(PART TWO) kzfaq.info/get/bejne/md6VoMaAz52deIk.html

That's not limited slip in the front. That's the traction control locking down the passenger side brake, causing the driver side to pull.

Finally a definitive video of how Torsen and Terrain mode works. One of the most basic but valuable videos I have seen on this subject. Even better than any documentation I have found in that this is proof in front of the eyes. THANKS.

Probably one of the most helpful informative videos on the web right now regarding the tremor package. Thank you!

Great demonstration! Hats off to you for understanding how the diffs work. FYI, it my OPINION after watching your video that the Tremors front limited slip never engaged in your video. I *believe* what you experienced was computer controlled brake applications to individual wheels. I believe this because it did not “engaged” (work) until you put it in snow/sand moved which is computed related. Limited slips are mechanical, no computers needed.

You can just add your own electric locker or Ox locker if need it to lock in when you want it. I installed an Ox locker on the front of my super duty

All you had to do was hit the brakes when you were in normal 4x4 mode and you would have had the same results. It is a Torsen limited slip differential. The electronic aides apply the brake for you is all. The Raptor is the same. When I had mine, I would have had the rear locker engaged in that situation, but in situations where ground gave way, or snowy conditions when I didn’t want my rear locker engaged, this was all I did, touch the brake with the necessary force to engage the limited slip. Away you go. Sometimes mistake the Eaton automatic rear locker in the GM products (option code G80) as limited slip. It is not. When it engages the axels are locked. It doesn’t disengage until the forces are equalized and there is not enough force applied to keep the locker engaged. It actually forces you to be smoother on the throttle to get the most out of it. I see so many people give enough throttle to almost get going, then they let off and on that over and over again. It’s painful to watch.some of the guys on TFL used to do that. Tommy was terrible but a few of us explained to him the need to be smoother with the throttle and he has improved a lot! Enough to accept that the G80 is a decent rear locker! Most people prefer to engage them when they want it and that’s why the electronic engagement is so very popular. I prefer it as well, but learned to off-road with trucks equipped with the G80 option code. The tremors are nice, but too big for great off-roading. You have the exact right philosophy on why you own the truck and I agree with you totally!! I had a Raptor to use off-road in some private areas myself and a couple of other guys own. We have our own 6600 acre playground in the foothills and mountains. I took the Raptor onto some very serious trials the day I got it!! It was a base Raptor I got when they still had discounts on them it was the SuperCab. I already miss it. I sold it in the winter!! Hahaha. I have a 21 F150 Hybrid with a mild lift and better tires with the FX4 package but a fully open differential. The trail options. Like mud and snow, do help the front end though. Enjoy your truck!! It looks great!

I just watched part two now I need to come and watch part one.. thanks for posting.

I got my gas Tremor 2 days ago. Great video and explanation. Thanks.

Thanks for doing these tests.

Thank you for this video, it answered a few questions of mine. Now I am positive that a elocker is the only way to go for the front diff.

Dude! AWESOME video!! MUCH NEEDED THX!

GREAT VIDEO!!! I just ordered a 2022 F350 Lariat 7.3L - Tremor Package - Ultimate Package ($570 DISCOUNT on Tremor Package) - Black Appearance Package ($570 DISCOUNT on Tremor Package).....including the Warn winch...and every other Option except Adaptive Steering and Pro Trailer Backup Assist (SISSY BOY KNOB on the dash). Wanted the Ultimate Trailer Tow Camera System...but no longer available as a stand alone Option like it was in 2019. Ford packaged the extra 3 cameras with the SISSY BOY KNOB. The side and front cameras would have been good to have with the Tremor Package. Might check the salvage yards in 3 to 5 years for mirrors and front Ford oval with the cameras and other parts and add to the truck. A good friend ordered an almost identical truck on the same day from the same dealer. That truck has all the same Packages and Options except it has the new Sport Appearance Package...so, the LED lights and Tough Bed spray in liner had to be added. We got $4875 off MSRP on each truck.....not easy to do as most dealers are selling Tremors at full MSRP.

Beautiful truck

For what it's worth, most gear-based limited slip diffs act like an open diff when you have one wheel completely unloaded, like you did in the video. When both wheels have some traction, you can actually feel it working. When we had the snowfall here in Texas a little over a month ago, I have one section of my driveway that's about a 12% grade and very steep. I was able to go up it just fine in 4Hi and could actually feel the steering wheel slightly "torquing" back and forth while I cruised up the steep part of my driveway and one wheel would slightly slip and it would transfer power to the other side. It works well, but won't do much for the scenario you did here. This scenario is going to rely 100% on either the computer grabbing brakes on one wheel to simulate having traction on the unloaded side, or you're going to need that rear locker. Either way, the truck has lots of options to try to get yourself out of any trouble you may have gotten yourself into.

That's not limited slip. That's traction control applying breaks to spinning wheels.

Nice test. Thanks for the info

Very interesting. I wish Ford offered the Tremor package in the shorter SuperCab. I'd guess the front limited slip system is a computer controlled brake actuated limited slip system. It's effective, robust and inexpensive. A Torsen would also work but it's a somewhat complicated package of spur, gear and "worm" gears that might have torque limitations on a vehicle as heavy as a F250. It's also somewhat expensive. A front electrically operated locker encounters binding when turning risking damage to the driveline and making it difficult to steer. They can be programmed to disengage under certain situations but then it's essentially an open differential. Thanks for the review

I really like this truck. I want an F250 Tremor. I think it is an attractive looking rig and I love its capabilities. It’s not cheap and I’m not made out of money so I really need to think about if I want to spend the money on this. If I can manage it I would like to own this truck and have a camper trailer for road trips, camping, etc.

Nice vid bro!

I might have commented this on your other video but if not… Dana developed a traklok LSD specific to the super duty trucks. It’s a 100% clutch based LSD and not a Torsen style like in the F-150 tremor and raptor. The little bit I’ve managed to read about it, it would sound like it was chosen over the Torsen because of strength. My F-350 Tremor is supposed to arrive at the dealer tomorrow. I ordered it back in April so I’m pretty excited!

If you want it to lock up, you'll need to manually ride the brake and gas together. It should lock solid then. My F-150 Torsen does.

Good video. Subbed.

Very good video, nice demonstration, I don't think you are going to go that many more places with the power wagon if any more and you lose towing and hauling capabilities. I have taken mine in some severe spots and it is a beast to say the least.

I'd have to agree with you. As much as I'd like to have a mechanical lock the truck is designed for 99% of it's use.

Great point, this truck will do more than what 95% of its owners will throw at it. If you want to hard-core off road, wait for a bronco!

Niiiice. Ram guy here. Want a power wagon but prefer 7.3 over 6.4 for towing long tt like yours. Power wagon has front lockers, but i think the lsd on tremor will work just fine. My 17 ram 3500 would get stuck very easy in light snow. I refuse to own another 4wd that sucks in snow. All 4wd is not created equal. F350 tremor is now top of my list

Seems to still be a lot of debate on the "LSD" technology in use with not a lot of sources. According to an article on Hagerty about the Superduty Tremor it uses a Dana limited slip. Looking that up it seems to be a Electronic Limited Slip Differential (ELSD). KZfaq "Electronic Limited Slip Differential technology for light vehicles" and the first video will give light details on how it works. That description looks like it fits the behaviors we see in these 2 videos. Also stated in the Hagerty article "In off-road driving modes, one front brake is automatically applied to a wheel in the air to direct torque to the opposite side". This is still conjecture, not facts, but the shoe fits. Seems like it would be easy enough to determine if the Dana system is used by looking at the front axle. I do think we can all agree that the behavior seen here is lackluster compared to what we would like, whatever they want to call it.

I believe it’s a torsion style. It won’t lock with massively different traction levels. (One wheel on ice, and the other on pavement) They can be helped with some brake engagement. They also are somewhat speed sensitive. They work really good most of the time, but they are not a replacement for an actual electric locker. Agree, rear locker and front limited slip works for 99.9% of people and uses.

Great video thanks

I subscribed and liked to help you out...

Awesome!

Nice video, subbed. Where'd you get those 7.3 emblems on the side? Nice touch.

If that was a power wagon all 4 tires would be touching the ground. And let’s not forget you would get locking front and locking rear with swaybar disconnect and a very nice warn winch.

My tremor is getting an Eaton up front for sure.

Great video, I just ordered a tremor and was going to remove the front axel torsen diff. but this appears to prove its still lock when needed. would you get it like this again if you can do it all over again? I feel locking is better even though it sort of takes over your steering wheel a bit at least you won't get stuck.

Appreciate the video. Are those 4 small aftermarket lights in your front grill? Love the look. Curious as to where you purchased them.

Thanks for this vid 👍🏻👍🏻 sub

What an amazing truck!!! :) My husband has been looking at an F250 for a bit, but prices here in the DFW area have gone absolutely nuts. Some dealers are asking way over MSRP for them, sometimes more than 50% more. Same with the HD version of the GMC 2500 AT4.

The front hubs will lock manually. I pulled an rv through a giant football field sized mud hole with my Tremor. Locked the rear diff and front hubs and it was as if I wasn’t even towing anything

Hmmm. I have a 2019 F250 which has the electronic locking rear differential. It works good in snow.

In the deep snow and ice mode, that's your traction control engaging the breaks on the front right wheel and rear left wheel sending torque to the wheels with them most resistance or traction as you like to say it. It's not a locker or even the differential at play.

Nice demonstration, I assumed it was a clutch type lsd but seeing it didn’t engage till a certain setting was used... so electronic?

Hey guys, you left a lot of comments with some really good observations and questions that I would like to answer. I plan on making a follow up video tomorrow and hopefully answer everyone's questions. Please subscribe so you can catch all my videos!

OMG, I cannot wait for mine. What a sweet truck. Is yours star white or Oxford white? I choose Oxford white for mine.

Did you just try tapping the brakes to get the front to "lock up"? The truck traction control is probably just braking the front right tire to get torque to the left front. It may not even need a LSD to get torque to the wheel with traction. Nevermind, just saw part 2.

That's pretty interesting, I wonder if the front diff asks for limited slip additive during a fluid change, that will usually tell if it actually is a lsd. It seems like maybe it's a brake torque system since drive modes affect it. However ford makes it seem like a true lsd

How loud are those tremor tires on the paved road for real? Also next time you get in that position while the wheel is spinning put slight pressure on the brake and the front will engage faster. It basically fools the diff and engages both sides.

I have not heard any details or specifications on the Limited Slip in the front Dana 60 differential. If it is the standard factory OEM style limited slip......those wear out and do not last long. I could be wrong...but what I have read...the BEST is the Detroit TrueTrac with the HELICAL gears....aka, "Worm Differential". Lots of guys like these both front and rear instead of e-Lockers or air lockers. The Detroit TrueTrac AND the DynaTrac Heavy Duty Free Spin Front Hubs - DynaLoc will be future upgrades to the Dana 60. The DynaLoc hubs are heavy duty.....strong "old school" technology with serviceable Timken bearings.....with the "Free and Lock" settings. The Ford OEM hubs are weak...have throw away "unit bearings".....with "Auto and Lock" settings...and uses a solenoid and pneumatic system (something else to break down) to engage the hubs when the knob on the dash is selected from 2H to 4 H or 4L. Granted, the DynaLoc hubs will require getting out of the truck and turning the hubs from Free to Lock before going off road. However, I would rather have components and parts that are reliable and durable.....

It would be interesting to know definitively whether its a gear/torsen or clutch style front limited slip diff. I've been searching online for 1.5 years for the answer and a lot of armchair pros say its one or the other but none know for sure but are just talking out of their butt. Be nice to hear from a FORD Tech who has had a front cover off of one to know for sure.

Why don't you manual lock the front axle? It's in the center hub of your front wheels

Not the limited slip... its the traction control. A mechanical limited slip, whether torsen, friction, gears etc will not be able to have variable slip by a knob in the cab, they are mechanical devices. The front LSD in your truck is mild but will help the most in snow/ice to give you power- on steering response when it's slick.

In deep snow and mud terrain it automatically locks the rear differential.

If it’s a “mechanical only” limited slip locker. A drive mode won’t change it. It would have to be a electrically actuated limited slip. The rear is a electrically locked carrier.

That’s the traction control for sure. A mechanical diff wouldn’t have cared what mode the traction control system was in. It’s a completely mechanical process.

I woulda thought the rock crawl mode woulda engaged the front locker 🤷🏼‍♂️

Cool video! Thanks for sharing. Is it true that in AZ, its best to go with the F250 instead of the 350 due to DOT regs? Make a video detailing how all that works.

man, amazing truck but do the led front lights not come on the tremor?

It might have engaged if you hit the brake and some gas

Suspect that was traction control kicking in.

That’s all I would need and I can get a diesel or the gas would probably be no where near as bad on fuel as the dodge.

Holler

I noticed the leaf springs are different than my 21 F250, non tremor. My leaf spring setup from factory are 3 total, two .5” and one 1”. Can you post a picture of your leaf springs?

Why didn't they just go with a front manual locker?

Then what’s the point of having rock craw if it’s not going to lock in the front dif

How is this truck as a daily driver?

Are you sure your truck even has the torsen diff? There are F150 Tremor videos that have the torsen diff and it’s night and day.

Man that wasn’t even trying to move. Thought it was supposed to be a Torsen lsd. It should have tried harder to turn both tires. The one setting that worked probably caused a brake locking function. Not sure why rock mode would do that though.

Why can't you just get out and manually lock the front hubs by turning the dial in the center of the hubs?

there's a locking hub on the front wheel where you can manually lock them together, just turn it clockwise to lock them and counter clockwise to put them on auto

Could you hook up 15k and tow up some mountains? I have a 42 foot fifth wheel and have been debating trading in my diesel for a F350 Tremor 7.3L gas with the 4.30 rear end.

Like+ from Saudi Arabia.. + subscribe.. + share.. What else?!

I see that powder coat coming off on the passenger wheel lol

glad i didn’t get the tremor now i wanted the front limited slip diff and it’s useless. That was all traction control grabbing the brake of the front spinning wheel and sending power the the wheel with traction. called simulated limited slip. Disappointed this guy didn’t know that. It was extremely obvious that the front differential doesn’t work well at all

My God! Turn the intro sound down!!!!! (Thanks)

I would rather just have a true locker up front. LSD is too slow.

I dont think the Limited slip makes any difference what brand it is. When you switch drive modes the ABS is why it moves forward. Jeep cherokee does the same thing without the infamous Ford Torsen. Jeep Vari lock. Better than an open diff alone but far short of a locker. Traction control system. LSD do not lock ever. Your switching the torque bias to the opposite wheel.

Your LSD isn't working. Or this isn't a a true limited slip. Maybe, this is something new that is only engaged when actuated by the computer when drive modes are changed. My raptors front torsion LSD is always ready to push the lock down when in four wheel drive

Performance in “rock crawl” is extremely underwhelming, disappointing actually. Rock crawl should have the least wheel spin when hanging a tire

You spent 80k on a non disease super duty ??? At least that is what you said. That can’t be the cost of the truck itself, you must of included the cost everything else into it.

these trucks are work horses not show horses... if your looking to play off road I would say an HD PICKUP is not the vehicle of choice.
