that everyone in the Camaro5 community recommends. It comes with LS additive, as well as being a ‘Synchromesh’ specific GL-4+ (GL-4/5) rating, which was safe for yellow metals, such as brass (used for most gearbox synchronizers). Now, this finally got the rear diff to shut up and stay quiet up to a good 10-15% as loud as when I first got the car. However, really cold days (50 F or lower), will have the rear diff groaning just a bit longer (takes longer to warm up probably), but not any more louder! I’m pretty okay now, and dodged a bullet with trying to hassle Chevy to go through the process of trying to work with my rear diff issues, which they did NOT try to address AT ALL whatsoever (that’s a WHOLE other crock of beans…). I may or may not actually try some of the OEM AC Delco gear oil and separate LS additive formula, to see how well it stands up to the aftermarket support products. But as of right now, I don’t plan on adding EXTRA LS additive, like most ppl do to quiet their diffs down, bc I fear of adding too much and having excessive slip that might cause ‘one-wheelers’ with literal straight line driving!!

@MudBarf I think, basically, that the pinion gears get "locked" in their cups in the carrier, until in a turn the outside wheel over-runs the inner, causing its associated pinion gears to become unloaded and allowed to turn. Probably I'm wrong, but it seems similar to a standard open differential except that under load both axles are locked together unless in a turn.

This is a *TORSEN DIFFERENTIAL*. They're basically an *OPEN DIFF* when one wheel has 0% traction (off the ground, slipping on ice, or doing a "burnout" with one tire), so they aren't all that good for OFFROAD or RACING (because you'll lose power to BOTH wheels if one completely slips), but they're awesome for bigger vehicles that know you'll always have SOME grip at least. *Plus they're smooth, bulletproof, and quiet.*

Ok, this is really bothering me. I've watched this 3 times. I understand the gear meshes, I understand how it allows differentiation through the gear movement, and I even understand (pretty sure) what they're trying to explain with the force diagram. What I still don't understand is how any of that gear meshing provides any resistance to the differentiation process. Is it basically by utilizing the friction created by jamming the pinion gears into the side of the pockets? (Fc) in the diagram?
@deezynar14 жыл бұрын
@kingkruel123 Actual opposite rotation wouldn't happen in a car, the video is exagerated. This diff won't allow the 2 wheels to rotate at different rates without both of them having traction with the ground. If one wheel loses traction, the slipping wheel will rotate at the same rate as the wheel w/ traction because w/ out traction, it can't rotate its worm gear to let the worm wheel rotate, thereby keeping both axles "locked".

are these units going to perform as well for initial straight line grip as a conventional cone type lsd?

Oh...I think i thought about it backwards... Instead of thinking about it from the perspective of the tire that slips, if you look at it from the perspective of the tire with traction: The traction wheel applies resistance to the slip wheel to make it refrain from spinning..that is to say the system as a whole attempts to keep the slipping wheel going the same speed as the traction wheel...that makes a lot more sense...but I feel like you're losing drivetrain power in the resistance force.

So how does this get any posi action? By cranking the planets into the housing walls? Seems like it's going to rip itself up quick. It's an open diff as far as I can tell unless the friction of the planets into the housing is enough to stop them from turning.

is this locker puting in a front differential and is it worth buying for hardcore off roading how about if your going up a hill or in the mud and turning the front wheels would it still have a both tires spining at the same time ???

I know entirely that im nitpicking, but shouldnt the answer be more concerned with torque, than power? 400 hp from an na v8 is a different ball game than 400 hp from a turbo charged diesel engine. Just saying. Great product, LOVE this video. Its fascinating to see whats actually going on inside.

There idea is probably off of power band of engine. Diesels make horse power low to high steady. But torque is made low to mid because they are low rpm naturally. I would have the same question.

importsstillsuck, Anymore power than that; you should consider a Detroit locker differential.

the Nismo Wavetrac and True Track are much alike, but the Nismo Wavetrac has 12 pinion gears while the True Track has only 6, it seems to me that the Wavetrac would be much stronger

I just had one installed and it’s doing a lot of clicking on hard turns. Do ya think something may be wrong with the unit or the gear setup? I also just put a cheap STP 80-90 gear oil for the break in, should I put something different?

did you get it figured out? I am getting one installed in my truck later this month once the differential shop can get my truck in on the 22nd.

@@Long-nd8bq yes, I figured it out. It’s not the Detroit true track. It was the cheap gear oil. All I did was change to Lucas 7590 gear oil and it solve that problem. It was so weird but when I drained the cheap STP fluid it came out like water. It was so thin. I think the clutches/worm gears were binding because of lack of lubrication.

does anyone know where to get this type or style of diff for a 1987 Suzuki samurai (sj413) . I can't find any models for a samurai on the eaton website, and I hear rumors about the Russian made ones but I only see listings for like new trackers and vitaras, I found a brazil made torsen diff but the website doesn't work right and I can't see how to buy one, or anything.
