4L on dry surface

[kolev]

Hello everyone,

I'm wondering how easy it is to damage the gearbox if using 4L on a dry surface. What is your opinion?

I'd ask the question, why? Only put it in 4L when needed.

I drove like that in the parking lot.

It shouldn't have caused any damage if you just went forward and backward without turning the steering wheel.

Thank you, @NASSTY.

The issue is not only in turning, but in any vehicle it is impossible to have both axle speeds exactly the same even driving in a straight line so eventually things will bind up. Usually this just results in tire slippage and increased wear on the 4WD parts due to the increased resistance of the hard surface, but in some cases stuff can break.

I don't know exactly how the new Ranger 4WD and other makes work though, it could be so computerized that it senses the differences and uses traction control or other electronic controls to compensate. Best not to find out though.

It isn’t about “dry” or not dry, it is about tire slippage. Driving on dry loose surfaces is fine, or on wet high traction surfaces. You didn’t hurt anything, just remember that those tires have to be able to slide a little in 4L or 4H.

Find a gravel parking lot or empty dirt lot and drive around for a while with the windows down, you will hear and feel this stuff happening. You need to research when and when not to use the different modes. The Raptors have a 4A mode (and have a clutch in the transfer case to allow a little slippage) which is safer on rainy streets (it is one reason I chose mine).

I drove like that in the parking lot, not knowing it was bad for the car. Now I'm wondering if it could have damaged the gearbox.

You should be fine.

Hello everyone,

I'm new to off-road cars. I'm wondering how easy it is to damage the gearbox if using 4L on a dry surface. For example, if I engage 4L mode on a perfectly flat and dry surface, and drive 50 meters forward and backward, several times, without turning the steering wheel, could this damage the transmission? I suppose that in theory no, but the nuance is in the tires, since the contact patch on the front ones is larger due to the weight of the engine, which means that the rotation of the wheels will still be uneven. What is your opinion?

Dear God, you city slicks buying trucks to pose in never cease to amaze me. No, your truck will be perfectly fine. If you go doing that a lot it will become a problem but one time in a parking lot absolutely not.

Thanks everyone for the replies.

Thanks everyone for the replies. Right after that drive, I noticed a slight vibration or jerking when shifting gears in usual driving modes 2H/4A. Perhaps it was there before and I just didn't notice. I think the only way to be sure is to drive a similar Ranger Hybrid, when I get the chance.

But even before that, when shifting between R and D, there was and still is a slight vibration. Is it the same on your Rangers with a 10-speed transmission?

Some vibration when shifting the transmission from Reverse to Drive and vice-versa is normal, especially if the transmission is still cold. It’s something every vehicle I have ever driven does. Now, if there is a loud shutter in the truck, that is a different issue.
The transmission isn’t small, so you might feel some vibrations at times when it shifts, but it should be barely noticeable. Like if you are pushing on the brake pedal and then suddenly lift, occasionally I will feel truck catch just a little. Again, unless it is shifting extremely rough, it’s not an issue.
Btw, what do you mean by Ranger Hybrid?

Europe gets a hybrid Ranger this year

Thank you. I meant Ford Ranger PHEV 2.3l

Your Transmission will be fine.
It is your Transfer Case that will be damaged - possibly catastrophic damage, and BIG $$$ to replace !

Doing what you describe having done, just a little bit, isn't going to hurt anything. But if that continues for a significant distance, then that could be very bad.
Before a Transfer Case blows apart from the stress, it usually makes a lot of loud/noticeable groaning sounds to warn you.
Best practice is to only use 4H or 4L on dirt, gravel, sand, or snow/ice; and never on hard surfaces like asphalt (unless it is very wet & slippery).

I predict that you are going to have a lot fun with your new 4WD Ranger

That's for sure
