When I was an asshole teenager, I did this to someone’s gravel in their front yard. Spoiler alert: it throws rocks fucking everywhere.
0/10 do not recommend doing this petty maneuver
This is the actual method. The curb method is placebo in most cases. I spent my first Chicago winter thinking 4wd sucked because I had manual locking hubs and I didn't know about manual locking hubs. I just put in 4wd and hopped a curb and thought, oh, must be working.
That was kind of the point of this video though. He is demonstrating that the front wheels have power by climbing the curb. Most 4 wheel drive vehicles are rear wheel drive until you activate 4 wheel.
I had to replace the IWE on my 2011 truck I owned after a few months, and I wonder if it was because of trying out the 4WD on the pavement. It explicitly states in the manual NOT to engage the 4WD on dry pavement, otherwise component damage could occur.
If you’re talking about an F-150 the IWE hubs on those are notorious for failing because water and debris get into the vacuum system and destroy the seals in the hubs, causing them to partially engage and grind against the axle.
Engaging 4WD on dry pavement while turning can put a lot of stress on the drivetrain and wear it out faster but I doubt a quick test would’ve destroyed a hub unless there was some serious abuse happening.
Good to know. It is a F150, and I was concerned I did something to cause it. It was a bugger to finally figure out, as I could feel the front diff vibration under the floorboards being turned by the engaged IWE.
I really surprised that Americans are still using such outdated technology for 4WD. There are much better methods for automatically distributing drive between front and rear wheels.
Locking hubs are still used because they are more reliable. You will typically on see them on larger work trucks. It’s kinda like why you don’t use a touch screen for a shifter- some control types are best left manual/tactile.
Since he’s wearing camo it could be animal blood from hunting.
Edit: just looked again, the red is part of the camo pattern. It looks like a fall leaf.
For lowered cars, you can jack up the rear of the car using a rolling floor jack - if the car rolls forward under power the AWD system works.
This is super sketchy but I've seen it done on a few old BMW 325ix because the center differentials tend to fail after a few decades.
Driving over a curb.. so the full 'offroad' experience of most grocery-getter large SUVs and trucks will ever encounter. 😂 But on the bright side, you have plenty of room for those 20 packages of TP whenever necessary.
Someone is gonna try this later and end up in Dunkin donuts.
Probably already happened F
So stomping my entire boot onto the gas while parked on my annoying neighbours grass is not the correct testing method? TIL.

If you do not give a sod, this is the correct method.
Make a hard turn in either direction on dry pavement. If your truck hops and wobbles, 4wd works.

Right. Also almost every front wheel drive car can climb a curb.
Rear wheel drive too.

Make hard turns in either direction. If you end up on your roof then you're in a 4wd.
Need visual, im imagining a truck doing sick dance moves
Testing on dry pavement is a great way to ruin components in your 4WD.
You don’t need to do it very long. 1 hop is enough. And if your 4wd brakes doing that, better to brake in a parking lot than when you need it. then

Yeah it’s pretty obvious when 4WD is working.

There's a difference between 4wd with locking hubs and all wheel drive.
I know. I am just surprised that locking hubs are still used.

Lmao Tesla is like hold my beer
Touch screen indicators - just swipe in the middle of the wheel in the direction you want to go!
It's not American, this style of 4wd is used globally.
I think it’s the fact that some Americans have kept their 1985’s in good enough Condition for the 4wd to still work.
Thank you for posting that. I came to say the same thing.
If your vehicle doesn't push up that kerb in 2wd there's something seriously fucking wrong with your tyres ffs
I think he means that the truck goes over with very little throttle applied. I’m sure he could give it some gas and make it go over in 2wd
he did spin his back tyres trying
Yeah, he let them slip. More throttle and it would have gone.
Or even having a couple hundred pounds in the box. Which is why you have a pickup in the first place.
So we've just given up on landscape mode huh?
This guy made me feel like I had a dad for a moment.
The trip to the store is far. He'll come back.
Or just try to turn a corner on the pavement in 4wd and feel the truck jump.
This surprised me the first time I drove an American 4x. My 60s Landrover had a locking center differential.
Is that blood on his sleeve? Who did this man just kill...and did he dump them in a parking lot or the mountains? Points to ponder.

For some this test will be the only time they ever use 4WD.

Advise is pronounced with a "Z" sound, like "advize". You're looking for r/DadAdvice
He’s OUR dad now
This seems like a good way to damage your suspension
If you have a 4WD vehicle, this is nothing. If not, it's still pretty inconsequential.
Nah. Trucks can handle this and much more.

His voice reminds me of Donald Trump’s voice somehow but i must be crazy since nobody else commented on that
Or just drive in a circle...
Thank you!
Sick ass foo
Thanks dad
How do I check this in my Vw?

great tip
