Adding diff lock and Terrain management button

[koya31]

Hello folks,

I just bought the used 2020 ranger lariat with 8500 miles. However, I hit the car due to my truck slipped on the icy road while I was driving on the down hill of parking garage. So I was thinking that I need to get a diff lock and TM. But I'm stationed in Korea so it's really hard to install the diff lock but I can do TM by my self. So my questions are: 1. Does Terrain management sys helps when drives on the icy road? 2. When I go back to homeland, can I go to ford then ask for adding diff lock on my truck? And how much is it cost for?
Thank you!

There is one more question: how about to install trail control? Can ford maintenance do it? If so, how much is it cost?

1. south Korea huh? thanks for your service. I have a pot of kimchi stew on the stove right now.
2. do you have much experience driving in snow? locking diff makes it worse
3. search the forum. others have tried adding factory locking diff and it costs as much as ARB setup

Ford will not do it as it requires Forscan. As for trail control it has yet to be figured out and probably won't happen. As for terrain management it has been done before. Will it help enough with ive? Most likely not. Good snow tires with studs would most likely be best for that. As for the locker. Chances are it will work, you just have to swaps the entire rear end and add the button(I have the button if interested).

You just need better tires. Run real winter tires in winter (like a Bridgestone Blizzak or Nokian Hakka), then a good 3PMSF All Terrain in summer, and your truck will actually have adequate grip.

While rear diff locks can help control speeds on really technical downhills, they must first have adequate tire grip. And hill descent control would be way, way more helpful.

I added the terrain management to my Ranger Lariat. It's just a button in the middle of the 2WH-4WL-4WH nob. I can't remember how much it cost but I could have done it myself but had my Ford dealer do it. I believe they had to enable it in Forscan also. I used it in the snow we had and seemed to work great. Modes are Sand, Snow, Grass/Mud/Gravel I think??? Others here can chime in on that.

I drive through ice and snow for 5 months out of the year.

Never once have I NEEDED a locking diff nor any gimmicky terrain modes to get anywhere.

It sounds like driving in slippery conditions is foreign to you. My advice would be to get some snow tires and just be more cautious. Practice makes perfect they say... next time you get some snow... find an empty parking lot somewhere and have some fun. I've done this every time it's snowed since before I even had a driver's license.

My mother would always scoff and call me foolish for wanting to dip into an empty lot to do donuts/drifts/whatever when it was snowing... I told her that apart from being good clean fun that'll keep me off drugs it was teaching me valuable skills about vehicle control. She'd scoff some more and call me foolish.


Well.....

One night about 3-4 years ago, she flipped her truck onto its lid in a ditch on her way home from work.... because it was snowing, the back end started to come around on her, and she had/has ZERO CONCEPT about counter steering.

I asked her WHERE it happened once I saw her, she told me, and I immideately "told her" HOW it happened. She seemed surprised that I was 100% correct.

Incredibly smug I told her... nobody knows how to correct a vehicle from a situation they've never been in. If you would of been FOOLISH like me... correcting that vehicle would of been a near instant, instinctual, 2nd nature type of action.


Definitely the most validating I TOLD YOU SO I've ever delivered.

that's how I taught the wife how to drive in snow. so far she hasn't wrecked in 13 years

Take the time to learn how to make the most of the diff and the terrain modes. Far from gimmicks, they're extraordinarily effective.

one of the best things my father ever taught me was to do this in an empty parking lot at the beginning of every winter to refamiliarize myself with how my vehicle of choice handled when it got to sliding.

as a result, the only time I've ever actually hit anyone from sliding on the roads, it was so soft, it didn't even leave a scuff mark on the bumpers. I've never hit anything hard enough to cause damage to either vehicle.

and I've never needed terrain management. electronic doo-dads. sure, the doo-dads work as advertised, but they don't substitute for knowing how to drive in the first place. TM won't stop you from hitting someone if you're driving too fast in snowy/icy conditions or if your tires are trash.

While the terrain modes can be a little gimmicky, they do seem to work.

Sand mode w/locker on and AdvanceTrac off is a hoot in an open snowy lot.

But for the OP I'd second the salesman above. Tires, especially if ice is common, and experience are your best bet.

I believe the addition of the Terrain Management (TM) knob will run you around $115 for the part. Assuming your a DIY'r and Installing it youself. You will also need to enable it through FORScan as mentioned above. I understand that it's an easy, staright forward install, but I really dont know all of the benefits of the TM option, but It's probably safe to say, that "stopping" isn't one of them.. Having a firm feeling of your road conditions, a cushion between you and those in front of you, a good comfort lever of your and your vehicles abilities, and the proper tires are all key, to be sure.

Down hill on ice is a tricky scenario that TM will not help you with. Snow tires will help, plus use engine braking to stay off the brakes. Tow/haul mode will give you better engine braking and/or use the +/- button to drop and hold a lower gear.

I'm too poor for that 'gucci' stuff, only gots myself an XL.

The vast majority of the solid parts of our planet were explored using vehicles that didn't even have fuel injection.. TM isn't necessary in the least.

Terrain management is just another one of modern life's little features that's making its people 'soft'. I'd rather make it over/through something 'like a man' than have to cheat.. I want challenge.. I wanna feel accomplished.. if I get stuck? Just part of the fun.

I am the outlier here. 2 of my last 3 trucks had a lock rite locker. Lunch box style. I loved it in the ice and snow. One was 2wd so it was a must. But you have to know how to handle it or the ass end will be pointed the wrong way before you can hit the ejector seat button. I have been known to be a touch crazy, or to put it softer less than sane.
