Does the 2019 Ranger have a LSD? An Investigation

[kep]

I remember a video early on that explained somewhat the algorithm used with the open diff. Basically it uses the speed sensors and braking on the wheel without traction to send torque to the other wheel. After 3 F150s and a mustang that all eventually had issues with the limited slip, I am eager to see how well this works? I don't plan on doing much off-roading, so I hope I don't regret not ordering the locker. I needed/wanted 4x4, heated leather seats, and the push button start, so that put me in a Lariat and my pocket book limited me as to what options to choose.

you're gonna love it, after 2 weeks in the snow it has proven I made the right choice in not adding the locker. This truck is a beast in the snow. this story had a lot to do with finially deciding I could do without the locker.

That's good to hear. I am very eager to get my truck and try it out, but by the time it's delivered, I may need to wait until next winter to play around in the snow.

If the axle is NOT a limited slip axle, that's odd. Reason it's odd is because it's the same axle used in the Jeep Wrangler JL where they ALL have limited slip differentials, unless you select the Rubicon trim level which gives you a different version of the axle which is wider and has an e-locker installed. But, there is no such thing as a Dana M220 rear axle with an open differential.

I believe the Chevrolet Colorado also uses this axle and has limited slip capability.

So, if Ford is selling them without limited slip, then it seems it's a decision they are making purposefully for some odd reason.

Seen as I stepped in this I will go to dealer and find out.

OK here it is. It's open also he said you can't have clutches because it wouldn't lock when locked this make's sense. I said how do we prove that he said no problem they had the owner of the dealer ships brand new lariat 2x2 they just got yesterday, and locked it and when driven corners wheels chattered because you got it no LS. And yes they don't show rebuild parts for the diff. because there's nothing to rebuild inside the diff. See parts diagram I posted. Here's more. www.Dana.com/light-vehicles/products/drivelineaxles#search when there select jump to then differential systems. Now read what it says. Doesn't seem to work but i if you type it in on Google and follow the directions it will. Iam sure someone else who has computer skills thats better than a old man on a free consumer cellular phone can fix.

IMO a traditional clutch style LS is way over hyped. The wheel with less traction will always spin. If both wheels are on equal traction, pavement, ice etc and equal weight is distributed on the wheels, both should spin. A torque sensing LS like the Detroit True Trac sends power to the wheel with the most traction after the wheel with less starts to lose traction. I would want a locker if I was buying a 2wd (if their available?) just for emergency situations, backing into a boat launch etc. However, with modern traction control all vehicles essentially have added traction via electronics.

Locking rear axle is available on all 4x2 and 4x4 Rangers.

As RD said 2wd option for e lock. Can confirm LS sucks on snow and ice as all it does is parallel park you without having to turn the steering wheel.

Limited Slip on my '02 Ranger, and my Jeep do NOT suck on snow or Ice. I live in Buffalo (and Colorado for 30 years before that) and have extensive experience.

So I had posted some pictures in a different thread of what the tire tracks look like with a brake assisted wheel spin. They both turn at least some. I then jacked up the truck (and forgot to take it out of park) and when turning the left wheel, the right wheel spins opposite. I'm not sure if that's a relevant test since I left it in park, but even if wide open, the brake "LSD" is working fine. I had the same feature on the Focus ST I had, and it was completely adequate for a vehicle putting almost 300HP to the front wheels, so it should be OK for the truck.

I have the locking rear diff, but it was disengaged.

You want the transmission in park so the drive shaft does not turn. One wheel going in the opposite direction is exactly right for a standard [open] differential.

Thanks Geoff, I always forget which way to do it. It's open then, but the brakes do a pretty good job of being an LSD. Can't wait to try and get brake pads for this when it's got 30K on it

Need to mark this thread solved, and do the humane thing and put it to sleep.

I think your link is broke. Is this what you were talking about?

https://social.ford.com/en_US/story/vehicle-type/truck/first-look-at-the-2019-ford-ranger.html

"Power is distributed through a Dana® limited-slip differential on both 2WD and 4WD models."

I noticed in the same article it states "Driver and passengers can charge devices via available 400-watt, 110-volt AC power outlets and USB ports." but in the actual 2019 Ford Ranger Owners Manual it states "The power outlet temporarily turns off power when in fault mode if the device exceeds the 150 watt limit." So is the article right and it's a 400w outlet or is the owners manual correct at 150w?

The f 150 gas a 400 watt inverter .. the put it under the rear passenger seat ... it’s big .. ranger is 150 watts .. and that’s it .. I have both trucks

Yes but that's old news both are open.

Not only that Limited Slip is not gas mileage friendly. Every time you round a corner those clutch discs have to move [slip] and that takes energy which eats a tad more gas. Adds up after a while.

Four wheel drive is even less gas mileage friendly, but they still offer it.
Towing is greatly enhanced with LS and tire wear is greatly reduced.
I'm not sure what good traction control will do as a substitute, if any.
I am resigned to getting my truck without LS, at least until Ford Motorsport or Dana offers one aftermarket. That's what I had to do with my present Ranger.
